Length of BC = 9.88
Answer in detailed step:
Answer:
The length of the first piece is 5 ft
The length of the second piece is 20 ft
The length of the third piece is 25 ft
Step-by-step explanation:
Let
x----> the length of the first piece
y ---> the length of the second piece
z ---> the length of the third piece
we know that
-----> equation A
-----> equation B
----> equation C
substitute equation B and equation C in equation A and solve for x
<em>Find the value of y</em>
<em>Find the value of z</em>
therefore
The length of the first piece is 5 ft
The length of the second piece is 20 ft
The length of the third piece is 25 ft
Answer:
50 cents per lollipop
Step-by-step explanation:
The full bag of lollipops costs 5.99 for 12 lollipops. You must use proportions.
5.99. _ X
———. ——
12. 1
Cross multiply to get 5.99 = 12x. Isolate the variable (x) by dividing by 12. 5.99/12 = 0.499166666666667
Because it is a price, round to the nearest hundredth and it costs about 50 cents per lollipop
