Multiply 3x +y =23 by -4
x+4y=4
-12x+(-4y)=-92
Add together
-11x = -88
x = 8
Plug x in to find y.
8 + 4y = 4
Subtract 8 from each sides
4y = -4
Divide by 4
y = -1
So the answer is x =8, y= -1
I hope that helps!
Answer:
I'm going to help you through this...
Step-by-step explanation:
1. Draw your line through the middle of the equal sign
2. How do you get x by itself? You divide the -5 by -5 because those two cross out.
Area = (base times height) / 2
Can rewrite it as
A= b * h * 1/2
16 = (x^(1/3)) * ( x^(1/2)) * (1/2))
Multiply by 2 to simplify
32 = x^(1/3) * x^(1/2)
32=x ^(5/6)
X=64
Base = 4
Height = 8
Please look below at how you multiply variables that have fractions as exponents (you need to add the exponents, common denominator and all that)
The answer is 1,200 but all you have to do is figure out what 4% of 5000 is and then multiply that by 6
Well...
0.08
X 10
