Answer:

1 fancy 15 plain

Step-by-step explanation:

F + P = 16

15F +10P = 165

Miltiplu the 1st by -10:

-10F -10P = -160

15F + 10P = 165

Add both (10p is cancelled)

5F = 5

F =1

16-1 = 15 (15plain)

15 x10 =150

1x15 =15

150 +15 = 165

Answer:

Step-by-step explanation:

hello

$2x+2=6 2x+2-2=6-2 \ \ \ substract \ \ 2\\ 2x = 4 \dfrac{2x}{2}=x=\dfrac{4}{2}=2 \ \ \ divide \ \ by \ \ 2\\$

so the solution is 2

$5x+4=8 5x+4-4=8-4 \ \ \ substract \ \ 4\\ 5x = 4 \dfrac{5x}{5}=x =\dfrac{4}{5} \ \ \ divide \ \ by \ \ 5$

so the solution is 4/5

hope this helps

Can someone please explain step by step on how I subtract fractions like for an a example!

kotykmax [81]

Keep the denominators the same and subtract the numerators. So for example in your example:

7/8 - 3/8

Leave the 8 alone. Subtract 3 from 7.

7 - 3 = 4

So answer is:

4/8

Sometimes they may have to simplify the answer, and in this case, 4/8 could be simplified to 1/2

Did you not include D or finish writing D since the first three are not right. If one of the possible answers is that they are alternate exterior angles or the same degrees, that would be the answer.
