2x -3y = 13
4x -y = -9
Multiply the second equation by -3 to make the coefficient of Y opposite the first equation.
4x -y = -9 x -3 = -12x + 3y = 27
Now add this to the first equation:
2x -12x = -10x
-3y +3y = 0
13 +27 = 40
Now you have :
-10x = 40
Divide each side by -10:
x = 40 / -10
x = -4
Now you have a value for x, replace that into the first equation and solve for y:
2(-4) - 3y = 13
-8 - 3y = 13
Add 8 to both sides:
-3y = 21
Divide both sides by -3:
y = 21/-3
y = -7
Now you have X = -4 and y = -7
(-4,-7)
Answer:
10 boys
Step-by-step explanation:
6:2 simplfies to 3:1 30 / 3 = 10
30:10 simplfies down to 6:2
the idea being, you multiply the "x" by some power of 10 that moves the repeating part to the left of the decimal point and the split it like above.
Hello!
The Correct Answer's would be:
2. Federal tax rate is 15%
<span>net weekly pay = 13644.80/52 * ( 1 - .15) - 53.60 = $169.44
3. </span>28% * 134350
<span>.28 * 134350
</span>37,618 divide by 52 = 723.42<span>
And
4. Her refund would most likely be "</span>19566.58".
Hope this Helps! Have A Wonderful Day! :)
