Answer:
No they are not equal;
a = -13
Step-by-step explanation:
Here, we want to find the value of a
We are gong to use the ratio given
That will be;
a + 3/ 7 + a = 4/5
5(a + 3) = 4(7 + a)
15 + 3a = 28 + 4a
4a - 3a = 15-28
a = -13
Answer:

<span>22c² and 30c³
2*22c² and 2*15c²c
We see that these monomials have in common 2c²,
so the greatest common factor is 2c².

Answer:
a =18
Step-by-step explanation:
The two angles are vertical angles and vertical angles are equal
6a +11 = 2a+83
Subtract 2a from each side
6a-2a +11 = 2a-2a+83
4a +11 =83
Subtract 11 from each side
4a +11 -11 = 83-11
4a = 72
divide each side by 4
4a/4 = 72/4
a =18
