Answer:
The answer is D
Step-by-step explanation:
We know that a triangle adds up to 180 degrees.
<u>Solve for x:</u>
Combine like terms.
2x + 3x - 10 + 50 = 180
Subtract 40 on both sides.
5x + 40 = 180
-40 -40
Divide both sides by 5.
5x = 140
---- ----
5 5
And you get a solution of:
x = 28
<u>Check:</u>
Substitute 28 into x and multiply 28 by the number outside of the parentheses.
2(28) + 3(28) - 10 + 50 = 180
Add/Subtract from left to right.
56 + 84 - 10 + 50 = 180
Add them together.
140 + 40 = 180
And you get 180!
180 = 180
Answer:
blue jar=27+x
red jar=x
total=193
x+x+27=193
2x=193-27
2x=166
x=83
blue jar=110 coins
red jar=83
