Answer:
88 degrees
Step-by-step explanation:
First add up all of your degrees
85+ 87+ 83+ 88+ 91+ 87+ 95= 616
Then divide that amount by the amount of different degrees you had in the question. You have 7 different degrees, so you will divide by 7.
616/7= 88
And boom you have your answer
Y=x^2+3x+4
y-x=7
x^2+3x+4-x=7
x^2+2x+4=7
(factor) x^2+2x-3=0
(x+3)(x-1)=0
X= -3 and X=1
(Plug x in for y)
Y= 1^2+3(1)+4
Y=8
(Check your answer on the second equation)
8-1=7
7=7 (Which is the solution)
Answer:
12
Step-by-step explanation:
x will be the age of her younger brother
34 = 2x + 10
She is ten more than twice his age
34 = 2x + 10
- 10 - 10
Then she twice his age
24 = 2x
÷2 ÷2
So his age is 12
x = 12
Answer: 1+1 = 2 :)
