To get before the ten percent increase, you decrease the price by ten percent.
100 - 10 = 90

So to get 90 percent of 506, you multiply .90 by 506
.90 x 506 = 455.4

So the school's enrollment was $455.40 before the increase.

There are 28.35 grams in an ounce and 2.21 pounds in a kilogram. Miriam converted 7 kilograms to ounces, but her answer is not c
sergejj [24]

Answer: OPTION C.

Step-by-step explanation:

For this exercise it is important to remember the following:

1\ kilogram=1,000\ grams

Knowing this and based on the information provided in the exercise, you can make the conversion from kilograms to ounces. This is:

(7\ Kg)(\frac{1,000\ gr}{1\ Kg})(\frac{1\ oz}{28.35\ gr})=246.913\ oz

According to the exercise, Miriam's procedure was:

 (7\ Kg)(\frac{1,000\ gr}{1\ Kg})(\frac{28.35\ gr}{1\ oz})= 198,450\ oz

So you can identify that she made a mistake.

Notice that:

1. Miriaim multiplied correctly.

2. Butt the third fraction should be \frac{1\ oz}{28.35\ gr} and not \frac{28.35\ gr}{1\ oz}.

Find the values if x and y
SOVA2 [1]

Note that: (10x - 61) & (x + 10) are supplementary angles, and (10x-61) & (18y + 5) are vertical angles

10x - 61 + x + 10 = 180

Simplify

11x - 51 = 180

Isolate the x

11x - 51 (+51) = 180 (+51)

11x = 231

Divide 11 from both sides

11x/11 = 231/11

Divide

x = 21

180 = 18y + 5 + x + 10

180 = 18y + 5 + (21) + 10

Simplify

180 = 18y + 36

Subtract 36 from both sides

180 (-36) = 18y + 36 (-36)

144 = 18y

Divide 18 from both sides

144/18 = 18y/18

y = 144/18

y = 8

x = 21, y = 8 are your answers

hope this helps
