The word "is" stands for what mathematical symbol? (Type only the SYMBOL.)

At Joe's Clown Car Rental Agency, renting a car costs $35 plus $0.75 for every mile it is driven.  What is an equation that can be used to find the number of miles, m, a vehicle was driven, if the total rental charge was $222.50?

• 222.5 = m(35 + 0.75)

• 222.5 = 35 + 0.75m

• 222.5 = 0.75 + 35m

• 222.5 = 0.75(m + 35)

Dexter's Gym charges a one-time registration fee of $40 and $20 each month. The total fee after x months is $340. Which equation models this situation?

• 40x + 20 = 340

• 20x - 40 = 340

• 20 + 340 = 40x

Scott's Automotive charges $35 for each car plus $7 per hour. Write an equation that represents this scenario if Kylie was charged $63.

• 35x + 7 = 63

• 7x = 63

• 7x + 35 = 63

The world's two highest dams are both in Tajikistan. The Rogun Dam is 35 meters taller than the Nurek Dam. Together they are 635 meters tall. Which equation can be used to determine the height of Nurek Dam?

• 35x + 2 = 635

• 2x - 35 = 635

• 2x + 35 = 635

• x + 35 = 635

Translate the sentence into an equation:

Four more than six times a number is 18.

• 4x + 6 = 18

• 4x + 6 = 18

• 6x + 4 = 18

Translate:

Three times the sum of a number and 7 is equivalent to 57.

• 3x + 7 = 57

• 3(x + 7) = 57

• 7x + 3 = 57

• 7(x + 3) = 57

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.

• .50x + 20 = 35

• .50x = 35

• .50 + 20x = 35 

• .50x - 20 = 35
