360-90-90-52=128
Ans is 17 . Solved it Down below. Hope it help
One easy way is first solve for y
3x-5y=9
minus 3x both sides
-5y=-3x+9
divide both sides by -5
y=
so
if x=-1
y=
y=
y=
if x=0
y=
y=
y=
if x=1
y=
y=
y=
9.) <span>1/2(4x-6)=11
</span>Multiply 4 and -6 by 1/2
2x-3=11
Add 3 to both sides
2x=14
Divide 14 by 2
Final Answer: x=7
10.) 2/3(6x-9)=-34
Multiply 6 and -9 by 2/3
4x-6=-34
Add 6 to both sides
4x=-34
Divide -34 by 4
Final Answer: x=-8.5
Do you mean find AB? There's no info on D so we can't find AD.
However, AB is 18.
Subtract BC from AC (18 from 36) to get the remaining AB (18).
