13 less than 8R leaves 43

8(7)-13=43

R= 7

Step-by-step explanation:

13 less than 8R leaves 43.

R is the unknown.

This expression can be in an equation.

8R-13= 43

Carry over the like terms. Carry over the -13 and make R the subject.

8R= 43+13

8R= 56

R= 56/8

R= 7

To check if the answer was correct, replace the unknown which is R with the value of what it is in brackets. Remember brackets mean to multiply.

8(7)-13= 43

56-13= 43

Therefore the answer is 7

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
