Answer:
6 cm,12 cm,8 cm
Step-by-step explanation:
add the perimeter of the first triangle to get 65
then divide 65 by 26 to get 2.5
then divide all the side lengths by 2.5
15/2.5=6
20/2.5=8
30/2.5=12
So, what is the total lenght of the pieces that wer cut off?
we multiply the lenght by the number:
4

*5=20+

=21

and we subtract this from the original pipe, that is
30

-21

we need to bring the two fractions to the same denominator (by multiplying the fraction art in the first by 3 and 4 the second):
30

-21

=9

so the correct answer is D!
For the second one 1 mph equals 1.6 km so i’m pretty sure it would be all of them
198 + (199*3) + (200*2) +(201*5) + (202*2) = 2604
frequency = 1 + 3 +2 + 5 + 2 = 13
201 = (2604 + x )/14
multiply both sides by 14
x = 201*14 = 2604 +x
x = 2814 = 2604 +x
subtract 2604 from both sides:
x = 2814 - 2604
x = 210 cm
height of new player = 210 cm
-50 because if he owes 10 different people the same amount it would be -50 because he owes them money
