14, because 2x7=14. Every gift box uses 2 feet on ribbon. There are 7 gift boxes, so she needs 2+2+2+2+2+2+2 length of ribbon.
If n is a negative number, x would be less than -8.
Perimeter = 2L + 2W
42= 2L + 2(8)
26 = 2L
13 = L
Simplify
f(x) = 3 + 11
Multiple
fx = 3x + 11
<span>Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = 11x-1 + 3
Simplifying
f = 11x-1 + 3
Reorder the terms:
f = 3 + 11x<span>-1</span></span>
Answer:
$4.94
Step-by-step explanation:
Gummy worms cost $2.96 per lb, and she bought 4.25 lbs, so:
2.96 * 4.25 = $12.58 spent in gummy worms
Jaw breakers cost $4.95 per lb, and she bought 0.5 lbs, so:
4.95 * 0.5 = $2.48 spent in jaw breakers
Adding the gummy worms and the jaw breakers, she spent:
12.58 + 2.48 = 15.06 in Total
She gave the clerk $20.00, but she only spent only $15.06, so the clerk gave her back the difference:
20 - 15.06 = $4.94 is the change that she received
