Question

Make the mathematical expressions, then simplify. a) 3 times the sum of 6 and 5.​

Answer 1

Answer:

Three times is 3*. The "sum of a number and 6" is (X + 6), where X is the "number." So the first portion of the sentence is 3*(X + 6).

The "is" is essentially the equals sign, = and the result is = 5..

Putting it together:

3*(X+6) = 5

Solving,

3X + 18 = 5

3X = -13

x = -(13/3)

Check the number:

3*(-(13/3) + 6) = 5 ??

-13 + 18 = 5 ?

5 = 5 Yes
