Answer:
x=14
y=24
Step-by-step explanation:
4y+42=8y-54
4y-8y=54-42
-4y/4=96/-4
y=24
solving for x
5x-28=7x-56
5x-7x=-56+28
-2x/-2=-28/-2
x=14
Answer:
The rate of change will be the same for all years.
Step-by-step explanation:
As it is mentioned in the question, that the rate of change is 7%.
And as we know that
= I (1 + R)^T
where
I = Initial amount
R = Rate of growth,
And T = Time.
So in the given case, the rate is 0.07, or 7% while on the other hand the growth RATE remains constant and the growing amount would be increased each year.
Therefore the rate of change would be the same for all the year
Answer:
C
Step-by-step explanation:
∠2 and ∠7 are alternate interior angles
alternate interior angles are congruent meaning ∠2 ≅ ∠7
we have ∠2 = 2x + 7 and ∠7 = 3x - 13
hence, 2x + 7 = 3x - 13
==> add 13 to both sides
2x + 20 = 3x
==> subtract 2x from both sides
20 = x
now to find the measure of ∠7 we plug in the value of x
∠7 = 3x - 13
==> plug in x = 20
∠7 = 3(20) - 13
==> multiply 3 and 20
∠7 = 60 - 13
==> subtract 13 from 60
∠7 = 47
