5x+3y=58
5x-3y=22
(3y gets cancelled bc 3y-3y=0, then add 5x with 5x, so you're left with)
10x=80, (divide both sides by 10)
x=8
Now we look for y. So choose one formula from the two (let's say 5x + 3y=58)
Substitute x for 8 so it will look like---- 5(8)+3y=58
Multiply 5*8--- so you get -- 40+3y=58
Subtract 40 from both sides and you're left with 3y=18
divide both sides by 3
you get y=6
In conclusion, x=8 and y=6 hence, (8,6)
Answer: No.
Step-by-step explanation: This is not a right triangle because if you add up all the sides, it does not equal 90 degrees.

But if it's 36
<u>IT'S CORRECT</u>
Answer:
= 21.6216% decrease
Step-by-step explanation:
Calculate percentage change
from V1 = 29.6 to V2 = 23.2
(V2−V1)|V1|×100
=(23.2−29.6)|29.6|×100
=−6.429.6×100
=−0.216216×100
=−21.6216%change
=21.6216%decrease
The base representation is 200, because it’s the base number
Hope this helps:)
