Answer:
A . The numbers are 6 and 7, with the smaller number as 6
B. The number is 135
Step-by-step explanation:
A. Let the numbers be a and b
adding both gives 13
a + b = 13 •••••(i)
difference between the two is 1
b - a = 1 ••••••(ii)
So we have two equations that we can solve simultaneously;
b = 1 + a; Substitute this into 1
a + 1 + a = 13
2a + 1 = 13
2a = 13-1
2a = 12
a = 12/2
a = 6
b = a + 1 = 6 + 1 = 7
The numbers are 6 and 7 while 6 is the smaller number
B.Let the number be x
Divide by 5; x/5, then subtract 2 , we get 25
x/5 - 2 = 25
x/5 = 25 + 2
x/5 = 27
x = 5 * 27
x = 135

Given the points R(-4, 5) and S(2, -1). Find RS, the midpoint of RS, and point P which is 13 of the distance from R to S. Leave your answer as a simplified radical.
Answer:
Step-by-step explanation:
Given the points R(-4, 5) and S(2, -1), to get the distance between the points, we will use the formula;
D = √(x2-x1)²+(y2-y1)²
Given x1= -4, y1 = 5, x2 = 2 and y2 = -1
RS = √(2-(-4))²+(-1-5)²
RS = √(6)²+(-6)²
RS = √36+36
RS = √72
RS = √2×36
RS = 6√2units
To get the midpoint, we will use the formula M(X,Y) = (x1+x2/2, y1+y2/2)
(X,Y) = (-4+2/2, -1+5/2)
(X,Y) = (-2/2, 4/2)
(X,Y) = (-1,2)
Hence the midpoint is (-1,2)
To get a point P 1/3 of the distance of RS, we will multiply 1/3 with the the distance RS as shown
P = 1/3 × 6√2
P = 2√2

5^(9 - 3x) = 1255^(9 - 3x) = 5^39 - 3x = 33x = 9 - 33x = 6x = 6/3x = 2The length of each edge of a cube is x centimeters. If x is an integer, why can't the volume of the cube equal 15cm. Show work please
Let's try some integer values of x to see what volumes we get
If x = 0, then x^3 = 0^3 = 0*0*0 = 0If x = 1, then x^3 = 1^3 = 1*1*1 = 1If x = 2, then x^3 = 2^3 = 2*2*2 = 8If x = 3, then x^3 = 3^3 = 3*3*3 = 27We do not get 15 as a result in that list above. So there are no integer solutions to x^3 = 15
In other words, the value [tex]\sqrt[3]{15}[/tex] is not an integer.

Sam works at a used car dealership, where he earns 7% commission on each sale. If he sells a car for $12,000 and another for $17,500, how much commission does Sam earn?
Answer:
$2,065
Step-by-step explanation:
The computation of the commission earned by Sam is shown below:
For each sale, he gets 7% commission
So,
For $12,000, the commission amount is
= $12,000 × 0.07
= $840
And, for another sale i.e. $17,500, the commission amount is
= $17,500 × 0.07
= $1,225
So, the total commission he earned is
= $840 + $1,225
= $2,065

Solve the two following simultaneous equations and find the possible values of x and y. [tex]x^2 +y^2-2xy = 64[/tex]
[tex]x^2 - y^2 = 40[/tex]
Step-by-step explanation:
If u assume x=y=1, then x+y=2 and x^2+y^2=2
And now, xy=1.
Therefore x=y=1.
Let me know, if anyone come with other answers too.

