Answer:
Step-by-step explanation:
<u>We know that:</u>
- 12 ounce box of cereal = $3.84
<u>Work:</u>
- 12/3.84 ounce box of cereal = $1
- => 12/3.84 x 2.49 box of cereal = $2.49
- => 7.78 ounces (Rounded to nearest hundredth) = $2.49
Hence, 7.78 ounces cost $2.49.
Answer: C) add 5 to both sides
The given equation is
(4/7)x - 5 = -13
To solve this, we follow PEMDAS in reverse undoing each operation. Normally parenthesis is the first thing we look for, but instead we start with subtraction.
So we'll undo subtraction which means we add 5 to both sides
It would be basically 2.12 because once you divide it your answer will be that
F(3) = $4 + $2.5(3)
f(3) = $4 + $7.5
f(3) = $11.50
