Answer:

C. She did not follow order of operations.

Step-by-step explanation:

Order of operations says you always have to multiply before you add when solving an equation, unless there are parentheses. Meaning that she should have multiplied -9 and 2/5 first before adding -18, instead of adding -9 and -18 first.

Ray is buying some ginger roots to brew some fresh ginger ale. The price of the ginger root is g, and Ray has a coupon for 10% o
kondaur [170]

Step-by-step explanation:

Comparision: Let say you buy chocolate that cost $1. And there was luckily a coupon, for 10% off.

That means after applying the coupon, you will only pay 90% of the original price. Which is

0.9(1) = 0.9

which equals 90 cents.

So let go back to this problem and apply similar thinking.

The price of the original root is g, so for the original price column, check the 3rd cell, g.

Use our comparision problem, by applying the coupon to the chocolate, you will save

1 - 0.9 = 0.1

which is 1/10 of the original price.

In this equation, we can represent this as 0.1g.

So for the second column, shade in 5th cell, 0.1g.

The price would be

(0.9)1 = 0.9

So our equation for this equation will be

0.9g.

So for third column, shade in 1st cell, 0.9g.

ANYONE PLEASE HELP!!
lapo4ka [179]

Answer:

A

Step-by-step explanation:

Corresponding angles are angles that you can follow down the transversal and they will land in the same spot on the other parallel line.  Look at angle 8.  It is the bottom left angle in the group of 4 angles around it.  If you slide it to the left it would land right on top of angle 4 which is also in the bottom left of its group of 4 angles.

You can do the same thing taking angle 8 down to angle 12.
