I believe you should do as much work as you can on each of these problems and only then ask for help. You'll almost always learn more by becoming involved in the thinking and problem solving you encounter here.
|x| + 5 = 13 reduces to |x| = 13, so x could be either -13 or +13.
You got it correct!
To get from 52 to 13, you divide by 4. And Vis versa, to get from 13 to 52, you multiply by 4. Considering they don't tell you which is the original, the only answer that is either 4 or 1/4 is F
Hope this helps!
After 10 weeks, the boys will have same amount in savings.
Step-by-step explanation:
Given,
Roberto already have $30.
Amount saved each week = $5
Let,
x be the number of weeks.
R(x) = 30+5x
Amount saved by Jack each week = $8
J(x) = 8x
For same amount, the functions will be equal.
R(x) = J(x)
Dividing both sides by 3
After 10 weeks, the boys will have same amount in savings.

Answer:
80% of the buttons were large.
Step-by-step explanation:
Recall that percentages are fractions.
We first need to find the total number of buttons that Eva bought
64 + 16 = 80
Then we need to divide 64 into 80 as a fraction of the whole (80 is our whole)
64 ÷ 80 = 0.8
To convert our decimal to a percentage, we must multiply it by 100.
0.8 * 100% = 80%
Therefore, 80% of the buttons were large.
