WRITE AN EQUATION 331 students went on a field trip. Six buses were filled and 7 students traveled in cars. How many students were in each bus?

6 x + 7 = 331 6x+7=331 6 x + 7 = 3 3 1

7 x + 6 = 331 7x+6=331 7 x + 6 = 3 3 1

13 x = 331 13x=331 1 3 x = 3 3 1

331 − 7 = 6 x 331-7=6x 3 3 1 − 7 = 6 x

WRITE AN EQUATION Aliyah had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?

7 x + 10 = 24 7x+10=24 7 x + 1 0 = 2 4

24 − 10 = 7 x 24-10=7x 2 4 − 1 0 = 7 x

7 x − 24 = 10 7x-24=10 7 x − 2 4 = 1 0

10 + x = 14 10+x=14 1 0 + x = 1 4

Laura spent a $50.00 at the store. She bought a purse for$15 and used the rest of the money to buy 10 bottles of nail polish. Which equation models the problem?

10 n + 15 = 50 10n\ +\ 15\ =\ 50 1 0 n + 1 5 = 5 0

25 n = 50 25n\ =\ 50 2 5 n = 5 0

50 − 15 p = 10 50\ -\ 15p\ =\ 10 5 0 − 1 5 p = 1 0

15 p + 10 = 50 15p\ +\ 10\ =\ 50 1 5 p + 1 0 = 5 0

WRITE AN EQUATION Aliyah had $24 to spend on seven pencils. After buying them she had $10. How much did each pencil cost?

10 + 7 x = 24 10+7x=24 1 0 + 7 x = 2 4

24 − 10 = 7 x 24-10=7x 2 4 − 1 0 = 7 x

24 + 7 x = 10 24+7x=10 2 4 + 7 x = 1 0

10 + x = 14 10+x=14 1 0 + x = 1 4

Scott works on cars. He charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie's car bill was $63.

7 x + 35 = 63 7x+35=63 7 x + 3 5 = 6 3

7 x − 35 = 63 7x-35=63 7 x − 3 5 = 6 3

35 x + 7 = 63 35x+7=63 3 5 x + 7 = 6 3

Penelope is going to the carnival to ride the rides. It costs $20 to get into the carnival and ride tickets are $0.50 each. Write an equation that represents this scenario if she spends $35 in all.

0.50 x + 20 = 35 0.50x+20=35 0 . 5 0 x + 2 0 = 3 5

0.50 x = 35 0.50x=35 0 . 5 0 x = 3 5

0.50 + 20 x = 35 0.50+20x=35 0 . 5 0 + 2 0 x = 3 5

0.50 x − 20 = 35 0.50x-20=35 0 . 5 0 x − 2 0 = 3 5

WRITE AN EQUATION Jill sold half of her comic books and then got sixteen more. She now has 36. With how many did she begin?

x 2 + 16 = 36 \frac{x}{2}+16=36 2 x + 1 6 = 3 6

x 2 = 36 + 16 \frac{x}{2}=36+16 2 x = 3 6 + 1 6

36 + 16 = x 36+16=x 3 6 + 1 6 = x

x 2 − 16 = 36 \frac{x}{2}-16=36 2 x − 1 6 = 3 6

What is the difference between an expression and equation?

Expressions do not have an equal sign and equations do have an equal sign

Expressions have an equal sign and equations do not have an equal sign

Expressions do not have variables and equations have variables
