Answer:

D, $100.00

Step-by-step explanation:

1. Find out how much what each percent is out of 400

Food - 20% of 400 = 80

Entertainment - 18% of 400 = 72

Savings - 15% of 400 = 60

Misc - 12% of 400 = 48

Clothes - 10% of 400 = 40

2. Subtract the money from 400

400 - 80 = 320

320 - 72 = 248

248 - 60 = 188

188 - 48 = 140

140 - 40 = 100

3. All we have left is 100, so he spent $100 dollars on rent.

solong [7]

Answer:

There are many combinations based on the number you chose to subtract from both sides.

Step-by-step explanation:

Let the number be x.

According to the question,

3 x+7 > 4 x

We get, 3 x+1=4 x-6, after subtracting 6 from both sides.

3 x+1=4 x-6

4 x- 3 x=6+1

x=7

You will get the same answer if you subtract 3 x or 7 or any other number from both sides.

Thank you!

Answer:

x = 9

m Angle B = 54

m Angle E = 54

Step-by-step explanation:

As m Angle B and m Angle E are congruent,

5x + 9 = 7x - 9

-2x = - 18

x = 9

m Angle B = 5x + 9 = 54

m Angle B = m Angle E

Therefore, m Angle E = 54
