Answer:
$10
Step-by-step explanation:
x is her weekly allowance.
She spent half her allowance and has ½x remaining.
She earned $7, and now has $12.
12 = ½x+7
x = 10
4/8+16=24? im confused on this statement
<u><em>Step 1: Add Andy's and April's amount of pie together:</em></u>
<u><em /></u>
Andy and April ate 3/10 of the pie and 2/10 of the pie, respectively.
3/10 + 2/10 = 5/10.
So both of them ate 5/10 or 1/2 of the pie.
<u><em /></u>
The unit rate would be found if you made a ratio first of 60:3600. You notice that 60 can go into 3600 by 60 times. This means you get a unit ratio of 1:60. This means that one clownfish cost 60 dollars.
3x-2y=6
1) <span>Add -3x to both sides.
</span><span><span> 3x</span>−<span>2y</span></span>=<span>6
</span>+3x +3x
-----------------
<span>−<span>2y</span></span>=<span><span>−<span>3x</span></span>+<span>6
</span></span><span>
2) Divide both sides by -2.
</span>
![\frac{-2y}{-2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B-2y%7D%7B-2%7D%20)
=
![\frac{−3x+6}{-2}](https://tex.z-dn.net/?f=%20%5Cfrac%7B%E2%88%923x%2B6%7D%7B-2%7D%20)
y=<span><span><span>32</span>x</span>−<span>3
</span></span>
3) Substitute the y with the equation
3x-2(32x-3)=6
3x-64x+6=6
4) Combine like terms
3x-64x+6=6
-61x+6=6
5) Subtract 6 from each side of the equation
-61x+6=6
-6 -6 (+6-5 gets crossed out)
--------------
-61x=0
6) Divide both sides by -61
x=0============================================================
Now that you've got you x intercept, use the x value and substitute it into the
y=32x−3
y=32(0)-3
y=0-3
y=-3(0,-3)
