Answer:
Jaycee sold 28 candy bars
Step-by-step explanation:
Jayce and Rylee are selling candy bars for a school fundraiser. Rylee sold 84 candy bars and raised $210. If Jayce raised $70, how many candy bars did he sell?
From the above question:
$210 = 84 candy bars
$70 = x candy bars
Cross Multiply
210 × x = 70 × 84
x = 70 × 84/210
x = 28 candy bars
Therefore, Jaycee sold 28 candy bars
Answer:
48 inches
Step-by-step explanation:
There are 12 inches in 1 foot. So multiply by 12 to convert from feet to inches.
4 × 12 = 48
4 feet = 48 inches
TO figure out, we need to plug in x=0 and then check if y = 7.
And the answer is B, y = x + 7, <span>because at x=0, we have y = 0 + 7 = 7, which matches the given point (0,7)</span>
Yes since technically they're fractions
