All the angles in a triangle equal 180 degrees so 128 + (5x+10) + 9x = 180
Group the like values to get 138 + 14x = 180
Subtract 138 from 180 to get 14x = 42
Divide 42 by 14 to get x = 3
Therefore x = 3
Answer:
1.5+1.7/2=1.6
Step-by-step explanation:
Answer:
x = 7
Step-by-step explanation:
Expand 3x+2(x-5)=25 which looks like
3x+2x-10=25
Add similar elements: ( 3x+2x = 5x)
5x-10=25
Add 10 to both sides
5x-10+10 = 25 + 10
Simplfy
5x = 35
Divide both sides by 5
5x ÷ 5 = 35 ÷ 5
Simplfy:
x = 7
have a wonderful day
Add three to the product of 4 times twelve
The answer will be 2. the gcf of the equation is 2 because 2 goes into 10 by 5 and into 4 by 2 leaving you with 2(5b^2+2a^3).
