Answer:
set both of them equal to each other:
8x - 8° = 5x + 25°
subtract 5x by both sides of the equations and it becomes:
3x-8° = 25°
now add 8° both sides:
3x = 33°
divide three by both sides:
x = 11°
now thats done to find B:
plug your x value in the B equation:
5x + 25°
5(11) +25°
55 +25°
not sure if you can add here sorry :(. I hope this helped so far :)
Answer: y=12.287
Step-by-step explanation:
Answer:
Last year the cost was $28.
This year the cost is $36.
$36 - $28 = $8
Percent of increase = amount of increase ÷ original amount
$8/$28 = $0.286
$0.286 · 100 = 28.6%
There has been a 28.6% of change in the cost.
Y² + 8y + 15
since 8 and fifteen are positive, that means your factors are going to be positive
(y + )(y + )
What are the factors of 15 that add up to 8?
Y = 5 x 3 + 8
y = 15 + 8
y = 23
