Answer:
m<A = 75 and m<B = 105.
Step-by-step explanation:
To find the two angles, we first take 180 (because supplementary angles are two angles that add up to 180) and we divide it by 2 to get 90. Then we take 30 degrees and divide that by 2 to get 15. You add 15 degrees to measure B and subtract 15 degrees to measure A. So then you get m<A = 90 - 15 = 75 and m<B = 90 + 15 = 105.
Answer:
48 months
Step-by-step explanation:
Brandon estimates that he will need $18,000 each year to attend a 4-year college.
His family can pay $5,000 a year and he can get a student loan for $10,000 each year.
This means that, each year, $15000 out of the $18000 has been covered. That is the sum of the money from his parents and the loan:
$5000 + $1000 = $15000
That means the amount he still needs to cover per year is:
$18000 - $15000 = $3000
In 4 years, he will need to cover:
4 * $3000 = $12000
He saves $250 a month. Therefore, the number of months he will need to save $12000 is:

He will need to save for 48 months to save the rest of the money he will need for College.
Answer:
x=5 or x=-5
Step-by-step explanation:
either one of those
x2−9=16
Step 1: Add 9 to both sides.
x2−9+9=16+9
x2=25
Step 2: Take square root.
x=±25
x=5 or x=−5
