Answer:a=3/4
b=3/4
Step-by-step explanation:
3a+5b=6
9a+7b=12
-3(3a+5b)=-3(6)
9a+7b=12
-9a-15b=-18
9a+7b=12
-8b=-6
b=3/4
3a+5(3/4)=6
3a+15/4=6
3a=9/4
a=3/4
Explanation:
1. you subtract 6x to get 4y alone. which will get you -4y=-6x-16
2. then you divide everything by -4 to get y completely alone.
This will get you the answer of y=6/4y+4
Answer:
Add 9.6 then divide by 3.2
Answer:
the last option
Step-by-step explanation:
I'm smart
Yo sup??
Lenght of two side will be equal to 20 in as its an isoceles triangle.
The third side will be
x^2=b^2+h^2 (by pythagoreas theorem)
=9^2+9^2
x=9√2 in
Therefore the perimeter is = 9+9+9√2
=9√2(√2+1) in
Hope this helps.
