5th grade math. Correct answer will be marked brainliest.
dybincka [34]

Answer:

Trevor read 157.5 pages this week.

Step-by-step explanation:

Simple multiplication.

Multiply 5 by 5 first to get 25, carry the 2 on top and then multiply 3 by 5 to get 15, make sure to add 2 to get 17.  The first line should be 175.

Put a 0 on the last digit to solve for the next digit.  Multiply 4 by 5 to get 20, carry the 2 on top and then multiply 3 by 4 to get 12, make sure to add 2 to get 14.  The second line should be 1400.

Add the numbers up to get 1575, since there is one number behind the decimal, you should put a decimal in front of the last 5 for the answer in which it is 157.5.

How do you do a 3-step algebra equation?
Vlad1618 [11]
The goal of all algebra equations is to isolate the variable. In 3 step you should first make sure both variables are on the same side. To do that make sure you use the inverse.
For example:
6a + 9 = 3a + 15
because 3a is positive you're going to want to subtract it.
6a + 6 = 3a + 15
-3a         -3a
_______________
3a + 6 = 15

Now it's a 2 step equation and you solve it on from there.

John currently has $5000 in his savings
Alexus [3.1K]
John has $5,000 in his savings. That’s the total.
He has to give his sister $50 for her birthday.
He also spends $450 for his car payment.
We can easily put this into an equation.
50x-450=5000
Now we have to solve it.
50x-450=5000
-450 -450
50x=5000-450
50x=4550
50x/50=4550/50
x=91
So it will take 91 months to spend his $5,000.
