Can someone me with this: eighty, decreased by three times an number, is the same as five times the number, increased by eight. find the number? i'll mark you as brainless.

Eighty, decreased by three times an number, is the same as five times the number, increased by eight. Then the number is 9

Given that eighty, decreased by three times an number, is the same as five times the number, increased by eight

To find: the number

Let the required number be "a"

Let us break the given sentence

Eighty decreased by three times an number = five times the number increased by eight

Here "times" represents multiplication and "decreased" represents subtraction and "increased represents "addition"

80 - three times "a" = 5 times "a" + 8

80 - 3a = 5a + 8

80 - 8 = 5a + 3a

8a = 72

Thus the required number is 9

answer: 42

use a calculator to find that 845/73 = 11.575

the whole part of the answer is 11. multiply this by 73 to get 11*73 = 803.

subtract that result from 845 to get 845 - 803 = 42
