2 answers:

16x-15-9x=13, you would combine 16x and -9x to make 7x, so 7x-15=13, then you would add 15 to 13, and your new equation would be 7x=28. THen divide 28 by7 and your answer is 4

A 185-pound person burns 260 calories during a soccer game. Find the number of calories that a 250-pound person would burn durin

Olin [163]

Answer: The answer to this problem is 178 calories.

Step-by-step explanation:

To calculate the answer, simply get the percentage of calories a person would burn during exercise (I am using a calculator BTW).

185 / 260 = 0.711538462

Then, calculate 71.1538462% of 250 pounds.

250 * 0.711538462 = 177.884616

Finally, round up your answer. 177.884616 rounded up is 178.
