Answer:
8x+140=180
8x=40
x=5°
Step-by-step explanation:
Sum of angles in a straight line=180°
Answer:
The statement is true
Step-by-step explanation:
The denominators of the fractions are 3 and 4. The least common multiple of those numbers is 12, making the least common denominator 12.
x^2 = 800. Take the square root of each side.
x = √(800) and -√(800)
First things first, write out your equation without the substitution.
2x+ 2y= 10
Now, put in the substitution.
2x+ 2• 2= 10
Combine like terms.
2x+ 4= 10
Now that your equation it simplified, you need to reverse the problem and put everything on the other side.
2x+ 4= 10
- 4 - 4
2x = 6
2x=6
— —
2 2
X= 3
So the final answer is x=3
