Step-by-step explanation:
he reads 2 pages per minute multiply 120 by 2
A quarter is .25 cents
A dime is .10cents
A nickel is .5cents
A penny is .01cent
3 quarters and 2 pennies=.77cents.
2 dimes and 1 nickel=.25cents

To solve this one-step equation you:
1. Substract 9 in both sides of the equation:
In this step is the mistake as Sara gets as result -4x=29 and the corret result of substract 9 in both sides of the equation is 5x=20.
2. Divide both sides of the equation into 5:
Then, the answer that Sara should found for the equation is x=4
Answer: 1, 3, 4, and 5 but stick with 1, 3, and 4
Step-by-step explanation:
just use a calculator to find 3, 4 is easy because red normally has more, and one is just an estimate
