Answer:
$188
Step-by-step explanation:
first you would do 87 + 7 which is 94
then multiply it by 2 which is 188
hope this helps :)
Answer:
The original price of the jacket was $188
Step-by-step explanation:
1/2x - 7 = 87
+7 +7
1/2x = 94
x2 x2
x = 188
Write the linear equation in Slope-Intercept Form y = mx + b of the line that passes through the given points, then graph
the line.
Answer:
y = 3x + 7.
To graph the line mark off the 2 points and draw a line through them.
Step-by-step explanation:
The slope = (-2-7) / (-3-0)
= -9/-3
= 3.
The value of b is found using the point-slope form of a line:
y - y1 = m(x - x1)
using m = 3, (x1, y1) = (0, 7):
y - 7 = 3(x - 0)
y = 3x + 7.

Answer:
1) 10x
2)360-(5x+20)-10x-(7x-8) (I think?)
3) 7x-8
4) 5x+20
Step-by-step explanation:
Answer:
x=15.8degrees
Step-by-step explanation:
10x+5x+7x+20-8=360
22x+12=360
=22x=360- 12
22x=348
x=15.8 degrees
X=-4y + 4

If x = 2 work out the value of 4x 2
Answer:
16
Step-by-step explanation:
First plug in 2 as the "x" in 4x
so 4 times (2) times (2)
and if you mutiple 4 x 2 you get 8
then 8 times 2 is 16
5. The largest mosaic in the world is on the walls of the central library of the
Universidad Nacional Autonoma de Mexico in Mexico City. The mosaic depicts
scenes from the nation's history and covers an area of 4000 m2. If the entire
mosaic were on one square wall, what would the dimensions be? Estimate your
answer to the nearest whole number and then use your calculator to get the
length to the nearest HUNDRETH.
Answer:
63.25mStep-by-step explanation:
The area of the square wall = L² where;
L is the length of the wall.
Given
Area of the mosaic = 4000m²
Substitute into the formula and get L
4000 = L²
Square root both sides
√4000 = √L²
√4000 = L
Rearrange
L = √4000
L = 63.25m (to the nearest hundredth)
Hence the length to the nearest hundredth is 63.25mAbout this question, look at the photo

Prove the sum of two rational numbers is rational where a, b, c, and d are integers and b and d cannot be zero. Fill in the missing step in the proof.
Answer:
We conclude that the sum of two rational numbers is rational.
Hence, the fraction will be a rational number. i.e.
[tex]\frac{ad+cb}{bd}[/tex] ∵ b≠0, d≠0, so bd≠0Step-by-step explanation:
Let a, b, c, and d are integers.
Let a/b and c/d are two rational numbers and b≠0, d≠0
Proving that the sum of two rational numbers is rational.
[tex]\frac{a}{b}+\frac{c}{d}[/tex]
As the least common multiplier of b, d: bd
Adjusting fractions based on the LCM
[tex]\frac{a}{b}+\frac{c}{d}=\frac{ad}{bd}+\frac{cb}{db}[/tex]
[tex]\mathrm{Since\:the\:denominators\:are\:equal,\:combine\:the\:fractions}:\quad \frac{a}{c}\pm \frac{b}{c}=\frac{a\pm \:b}{c}[/tex]
[tex]=\frac{ad+cb}{bd}[/tex]
As b≠0, d≠0, so bd≠0
Therefore, we conclude that the sum of two rational numbers is rational.
Hence, the fraction will be a rational number. i.e.
[tex]\frac{ad+cb}{bd}[/tex] ∵ b≠0, d≠0, so bd≠0Starting with number 0 on my calculator, I do a calculation in five steps. At each step, I either add 1 or multiply by 2. What is the smallest number that cannot be the final result?
Answer:
assuming only positive integers, the answer is 1
Step-by-step explanation:
the smallest number that you can get by adding is:
start with 0then add 1 = 1add another 1 = 2add another 1 = 3add another 1 = 4add another 1 = 5but you can also multiply, and anything multiplied by 0 is 0:
start with 0multiply by 2 = 0multiply by 2 = 0multiply by 2 = 0multiply by 2 = 0multiply by 2 = 0The question does not say that we need to do any specific calculation, it only gives us 2 options and we can choose them as many times as we want.

what does 9a-2=12+2a
Answer:
a=2
Step-by-step explanation:
Subtract 2a from both sides.
9a−2−2a=12
Combine 9a and −2a to get 7a.
7a−2=12
Add 2 to both sides.
7a=12+2
Add 12 and 2 to get 14.
7a=14
Divide both sides by 7.
a=[tex]\frac{14}{7}[/tex]
Divide 14 by 7 to get 2.
a=2

a man earned and interest of 240 in 4 years at 20%per annum simple interest. calculate the principal
Answer:
Step-by-step explanation:
P x 20/100 x 4=240
1/5 x 4p =240
4/5p x5=240 x 5
4p/4=1200/4
p=300
We need I = prt.
240 = p(0.20)(4)
240/[(0.20)(4)] = p

2. The envelope below has a mailing label. L(x) = 6x + 5 W(x) = 6x + 5 M(x) = x +4 NOx) = x + 2 MR. AL GEBRA 123 INFINITY WAY POLYNOMIAL, XY 11235 a. Let A(x) = L(x).W(X) - M(x)•N(x). Find A(x).
Answer:
A(x) = 35x² + 54x + 17
Step-by-step explanation:
Relation in the polynomials has been defined as,
A(x) = L(x).W(x) - M(x).N(x)
L(x) = (6x + 5)
W(x) = (6x + 5)
M(x) = (x + 4)
N(x) = (x + 2)
By substituting the polynomials in the expression,
A(x) = (6x + 5)(6x + 5) - (x + 4)(x + 2)
= (6x + 5)² - (x + 4)(x + 2)
= (36x² + 60x + 25) - (x + 4)(x + 2) [Since, (a + b)² = a² + 2ab + b²]
= (36x² + 60x + 25) - [x(x + 2) + 4(x + 2)]
= (36x² + 60x + 25) - [x² + 2x + 4x + 8]
= (36x² + 60x + 25) - [x² + 6x + 8]
= (36x² - x²) + (60x - 6x) + (25 - 8)
= 35x² + 54x + 17
A(x) = 35x² + 54x + 17
can someone please tell me how to solve this
Answer:
21.33 units (rounded)
Step-by-step explanation:
The height, x, can be determined through the Pythagorean Theorem:
a^2+b^2=c^2 (where b will be our height)
(22/2)^2+b^2=24^2
121+b^2=576
b^2=455
b=21.33072901
So the height is about 21.33 units
