1) Put all equations together and add them up to equal 180. Triangle's angles add up to 180°
EX) (x+10)+(3x-5)+x=180
2)Combine like terms.
EX) (5x+5)=180
3) Subtract 5 to both sides
EX) 5x=175
4) Divide both sides by 5.
EX) x=35
Answer:
your answer is for sure D but I think C is also the answer
Step-by-step explanation:
Additive relationship are two quantities can be expressed as related to each other through addition. It can be written as y = x + a, where y is related to x through the addition of a constant, a. The value for a may be positive or negative.
Changing the inequality signs would ensure that the signs on the solution would also be reversed
<h3>How to determine the true statement?</h3>
The system of inequality is given as:
When the inequality signs are reversed, we have the following system of equations
Changing the inequality signs would ensure that the opposite region of the initial system of inequality is shaded, and the signs on the solution would also be reversed

53.96+0.17x =57.96+0.12x
0.17x-0.12x=57.96-53.96
0.05x=4.00
x=80 mi
Answer:
Step-by-step explanation:
Ello again!
Ok so you would turn the percent into a decimal again 8% ↠ 0.8
then you would multiply the decimal and money 90 × 0.8 = 72
