Vertical angles are the same measurement and are opposite each other.
Angle 3 is opposite angle 1 and would also be 130 degrees.
First equation:
y=10x+150
y=25x
10x+150=25x
15x=150
x=10
so, 10 weeks
EDIT:
how many dollars dey save? dunno
jkkkkk
For John
150+10(10)=
150+100=
250
For Erin
They both equal
Answer:
I think the answer is 7.5, because of this equation: 2x-5=10
Multiply 12 x 12 which is 144. And then you divide that by 6 and you get 24
Step-by-step explanation:
to solve for a,
f(-1) = 5
a(-1)^2 + 1 = 5
a + 1 = 5, so a=4
