Answer:

Mirandah added 5x and 9y, which she shouldn't do because one is y and the other is x, meaning they don't match.

There is no simplifying the equation. It should stay 5x + 9y - 4

If wrong, I apologize, but this should be correct.

In a volcano, erupting lava flows continuously through a tube system about 20 kilometers to the sea. Assume a lava flow of 0.5 k

butalik [34]

Answer:

40 hours

Step-by-step explanation:

Lets take "x" as the # of hours it takes the lava to reach the sea

since there is a lava flow of 0.5 kilos per hour

we will multiply "x" with 0.5

0.5x

now the tube system is 20 kilometers long

this means that at a rate of 0.5 kilos per hour the lava will reach the sea once it is 20 kilometers deep

0.5x=20

divide "0.5" by both sides to eliminate the coefficient

$\frac{0.5x}{0.5} =\frac{20}{0.5}$

x=40

it will take 40 hours for the lava to reach the sea

Hope this helps!

Simplify using the distributive property.<br>8(y + 12)<br>8y=12<br>20y<br>20 - y<br>8y + 96

My name is Ann [436]

Answer:

Correct choice is D). 8y + 96.

Step-by-step explanation:

Given expression is $8\left(y+12\right)$ .

Now question says to simplify that expression using distributive property then find the correct matching choice from the given choices:

A). 8y=12

B). 20y

C). 20 - y

D). 8y + 96

So let's distribute 8 by using distributive property

$a\left(b+c\right)=a\left(b\right)+a\left(c\right)$

$8\left(y+12\right)=8\left(y\right)+8\left(12\right)$

$8\left(y+12\right)=8y+96$

Hence correct choice is D). 8y + 96.
