Answer:
e°=100°
Step-by-step explanation:
Sum of angles in a triangle= 180°
70°+30°+x°=180°
100°+x=180
Collect like terms
x°=180-100
x°=80°
e° is an exterior angle
exterior angle =180- interior angle
180°- x°
180°- 80°
=100°
e°=100°

Answer:
x²+12x+11=(3x+21)
Step-by-step explanation:
x²+10x–11=(x–1) (+2x)
x²+12x–11=(3x–1) (+22)
x²+12x+11=(3x+21)

Answer:
B) 5x/x +3/x
Step-by-step explanation:
Choice B is the only choice showing a correct denominator: x.
Here, the "first step" is apparently to divide <em>each term</em> by the denominator. This is reasonable when the denominator is only one term.
(I'd say the first step is to divide the <em>first term</em> by the first term of the denominator.)
Answer:
<h2>y = 20</h2>
Step-by-step explanation:
<u>First of all cross multiply</u>
That's
7y = 140
<u>Divide both sides by 7</u>
That's
We have the final answer as
<h3>y = 20</h3>
