Answer:
$9.35
Step-by-step explanation:
Simply start by adding up the total cost of each item.
$26.38 + $78.92 + $34.50
= $140.25
The total is $140.25
If 15 students want to split the cost, you’ll need to divide it by 15.
$140.25 divided by 15 = $9.35
So the total for each student is $9.35
Answer:
Bigger size / smaller size = 40
Step-by-step explanation:
Notice that we
36 / (9/10) = 30 / (3/4) = 40
Therefore the proportion model would be
Bigger size / smaller size = 40
The answer is 4n-25
4 times n is 4 n
and 25 decreased or subtracted from the 4n
thus the answer is 4n-25

Answer:
(x -1)(12x +13)
Step-by-step explanation:
You are looking to rewrite the middle term as the sum of terms that have factors of (12)(-13) that have a total of +1. Those factors are -12 and +13, so the expression you are factoring by grouping is ...
12x^2 +13x -12x -13
= x(12x +13) -1(12x +13)
= (x -1)(12x +13)
