26 x 25 x 24 x 10 x 9 x 8 = 11,232,000
Answer: 11,232,000
Answer:
<u>a = 24</u>
Step-by-step explanation:
a - 1.5 = 22.5
a = 24
you can plug it into the other 2 to make sure it is right my brain hurts so i won't.
Have a nice day! :) and btw people will think it is a scam because 2 answers are allowed right so the points split in half and the person answering will only get 10 points
Answer:
x= -8 , y = 5
x= 25/4 , y = 1/4
Step-by-step explanation:
substitute first eqn into the second eqn:
(7 - 3y)^2 -y^2 = 39
49 - 42y + 9y^2 - y^2 = 39
8y^2 - 42y +10 =0
4y^2 - 21y + 5 = 0
(4y-1) (y-5) = 0
y= 1/4 , 5
when y=1/4
x = 7- 3/4
=25/4
when y= 5
x = 7- 15
= -8
∡3 and ∡7 are corresponding angles, so m(∡3) = m(∡7) = 115°
∡7 and ∡5 are verically opposite angles, so m(∡7) = m(∡5) = 115°
