Answer 4

here are the answer choices.
a 90.
b. 180.
c. 19.
d. 25

Answer 5

So you know that
m<M + m<V = 90
You also know that m<M = 3x - 14, and m<V = 2x + 9,
so replace m<M and m<V in
m<M + m<V = 90 by the expressions in x and solve for x.

Answer 6

can you just give me the answer please

Answer 7

That wouldn't be any fun for you. The whole fun in math is to solve a problem and feel great that you did it. I'll guide you step by step.

Answer 8

m<M + m<V = 90
m<M = 3x - 14, and m<V = 2x + 9
Do the substitutions to get:
3x - 14 + 2x + 9 = 90

Answer 9

Now combine like terms on left side

Answer 10

5x - 5 = 90
Now add 5 to both sides.
Then divide both sides by 5.
What do you get for x?

Answer 11

5x-5=90
+5 +5
10x=90
/5 /5
2 18 and then what?

Answer 12

oh wait it supposed to be 95 isnt it?

Answer 13

Wait, 90 + 5 = 95, not 90.
Also, on the left side, you have 5x - 5. Whan you add 5 to it, you get 5x, not 10x.

5x - 5 = 90
Add 5 to both sides:
5x = 95
Now divide both sides by 5 to get x.

Answer 14

thank you so much. i got 19 :)
