5. chan is in a running club and needs to run at least 500 miles in a year to
earn the gold level of achievement. he is presently at 220 miles. which
inequality can be used to determine the additional number of miles he
can run and earn gold?
a. x + 220 < 500
b. x + 220 > 500
c. x + 500 > 220
0 x + 500 < 220

B

Step-by-step explanation:

He needs to run at least 500 miles, presently at 220 miles. Since x represents the gap between 220 and 500 (or greater), C and D are ruled out. A is incorrect because he needs to run at least 500 miles. So, the answer is B.

if a = 1,   and b = 2, then the answer is 47.99999999. if you round that to the nearest whole number, the answer is 48.
