Multiply both sides by 7.
-5 * 7 = c/7 * 7
-5 * 7 = c
c = -35
Your final answer is c = -35.
Answer:
$2.47
14.6%
Step-by-step explanation:
Total of the original prices:
$3.99 + $6.99 + $5.99 = $16.97

He saved $2.47.
The percent he saved is
2.47/16.97 × 100% = 14.6%
Use FOIL
28x² -8xy +7xy -2y²
28x² -xy -2y²
I^2 = (sqrt-1)^2 then the square cancels out so the answer is just
-1
