I know this is like the 700th question I've asked​
AysviL [449]

Answer:

BC = 15

Step-by-step explanation:

Because of parallel lines, AD and BE, triangles ADC and BEC are similar.

In similar triangles, the lengths of corresponding sides are proportional.

AC/BC = DC/EC

We see that AC = AB + BC = 3 + BC

Also, DC = DE + EC = 2 + 10 = 12

(3 + BC)/BC = 12/10

(3 + BC)/BC = 6/5

Cross multiply.

5(3 + BC) = 6BC

15 + 5BC = 6BC

15 = BC

BC = 15

Tom had 7/12 of a pizza. His little sister came along and took 2/5 of his pizza away. How much pizza does Tom have left?
Delvig [45]
To find the answer,we can first calculate how much her sister took away by multiplying the original amount he has to the amount her sister took.

Her sister has:
7/12×2/5
=7/30

We can then find the amount of pizza left by deducting the pizza he has to the answer we found above:

7/12-7/30
=35/60- 14/60
=21/60
=7/20

Therefore he has 7/20 of a pizza left.

An alternative way to find the answer:
7/12×(1-2/5)
=7/12×3/5
=7/20

Hope it helps!
