First you will need to cross multiply.

5/x = 2/8
~ Do 5 times 8. =40
~ Then do 2 times x. =2x.

2x=40
/2   /2
~~Now divide each side by 2 and you should get x=20.

X=20
Hope this helps!!! :D

The dimensions of a 7-cm by 2-cm rectangle are<br> multiplied by 3. How is the area affected?
Soloha48 [4]

Answer:

Original rectangle:  Since the area of a rectangle is the length * width, the area of this rectangle is 7 * 2 = 14 square cm.

New rectangle: The new dimensions of this are 7*3 = 21 cm by 2*3 = 6 cm.  To find the area, we multiply these two together.  21*6 = 126 square cm.

126 is 9 times greater than 14, so the area will be multiplied by 9.

andre [41]

Answer:

5/18

Step-by-step explanation:

Then John keeps his and there are  8 pieces of fruit in the bowl,  

3 tangerines and 5 clementines.

P (Clementine) = number of clementines/ total = 5/8

P (tangerine, no replacement, Clementine) = P (tangerine) * P (Clementine)

                                                                        = 4/9 * 5/8 =5/18
