Let's say cookies are 2x. If there are 2x cookies then there are 7x cupcakes. Now, 2x cookies + 7x cupcakes = 36 desserts.

9x = 36

So, x = 4

Now, remember that cookies = 2x. 2x = 2 times 4 = 8.

She will bake 8 cookies.

Three solutions for 5x+7y=19
ddd [48]
Just sub in ANY number for x and solve for y

5x + 7y = 19.....lets say x = 0
5(0) + 7y = 19
7y = 19
y = 19/7...so when x = 0, y = 19/7.....(0,19/7)

5x + 7y = 19....lets say x = 1
5(1) + 7y = 19
5 + 7y = 19
7y = 19 - 5
7y = 14
y = 14/7
y = 2.....so when x = 1, y = 2......(1,2)

5x + 7y = 19.....lets say x = 3
5(3) + 7y = 19
15 + 7y = 19
7y = 19 - 15
7y = 4
y = 4/7...so when x = 3, y = 4/7.....(3,4/7)

2.33 kg = 2330 gr

Grams of grapes that are left after giving 800 grams to her brother:

2330 - 800 = 1530 gr

Grams of grapes each sister will get if Doreen shares the remaining equally:

sasho [114]
To find the volume of this storage bin, you will use the formula for volume of a cylinder and of a cone.

V = Bh (cylinder)
Pi x r^2 x h
Pi x 2^2 x 10

V = 1/3 x pi x r^2 x h
1/3 x pi x 2^2 x 3
