Rafael is choosing between two exercise routines. In Routine #1, he does only running, burning 15.5 calories per minute. In Routine #2, he burns 19 calories walking. He then runs at a rate that burns 10.75 calories per minute. For what amounts of time spent running will Routine #1 burn more calories than Routine #2? Use t for the number of minutes spent running, and solve your inequality for t.

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

37 = ending with 7

unit's digit in the cube..3

56 = ending with 6

unit's digit in the cube..2

133 = ending with

unit's digit in the cube..7
