First you need to set up a formula. Underline all of your givens:
<u>Spent 1/2 on clothes
$6 more for washing windows
Ended with $10.
</u>
now you need to set up an equation.
<u>
</u>You know she ended up with $10. So that will be what it equals. Then you know that she earned $6 in addition to her allowance. So this would be (x= allowance) (x+6)/2 = 10.
<u>
</u>Now you need to solve for x.
Multiply both sides by 2.
<u>
</u>x+6=20<u>
</u>Now subtract both sides by 6 to get x alone:
<u>
</u>x=$14<u>
</u><u>
</u>
Ice is a solid form of water. So then the form of ice would be solid.

Answer:
-18/7
Step-by-step explanation:
When subtracting a negative, the sign becomes positive, so now the equation would be -3 2/7 + 5/7.
By turning -3 2/7 into an improper fraction, you would get -23/7 + 5/7.
-23 +5 = -18 so -18 would be the numerator over the denominator (7) equals -18/7
