Answer 17

"The product of a number and the sum of one and four is 40. Find the number." You have ONE unknown number here. Please choose a letter of the alphabet to represent it.

Answer 18

huh? @mathmale

Answer 19

Answer 20

is it 36 @mathmale

Answer 21

This being Algebra, we need to represent unknowns by letters.

We could choose x to represent the unknown number.
"The product of a number and the sum of one and four is 40. Find the number."

This becomes x ( 1 + 4 ) = 40.

Because of order of operations rules, we must do the operation within parentheses first.

would you do that now, please, and rewrite the equation in its new form?

Answer 22

x ( ? )=40

Answer 23

8

Answer 24

8 times 5 equal 40

Answer 25

so can the x represent 5

Answer 26

No. The x represents the unknown number. Thus, x(5)=40, or, better, 5x=40.

How would you solve that for x?

Answer 27

Sorry, but I've got to go. Perhaps we could continue this discussion later.

Answer 28

by simplifying?
