Im not sure if i am understanding the question correctly...
If you are asking if Jama's mom is correct, then no. she is wrong. this is because
if you take the proportion, (is/of)=(%/100) you get (x/30)=(70/100). You then solve for x which in this case would be 21 students are wearing tennis shoes.
Hope this helps.
The first one is the only one that shows equivalent fractions
If correct brainliest please
Thank you and Your welcome

In order to have the variable by itself you have to add 20 to both sides. So your answer would be a=b+20. I hope this helps love! :)
All the angles should add up to 360°.
8x+10x+9+21x-12+90=360°
Group like terms together.
So,8x+10x+21x+9+90-12=360
39x+87=360
39x=360-87
39x=273
x=7
Answer:
nothing
Step-by-step explanation:
Loan payments are <em>linear in the loan amount</em> for a given rate and period, so the payments for loans of $2000 and $1000 sum to the amount of payments for a loan of $3000.
The only possible savings (or cost) might come from rounding to the nearest cent. (In any event, the final payment on each loan should make up for any differences due to rounding.)
