A cheetahs sprinting speed is 61 miles per hour less than three times a zebras running speed. A cheetah can sprint 68 miles per hour. Find the zebras running speed

Answers

Let Cheetah speed be c, let Zebra speed be z

Cheetah speed is (=) 61 miles per hour less than 3 * zebra running speed.

c = 3z - 61.

c = 68 miles/hour

c = 3z - 61

68 = 3z - 61

3z - 61 = 68

3z = 68 + 61

3z = 129

z = 129/3

z = 43

Zebra speed is 43 miles per hour

A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.

We have been given that Kareem has 4 sweaters, 6 shirts, and 3 pairs of slacks.

To determine the number of distinct outfits, each consisting of a sweater, a shirt, and a pair of slacks, can Kareem select.

Add 4 sweaters and 6 shirts and that should add up to 10 in total, then times 10 sweaters/shirts by 3 slacks to get 30 as a grand total.

Therefore, the number of the distinct outfit is 30 each consisting of a sweater, a shirt, and a pair of slacks that can Kareem select.

Solve equation
2/3=18/x+5

Answers

Subtract 5 from 2/3 to get -4 and 1/3 or -13/3
-13/3=18/x
Multiply both sides by x to get rid of it from the 18/x
-13/3x=18
Multiply both sides by 3 to get rid of the fraction
-13x=54
Divide -13 from 54
x=-4.1538
