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.

Simplify. (-2u?+u-3)+(4u²+7u+5)

Pavlova-9 [17]

Answer:

$2u^2+8u+2$

Step-by-step explanation:

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

$\blacksquare$ Remove parentheses:

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

$\blacksquare$ Combine like terms:

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

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

$\longmapsto$ $\:u+7u=8u$

$\longmapsto$ $-3+5=2$

$\leadsto$ $2u^2+8u+2$
