Answer:
A and B
Step-by-step explanation:
A) Collect like terms
0=0
B) Collect like terms
0=0
A and B both correct
I can’t see the exact numbers because the pic is blurry but here’s how to solve it.
The three angles in a triangle always add up to 180. So subtract the angle that’s given and you’ll have the sum of the two other angles. Since it’s an equilateral triangle, the other two angles are the same.
So write the equation 2(whatever the angle is) = the number you get when you do 180-the given angle
For example (I’m not sure these numbers are right because the pic is blurry)
2(9x+7)=114
Then you would solve for x and once you get x, plug it into the angle expression 9x+ 7 or whatever to get the angle measure.
8 is (7+4)/(7+4+5+9) = 11/25 = 0.44
9 is 5/(5+7) = 5/12 = 0.417 so I'm sorry I can't help with that one
Answer:
An important property of equations is one that states that you can add the same quantity to both sides of an equation and still maintain an equivalent equation. If you think of an equation as being like a balance scale, the quantities on each side of the equation are equal, or balanced.