Step-by-step explanation:
(*) x^2 + y^2 - 2xy = 64
<=> (x - y)^2 = 64
<=> x - y = 8 or x - y = -8
(**) x^2 - y^2 = 40
<=> (x - y)(x + y) = 40
Case 1: x - y = 8
(**) <=> 8(x + y) = 40
<=> x + y = 5
we have: x+y = 5 and x-y = 8
--> x = (5+8)/2 = 6.5
--> y = x - 8 = 6.5 - 8 = -1.5
so (x,y) = (6.5 , -1.5)
Case 2: x - y = -8
(**) <=> -8(x + y) = 40
<=> x + y = -5
we have: x + y = -5 and x - y = -8
--> x = [ (-5) + (-8) ]/2 = -6.5
--> y = -5 - x = -5 + 6.5 = 1.5
so (x,y) = (-6.5 , 1.5)
Answer: (x,y) = (6.5 , -1.5) and (-6.5 , 1.5)

Evaluate f(8) =(8-5)2 for f(8)
X=8
Answer: f(8) = 9
Step-by-step explanation:
PEMDAS: Solve for parenthesis first.
f(8)= (8-5)^2
(3)^2
Square that, you get 9.

What is the range of the function for the given domain?
y = 2x - 5
D: (-2,0, 2,4}
Select the correct answer.
OR: {-9, 0,-1,3}
OR: {9,-5, 9, 13}
OR: {-9, -5, -1,3}
OR: {-9, 0, 9, 13}
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ - 9 \: , \: - 5 \: , - 1 \: , \: 3 \: }}}}}[/tex]
Option C is the correct option.
Step-by-step explanation:
Here, y = 2x - 5 and domain ( D ) = { -2 , 0 , 2 , 4 )
when, x = -2 , Range = 2 × (- 2)- 5 = - 4 - 5 = -9
when, x = 0 , range = 2 × 0 - 5 = 0 - 5 = -5
when x = 2 , range = 2 × 2 - 5 = 4 - 5 = -1
when, x = 4 , range = 2 × 4 - 5 = 8 - 5 = 3
Range = { -9 , -5 , -1 , 3 }
Hope I helped!

HELP ME PLEASE!!!!!!
Beth enlarged the triangle below by a scale of 5. She found the area of the enlarged triangle. Her work is shown below.
What was Beth’s error?
She should have divided One-half (4) (3.5) by 5.
She should have divided One-half (4) (3.5) by 5 squared.
She should have multiplied (4) (3.5) by 5.
She should have multiplied One-half (4) (3.5) by 5 squared.
Answer:
The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.
Step-by-step explanation:
Originally Triangle has height =3.5cm and width=4cm
Beth enlarged the same triangle by scale of 5 and calculate area of triangle
The area of triangle as given as A= $$\frac{1}{2} \texrm{ (base) (height)}$$
Area of original triangle is A =$$\frac{1}{2}(3.5 \times 4)$$
Since, The triangle is enlarged by scale of 5
New height =3.5x5 = cm and new width=4x5cm
Area of new triangle is
A' = $$\frac{1}{2} (\textrm{new width} ) ( \textrm{new height})$$
A' = $$\frac{1}{2}(3.5 \times 5)(4\times 5)$$
A' = $$\frac{1}{2}(3.5 \times 4)(5^{2})$$
A' = $$A (5^{2})$$
Now, Looking what error beth made is:
Beth found Area of new triangle is A' = $$\frac{1}{2}(3.5)(4)(5)$$
The possible error made by Beth is directly multiplying scale of 5 to area of original triangle and getting area of enlarged triangle, which is wrong.

[tex]\frac{-75.888}{-3.1(4.8)}[/tex]
[tex]\frac{-75.888}{-14.88}[/tex]
[tex]5.1[/tex]
Hope this helps.
頑張って!
Answer:
5.1
Step-by-step explanation:
first you subtract -44.288 - 31.6= -75.888
then subtract 6-1.2= 4.8
then multiply -3.1x4.8= -14.88
then divide -75.888/-14.88= 5.1

Answer:
a)12
b)1/12
c)4/12
Step-by-step explanation:
a) the coin is a 1/2 and the dice is 1/6 so you times the bottom number and you get 12
b) since that is a exact one way to get it has to be 1/12 chance
c) so to only get a tails it would be 6/12 and less than 5 means you can get 1,2,3, and 4 so that is 4 ways out of 12 ways so its 4/12
