Answer:
7.1
Step-by-step explanation:
I'm not sure why you have two equal signs, so I'm just going to use the part before the second sign.
-4.5 = -0.5(x-7.1) -4.5
Add 4.5 to both sides -4.5 + 4.5 = -0.5(x-7.1) -4.5 + 4.5
0 = -0.5(x-7.1)
Multiply both side by -2 -2 * 0 = (-2)(-0.5)*(x-7.1)
0 = 1 * (x - 7.1)
0 = x - 7.1
Add 7.1 to both sides 0 + 7.1 = x - 7.1 + 7.1
7.1 = x
Answer:
D. The numbers distance from zero in the number line.
Step-by-step explanation:
Answer:
A = 55
B = 60
Step-by-step explanation:
We know that 55+ b+ other angle = 180 since they make a straight line
The other angle = 65 since they are alternate interior angles
55+ B+ 65 = 180
Combine like terms
120 + B = 180
B = 60
A + B + 65 = 180 interior angles of a triangle must equal 180 degrees
A +60+ 65 =180
Combine like terms
A +125 = 180
A = 55
