You need to divide the two numbers. 15/3 = 5

For every 5 days you do 1 job

5:1

__Answer:__

**4) x = 3/2 , x = -1/2**

__Steps:__

(2x-1)² - 4 = 0

4x²-4x+1 - 4 = 0

4x²-4x-3 = 0

x = (4±√((-4)²-4×4×(-3))/2×4

x = (4±√(16+48)/8

x = (4±√(64)/8

x = (4±8)/8

x = 12/8 , x = -4/8

**x = 3/2 , x = -1/2**

This is not distributive but ok

2x-4(4)=10(4)

2x-16=40

add 16 both sides

2x=56

divide 2

x=28

**Answer:**

15/36 (41.667%)

**Step-by-step explanation:**

**Answer:**

21.5 feet.

**Step-by-step explanation:**

Calculate the length of a curved edge.

s =

m

360

· 2πr Use the formula for arc length.

=

90

360

· 2π(3) Substitute 3 for r and 90 for m.

= 1.5π Simplify.

Let t be the length of the cut encompassing the tray.

t = 2 · 1.5π + 2 · 6

= 3π + 12 Simplify.

≈ 21.5 ft Use a calculator to evaluate. Then round your answer to the nearest half foot.

The length of the cut encompassing the tray is 21.5 feet.
