Michael was asked to pick a number between 0 and 50 for a contest at school. The number he chose is less than 50 and is a multiple of 5 and 8. Select Michael's number. A) 24 B) 30 C) 32 D) 40

D) 40

Step-by-step explanation:

First, identify what you know:

1) Michael is directed to pick a number between 1 and 50

2) Michael picks a number that is less than 50

3) The number chosen, is a multiple of 5 and 8

A multiple is a number that can be divided by another number without a remainder. What number can be divided by 5 and 8 without having a remainder?

40/5 = 8

40/8 = 5

Michael chose 40!!

x=

Step-by-step explanation:

Step 1- Distribute into the parenthesis.

(3)5x+(3)1-3x=2+(-3)3x+(-3)1

Step 2- Multiply.

15x+3-3x= 2-9x-3

Step 3- Add common variables.

(15x-3x)+3=(2-3)-9x

12x+3=-1-9x

Step 4- Add 9x to both sides.

12x+3= -1-9x

+9x         +9x

21x+3= -1

Step 5- Subtract 3 to both sides.

21x+3= -1

     -3   -3

21x= -4

Step 6- Divide both sides by 21.

21x= -4

21    21
