Find three consecutive even integers such that when the first integer is
multiplied by the third integer, the result is 2 more than 5 times the
second integer. [Only an algebraic solution will be accepted.]
Answer:
4, 6, 8
Step-by-step explanation:
Let the three consecutive integers be a, b, and c.
So, first, we know that they are three consecutive even integers. In other words:
[tex]a=2n,b=2n+2,c=2n+4[/tex]
N is any integer, but the 2n ensures that the outcome is even. Since we want to make the subsequent terms also even, we add 2.
We are told that when the first integer (a) is multiplied by the third integer (c), the result is 2 more than 5 times the second integer (b). In other words:
[tex]ac=2+5b[/tex]
Substitute:
[tex](2n)(2n+4)=2+5(2n+2)[/tex]
Distribute both sides:
[tex]4n^2+8n=2+10n+10[/tex]
Add on the right:
[tex]4n^2+8n=10n+12[/tex]
Subtract 10n and 12:
[tex]4n^2-2n-12=0[/tex]
Divide everything by 2:
[tex]2n^2-n-6=0[/tex]
Factor. Find two numbers that when multiplied equals (2)(-6)=-12 and when added equals -1.
3 and -4 works. Thus:
[tex]2n^2-4n+3n-6=0\\2n(n-2)+3(n-2)=0[/tex]
Combine:
[tex](2n+3)(n-2)=0[/tex]
Zero Product Property:
[tex]2n+3=0\text{ or } n-2=0[/tex]
Solve for n:
[tex]n=-3/2\text{ or } n=2[/tex]
So, n is either -3/2 or 2.
That means that a must be either:
[tex]a=2(-3/2)\text{ or } 2(2)[/tex]
Multiply:
[tex]a=-3\text{ or } 4[/tex]
The first answer is not even. So:
[tex]a=4[/tex]
Our first answer is 4.
And our sequence is 4, 6, and 8.
Checking:
4 times 8 is 32.
2 plus 5 times 6 is also 32.
So our answer is correct.

A rectangle length is 5 more than its width. If the premiditer of the rectangle is 66 inches, what is the length of the rectangle
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{19 \: inches}}}}}[/tex]
Step-by-step explanation:
Let the width be 'w'.
Length of a rectangle ( l ) = 5 + w
Perimeter of a rectangle = 66 inches
First, finding the width of a rectangle
[tex] \boxed{ \sf{perimeter \: of \: rectangle = 2(l + w)}}[/tex]
[tex] \dashrightarrow{ \sf{66 = 2(5 + w + w)}}[/tex]
[tex] \dashrightarrow{ \sf{66 = 2(5 + 2w)}}[/tex]
[tex] \dashrightarrow{ \sf{66 = 10 + 4w}}[/tex]
[tex] \dashrightarrow{ \sf{10 + 4w = 66}}[/tex]
[tex] \dashrightarrow{ \sf{4w = 66 - 10}}[/tex]
[tex] \dashrightarrow{ \sf{4w = 56}}[/tex]
[tex] \dashrightarrow{ \sf{ \frac{4w}{4} = \frac{56}{4} }}[/tex]
[tex] \dashrightarrow{ \sf{w = 14 \: inches}}[/tex]
Width of a rectangle ( w ) = 14 inches
Now, Substituting / Replacing the value of w in order to find the length of rectangle
[tex] \sf{length = 5 + w}[/tex]
[tex] \dashrightarrow{ \sf{length = 5 + 14}}[/tex]
[tex] \dashrightarrow{ \sf{19 \: inches}}[/tex]
Length of a rectangle = 19 inches

Which expression is equivalent to StartRoot negative 80 EndRoot? Negative 4 StartRoot 5 EndRoot Negative 4 StartRoot 5 EndRoot i 4 StartRoot 5 EndRoot i 4 StartRoot 5 EndRoot
Answer:
(4√5)i
Step-by-step explanation:
Complex number is a number in the form a + bi, where both a and b are real numbers. A complex number has two parts, the first part a is the real part of the complex number and the second part b is the imaginary part of the complex number. Also, i = √(-1), hence i² = -1.
Complex numbers can also be graphed on the complex plane.
√(-80) = √(-1) × √(80)
But since √(-1) = i
√(-80) = i × √80 = i × √16 × √5 = i × 4 × √5 = (4√5)i
√(-80) = (4√5)i
Answer:
C) 4 Square Root 5 i

