Answer:
w = -4
Step-by-step explanation:
<u>Step 1: Distribute</u>
-2w - 14 = 2(w + 1)
-2w - 14 = 2w + 2
<u>Step 2: Add 2w to both sides</u>
-2w - 14 + 2w = 2w + 2 + 2w
-14 = 4w + 2
<u>Step 3: Subtract 2 from both sides</u>
-14 - 2 = 4w + 2 - 2
-16 = 4w
<u>Step 4: Divide both sides by 4</u>
-16 / 4 = 4w / 4
<em>-4 = w</em>

Answer: w = -4
Answer:
0.646 radians to the nearest thousandth.
Step-by-step explanation:
To convert degrees to radians we multiply by π/180
= 37 * π/180
= 0.20556π radians
= 0.646 radians to the nearest thousandth.
For this case, the first thing we must do is define variables:
x: number of quarters
y: number of nickels
We now write the system of equations:
x + y = 68
0.25x + 0.05y = 13.40
Solving the system we have:
x = 50
y = 18
Answer:
they have:
quarters = 50
nickels = 18
Answer:
1x-1y
