If it takes a cheetah 3 hr. to run 135 mi. over flat ground, how fast is it running? A. 40 mph
B. 45 mph
C. 50 mph
D. 55 mph

C: 45 mph

All I did was divide 3 and 135 to get the answer

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
