Test Review Equation

Terri has bags of popcorn for $7.50 each & she already has $120. Write an expression for the situation.

• 7.5x = 120

• 7.5x + 120

• 7.5x + 120 = 90

• 7.5/x = 120

• 6x - y = 162

Solve the following

7x > 2x + 4

• x > 4/5

• x < 4/5

• x > 5

• x > 4

Solve the following equation

2x - 5 = 19 - 6x

• x = 8/14

• x = 14/8

• x = 8

• x = 14

What is the first step in the following equation

• give up

• Distribute

Samuel bought 3 tires for $79.95 each and some rims for $59 each. He spent a total of $534.85. Which equation could be used to find the number of rims, r, Samuel bought?

• 3(79.95) - 59r = 534.85
• 79.95r - 59(3) = 534.85
• 3(79.95) + 59r = 534.85
• 79.95r + 59(3) = 534.85

What is the first step to solve this equation 2x + 11 = 23?

• Add 3 to both sides
• Subtract 11 from both sides
• Add 1 to both sides
• Divide 3 on both sides

Which equation matches the following situation? 331 students went on a field trip. Six buses were filled and 7 students traveled in cars. How many students were in each bus?

• n= # of students in each bus; 6n + 7 =331
• n=# of buses; 6n + 7 =331
• n= # of students in each bus; 6 + 7n =331
• n= # of students in each bus; 6n - 7 =331

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

• n=total cost pencils; 7n+10=24
• n=cost of 1 pencil; 7n-10=24
• n=cost of 1 pencil; 7n+10=24
• n=cost of 1 pencil; -7n-10=24

The space club is having some posters printed. The printer charges $250 plus $2 per poster. How can I figure out how many posters I could print for $1,000?

• 250x + 2 = 1000
• 1000 + 2x = 250
• 250 - 2x = 1000
• 2x + 250 = 1000
