Question

A pedicab travels 5 miles to pick up a customer. Then, the pedicab travels an average of 12 miles per hour for the entire job. Which equation shows that the pedicab traveled a total of 14 miles?

5(14) + h = 12.
5 + 12h = 14
5h + 14 = 12
12(5 + h) = 14











-12 (x + 7) = 60
x = -12
x = -2
x = 2
x = 12









Debbie borrows $45, and then pays $5 back each week. She currently owes $20. What will the variable stand for?
her total debt
how much she has paid back
how many weeks have passed
her account balance






Michael has 27 keys, which is 3 times as many as Rachel. Rachel has 8 more keys than Ann. How many keys does Ann have?
Ann has 1 key.
Ann has 17 keys.
Ann has 73 keys
Ann has 89 keys.






What is the first step you would take to solve the equation 5x - 12 = -20?
Divide 5x and -20 by 5.
Add 20 to both sides.
Multiply 12 by 1/5
Add 12 to both sides.

Answer 1

1. Let h be the number of hours that Pedicab traveled.

Total distance Pedicab traveled = 14 miles.

The distance Pedicab traveled to pick up the first customer = 5 miles.

So, 5 + 12h = 14.

2. -12(x + 7) = 60

Divide both sides by -12,

x + 7 = -5

Subtract 7 from both sides.

x = -5 - 7

x = -12

3. Total money borrowed by Debbie = 45

Money repaid by her each week = 5

Money that she owes currently = 20

So, 45 - 5t = 20, here the variable t stands for the number of weeks passed.

4. Number of keys Michael has = 27

= 3(Number of keys Rachel has)

So, Number of keys Rachel has = 27/3 = 9

Number of keys Rachel has = 8 + Number of keys Ann has

So, Number of keys Ann has = 9 - 8 = 1

Hence, Ann has only one key.

5. 5x - 12 = -20

To solve for x, we need to isolate it.

So, for the first step, we have to add 12 to both sides.