What is the slope of a line perpendicular to the line whose equations is x-y=6
Answer:
m = -1
Step-by-step explanation:
First write the line in slope intercept form y = mx+b where m is the slope and b is the y intercept
x-y = 6
subtract x from each side
-y = -x+6
Multiply each side by -1
y = x-6
The slope is 1
Perpendicular lines have slopes that multiply to -1
m * 1 = -1
m = -1
The slope of the perpendicular line is -1
For the EOQ model, which of the following relationships is incorrect?
a. As the order quantity increases, the number of orders placed annually decreases.
b. As the order quantity increases, annual holding cost increases.
c. As the order quantity increases, annual ordering cost increases.
d. As the order quantity increases, average inventory increases.
Answer: As the order quantity increases, annual ordering cost increases
Step-by-step explanation:
The Economic Order Quantity (EOQ) is simply referred to as the amount of units that should be added by a company to its inventory with each order in order to minimize total inventory costs such as order costs, holding costs, and shortage costs.
The incorrect option is that "as the order quantity increases, annual ordering cost increases". It should be noted that ordering costs are simply the expenses that are incurred in order for an order to be created and processed to a supplier. It should be noted that as the ordering quantity increases, it doesn't mean that the annual ordering costs also increase.

Passports. In 2006, approximately 71 million valid
passports were in circulation in the United States.
This number increased to approximately 102 million
in 2011. What is the percent increase?
Answer:
0.437%
Step-by-step explanation:
given:
initial number = 71 M
final number = 102M
increase = final number - initial number
= 102 - 71
= 31 M
Percent increase
= increase / initial number x 100%
= (31 / 71) x 100%
= 0.437%
No. of valid passports in 2006 = 71M
No. of valid passports in 2011 = 102M
We have to find percentage increase in the number of passports[tex].[/tex]
[tex]\leadsto\sf\:\% Increase = \dfrac{N_2-N_1}{N_1}\times 100[/tex]

Without using a calculator, choose the statement that best describes the value of the square root of 46
i need help :(
Answer:
The value of √46 is between 6.5 and 7.
Step-by-step explanation:
We can use perfect squares to solve this problem.
1² = 1
2² = 4
3² = 9
4² = 16
5² = 25
6² = 36
7² = 49
A square root reverses the squaring operation. Therefore, if we take the square root of 49, we will get 7.
So, because 46 fits in the interval 36 < 46 < 49, we can solve this problem.
√36 = 6
√46 = ?
√49 = 7
Therefore, using this information, we can see that clearly the value of 46 is closer to 49, meaning that the square root of 46 is between 6.5 and 7.

235 people are at RSM summer camp. There are 35 more boys than girls, and 70 fewer adults than girls. How many people of each group are at the camp? PLS DO IT QUICK
Answer:
Number of girls = 90
Number of boys = 125
Number of Adults = 20
Step-by-step explanation:
Let us represent:
The number of girls = g
The number of boys = b
Number of Adults = a
235 people are at RSM summer camp.
Hence,
g + b + a = 235 .......Equation 1
There are 35 more boys than girls, and 70 fewer adults than girls.
b = g + 35
a = g - 70
Hence we substitute g + 35 for b and g - 70 for a in Equation 1
g + b + a = 235 .......Equation 1
g + g + 35 + g - 70 = 235
3g + 35 - 70 = 235
3g - 35 = 235
3g = 235 + 35
3g = 270
g = 270/3
g = 90
Hence, there are 90 girls in the party.
Number of boys is calculated as:
b = g + 35
b = 90 + 35
b = 125
Number of Adults is calculated as:
a = g - 70
a = 90 - 70
a = 20
How many people of each group are at the camp?
Number of girls = 90
Number of boys = 125
Number of Adults = 20
Answer:
There are 90 girls, 125 boys, and 20 adults.
Step-by-step explanation:
Let x be the number of girls. How many boys were there?
x + 35
How many adults were there?
x - 70
We know that 235 people are at RSM summer camp. Use this to make an equation.
x + (x + 35) + (x - 70) = 235
x + x + 35 + x - 70 = 235
3x - 35 = 235
3x - 35 + 35 = 235 + 35
3x = 270
3x ÷ 3 = 270 ÷ 3
x = 90
x, x + 35, x - 70
90, 125, 20

Solve for x
x - 7 = 8
Answer: x = 15
Step-by-step explanation: In this problem, since 7 is being subtracted
from x, add 7 to both sides of the equation to get x by itself.
On the left side, -7 + 7 will cancel out and
on the right side, 8 + 7 simplifies to 15.
So x = 15.
The value of x in the given equation x - 7 = 8 is 15.
Given that an equation x - 7 = 8, we need to solve for x.
To solve for x in the equation x - 7 = 8, you want to isolate x on one side of the equation.
Follow these steps:
Step 1: Add 7 to both sides of the equation to isolate x on the left side:
x - 7 + 7 = 8 + 7
Simplifying the left side, the -7 and +7 cancel out, leaving:
x = 15
Step 2: Check your solution by substituting the value of x back into the original equation:
x - 7 = 8
Substitute x with 15:
15 - 7 = 8
Simplify the left side:
8 = 8
Since the left side equals the right side, we have verified that x = 15 is indeed the correct solution for the equation.
Hence, the answer is x = 15.
