Answer:
150
Step-by-step explanation:
3 times 50 equal 150
If this is just an expression, then all you have to do is combine like terms, or groups of numbers and variables that have the same variable.
When simplified, you get the equation
-12+ 16r or
-18+6+3r+13r=16r-12
Answer:
40,45,95
Step-by-step explanation:
The sum of the angles of a triangle are 180
2x+10 + 3x + 8x-25 = 180
Combine like terms
13x - 15 = 180
Add 15 to each side
13x - 15+15 =180 +15
13x = 195
Divide by 13
13x/13 = 195/13
x =15
The angles are
2x+10 = 2(15)+10 = 30+10 = 40
3x = 3(15) = 45
8x-25 = 8(15) -25 = 120-25 = 95
