Your equation is wrong

the first is suppoosed to be 3(45), you wrote 5(45) but it should be 3(45), it's 3 trips, not 5

the other part is right tho, it is 6h

so 3(45)+6h=303 is the right equation

remember, you can do anything to an equation as long as you do it to both sides

so first expand 3(45)

3(45)=135

135+6h=303

minus 135 both sides

6h=168

divide both sides by 6

h=28

the hourly rate is $28 per hour

**Answer:**

1

**Step-by-step explanation:**

**Answer:**

**Step-by-step explanation:**

**-5x - 3 = 2x - 18 **

-2 -2

-8x - 3 = -18

+ 3 +3

-8x = -15

/-8 /-8

x = 2.875

If you're doing the equal side

If you're not you would do

-5x -3 = 180

+ 3 +3

-5x = 183

/5 /5

x = 36.6

2x - 18 = 180

+18 +18

2x = 198

/2 /2

x = 99

√(x^100y^16) look for perfect squares to move out from under the radical

√(x^50*x^50*y^8*y^8)

x^50*y^8 (third one down :P)

**Answer:**

D

**Step-by-step explanation:**

when there are exponents with same bases multiplied by each other, keep the base and add the exponents

4^(3)+4^(5)=4^8

4^8 is D in this question
