Zach and Ginny are building model cars. Ginny's car is 2 more than 3 times the length of Zach's car. The sum of the lengths of both cars is 30 inches. Write an equation to determine the lengths of Zach's and Ginny's cars.
3x + 2 = 30
x + 2 + 3x = 30
2x + 3 = 30
x + 2x + 3 = 30

x + 2 + 3x = 30

Step-by-step explanation:

Since Ginny's car is 2 more than 3 times the length of Zach's car, lets say Zach's car is x. 2 more means (+2) and three times means (3x) so Then Ginny's car would be 3x + 2.

If the sum of the lengths of both cars is 30 inches, add both cars.

x + 2 + 3x = 30

the difference between a number and 5 is -2.

step-by-step explanation:

notice that the equation you are given has -2 (negative 2) on the right side, not 2. when you subtract 5 from a number n, you are finding the difference between the number and 5.

the difference between a number and 5 is -2.
