Answer:

x=5

Step-by-step explanation:

(8x-8)3/2=64

(24x-8)/2=64 -You are distributing the three

12x-4=64 -You divide the whole thing by two

12x=60 -You subtract the four from both sides

x=5 - You divided the twelve from both sides

Hope this helps!

Least to greatest -2, -3/4, -0.45, 3%, 0.36

Crank

Answer:

$\large\boxed{-2,\ -\dfrac{3}{4},\ -0.45,\ 3\%,\ 0.36}$

Step-by-step explanation:

We convert some numbers to decimal fractions:

-2 = -2.00

-3/4 = -0.75

-0.45

3% = 0.03

0.36

We order

-2, -0.75, -0.45, 0.03, 0.36

$\dfrac{3}{4}=\dfrac{3\cdot25}{4\cdot25}=\frac{75}{100}=0.75$

other method

$\dfrac{3}{4}=3:4=0.75$ (use a calculator)

$p\%=\dfrac{p}{100}\to 3\%=\dfrac{3}{100}=0.03$

Which Function rule describes the pattern in the table? x:-2,-1,0,1,2 / y:14,11,8,5,2 A) y=3x+8 B) y= -3x-8 C) y=3x-8 D) y=-3x+8

Leona [35]

For every value tht x increases, y decreases by 3

-3x

Then to find the y intercept, look at 0's corresponding value (8)

-3x+8

The ratios of the measure of the sides of a triangle is 4:10:7. Find the length of each side of the perimeter of the triangle is

dangina [55]

The given ratio of the sides of the triangles is 4:10:7. Let the sides be 4x, 10x and 7x .

And given perimeter is 252 meters .

Perimeter is the sum of all sides. So we get

$4x+10x+7x=252 \\ 21x = 252$

Dividing both sides by 21

$x = 12$

So the sides are

$4*12=48 meters \\ 10*12=120 meters \\ 7*12= 84 meters$

Amanda and Ndiba are selling flower bulbs for a school fundraiser. Customers can buy packages of tulip bulbs and bags of daffodi

Mumz [18]

Answer:

daffodil = $13 Tulip = $7

Step-by-step explanation:

6t + 12d = 198

7t + 6d = 127

6t = 198 - 12d

t = 33 -2d

substitute

7(33-2d) + 6d = 127

231 -14d +6d = 127

- 8d = -104

d =13

6t + 12(13) = 198

6t +156 = 198

6t = 42

t = 7
