Answer:
x + y = 90
and
x – y = 8
Explanation:
One of two complementary angles = x angle and y angle, x + y = 90
is 8 degrees less than the other = –8 so
x + y = 90
and
x – y = 8
So you could do $1725/3 (divided by) which would give you 575 then mulitply that by two and that will give you the months rent of, $1,150. I hope this helps!
3/9=1/3. To get from 3 to 9, multiply by 3. To maintain the same fraction, also multiply the numerator i.e 1 by 3.
1. -4a-6=-12
add 6 to both sides
-4a-6+6=-12+6
-4a=-6
Divide by -4
2.
add
to both sides but you will need to make a common denominator on the right

Divide
5. -.2p+.4=-1.2
Subtract
-.2p=-1.6
Divide
p=8
6.
Add, made sure you change to common denominator first
Multiply by 4
y=5
Hope that helps
