We will check if y and 60cm are parallel.
If the lengths 28cm, 56cm and 15cm, 30cm are in proportion, then y and the segment 60cm are parallel.

OK. We know: y and 60cm are parallel. Therefore we have equation:

<h3>Answer: y = 90 cm.</h3>
to find a percent you have to find a equivalent fraction that equals to ___\100
Answer:
+ 3x +9x +27 = 0
x(x+3)+9(x+3)=0
(x+3)(x+9)=0
x=-3, x=-9
Step-by-step explanation:
a=1 b=12 c=27
sum=12
factor=27x 1
3x9
also 3+9=12
Answer:
the total amount spent is $31.68
Step-by-step explanation:
The computation of total amount spent as follows:
= 1.4 pounds × $9.15 + 0.8 pounds × $10.75 + 2.6 pounds × $3.95
