Answer:

x = 3

Step-by-step explanation:

15 - x = 2(x + 3)

15 - x = 2x + 6

15 - x - 2x = 6

-x - 2x = 6 - 15

-3x = 6 - 15

-3x = -9

x = 3

Find x no need for explanation I just need answer thanks

ikadub [295]

Answer:

x = 12 m

Step-by-step explanation:

Length = x m

Width = 3⅔ = 11/3

Area = 44 m²

Area of rectangle = length × width

Plug in the values into the equation

$44 = x \times \frac{11}{3}$

$44 = \frac{11x}{3}$

Multiply both sides by 3

$44 \times 3 = \frac{11x}{3} \times 3$

$132 = 11x$

Divide both sides by 11

$12 = x$

x = 12

Item 6 Your friend earns $10.50 per hour. This is 125% of her hourly wage last year. How much did your friend earn per hour last

tester [92]

Answer:

$8.40

Step-by-step explanation:

We can write a proportion to find the total amount last year using the information given. A proportion is two equivalent ratios set equal to each other.

$\frac{125}{100}=\frac{10.50}{y}$

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.

125(y)=100(10.50)

125y=1050

y=8.40
