Rusty burns 6 calories per minute swimming and 10 calories per minute jogging. in the morning rusty burns 175 calories walking and swims for x minutes. in the afternoon rusty will jog for x minutes. how many minutes must he jog to burn at least as many calories y in the afternoon as he did in the morning

Since rusty can burn 10 calories per minute by jogging. And he burn 175 calories by walking and swimming in the morning. So to solve the time he needs to jog to burn the same calories,

175 cal = ( 10 cal/min) ( x min)

X min = 175 cal / ( 10 cal/ min)

X min = 17.5 min

a.

step-by-step explanation:

step 1 distribute 2 to every term in the parentheses

step 2 add 10 on both sides of the equal sign

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
