You can solve percentage problems by converting percent into decimals and multiplying.
60% equates to .6, so
235 x .6 = 141
You put 141 dollars in your savings account.
B(a+b)-a(a-b)
ab+b^2-a(a-b)
ab+b^2-a^2+ab
b^2-a^2+2ab
Rearrange into standard form
Final answer: -a^2+2ab+b^2
Its D, bc everything is even on both sides.
Answer:
$30.53
Step-by-step explanation:

Answer:
No solutions .........
Step-by-step explanation:
3x-4y=7
-12x+16y=10
Multiply 1st equation by 4, you get:
12x-16y=28
Add the 1st and 3rd equations:
0x+0y=38
0(x+y)=38
(x+y)=38/0 which is undefined
