Answer:
$11
Step-by-step explanation:
we can set up an equation to answer the question. a first payment of 28 plus some amount monthly for a year equals 160. so,
12x + 28 = 160
subtract 28 from both sides
12x = 132
divide by 12 and we get our answer
x = 11
D. 7x2+3y2+4x+4x2−4y+2 is your correct answer
-3x² + 3y² + 4x + 4x² - 4y + 2
Add like terms.
x² + 3y² + 4x - 4y + 2
So the answer is D.
Answer:
3.5
Step-by-step explanation:
just took the quiz
the answer is 12 since the sum of the two angles has to equal 180.
first you do
5x+5+115=180
combine like terms
5x+120=180
subtract 120
5x=60
then divide by 5
x=12
