The 2 triangles in the big triangle are similar so we can write
3x / 3x - 2 = 5x / 3x 

9x^2 =  15x^2 - 10x
6x^2 - 10x = 0
x(6x - 10) = 0
x= 0 or  5/3

Kieva made 5 times as many cookies as she did cupcakes. If she made 48 deserts in all , how many cupcakes did she make ?
VikaD [51]

Kieva made 8 cupcakes. 8 * 5 + 8 = 48 desserts.

In order to get this, you just have to try out different numbers of cupcakes and adjust based on whether it's too many desserts total, or not enough.

Another way to figure it out is to say that 1 cupcake + 5 cookies = 6 desserts. Then just divide 48 by 6 to get 8 which will then show you that Kieva made 8 cupcakes.

1. To solve this exercise you must apply the formula for calculate the perimeter of a circle, which is shown below:

P=2r\pi

Where r is the radius of the circle.

2. You can calculate the radius of the circle by dividing the diameter by 2, as following:

r=\frac{30ft}{2}\\r=15ft

3. Substitute this value into the formula. Then, you obtain that the result is:

P=(2)(15ft)(\pi)\\P=94.24ft

Two angles are supplementary. One angle can be represented by 2x, while the other by 3x-10. What is the value of 2x? Based on th
liubo4ka [24]
Supplementary angles = 180
2x +3x-10 = 180
5x -10 =180
5x -10 +10 =180+10
5x =190
5x/5 =190/5
x = 38
2x=76
3x-10= 3(38)-10=104

The measure of angles are 76 and 104
