Mary spent half of her allowance going to the movies . She washed the family car and earned seven dollars . What is her weekly a
Debora [2.8K]
If Mary spent half of her allowance the equation will begin with 1/2x or 0.5x where x is her allowance and 0.5 is half of her allowance spent. Mary also earned 7 dollars by washing the car so this will be added to her allowance spent.
The problem says that after Mary has spent half of her allowance at the movies she was left with 18 dollars so that means that the equation must be equal to 18.

The equation you want to set up is

0.5x+7=18
Where, 18-7=11
0.5x=11
11/.5 = x
x = $22

Thus, Mary has a weekly allowance of 22 dollars.

Write the equation of the circle centered at (4, - 9) with diameter 16.<br> HELP A GIRL OUT
iragen [17]

Answer:

16= (x-4)^2 +(y+9)^2

Step-by-step explanation:

hey! The formula for the equation of a circle is r^2= (x-h)^2 + (y-k)^2

r= the radius (in your case you have the diameter so you do not need to square it)

(h,k)= is the center coordinates, so your center coordinate would be (4, -9). You now have your h (h=4) and your k (k=-9) so you can plug it in the formula! :)

a nice rating would help out
