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>
Answer:
Yes they did.
Step-by-step explanation:
So you have the fraction 3/4 and 6/8. If you divide the fraction 6/8 by 2 you will get 3/4 since 6/8 is an unsimplifed form of 3/4.
A rational number is any number that can be written as a/b
Answer:
1/16
Step-by-step explanation:
Given the expression;
To find a constant that will make it a perfect square, we will use the square if the half of coefficient of x
Coefficient of x = 1/2
half of Coefficient of x = 1/2*(1/2)
Half of Coefficient of x = 1/4
square of the half of coefficient of x = (1/4)^2
square if the half of coefficient of x = 1/16
hence the constant that will make it a perfect square is 1/16
13 + 49 = 62
62 - 12 = 50
The answer is 50
