Working together, 5 friends collected 15 5/8 bags of food for the homeless. On average, how many bags of food did each friend co
Effectus [21]

15 5/8 divided by 5

First, we turn the 15 5/8 to a mixed number: 8 * 15 + 5 = 125/8

125/8 divided by 5/1 (which is equal to 5)

Next, we do Keep Change Flip.

Keep 125/8 the same, change the division to multiplication, and turn the 5/1 to 1/5.

1 * 125 = 125

8 * 5 = 40

Then, we get 125/40 = 3 5/40 BUT WAIT

We can reduce it once more! Divide 40 by 5

Each friend collected 3 1/8 bags of food.

Pavlova-9 [17]

Answer:

2u^2+8u+2

Step-by-step explanation:

\left(-2u^2+u-3\right)+\left(4u^2+7u+5\right)

\blacksquare <u>Remove parentheses:</u>

\longmapsto -2u^2+u-3+4u^2+7u+5

\blacksquare <u>Combine like terms:</u>

-2u^2+4u^2+u+7u-3+5

\longmapsto -2u^2+4u^2=2u^2

\longmapsto\:u+7u=8u

\longmapsto -3+5=2

\leadsto 2u^2+8u+2
