variable. Then find the solution using guess-check-and-improve.
5 times a number, plus 1, is equal to 9 added to 3 times the number.
What is the number?
a. 5x + 1 = 9 + 3x, 4 c. 5x + 1 = 9 + 3x, 3
b. 5x − 1 = 9 + 3x, 5 d. 5x + 1 = 9 + 3x, 4.5

The solution of the equation  is  

So, option A is the correct option.

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
