Answer:
x = 3.76 ft
Step-by-step explanation:
To find the missing side, "x", solve using proportions.
In similar polygons, the 'new' polygon was created by multiplying every side of the 'old' polygon by the same number. Every side was multiply by the <u>scale factor</u>, "k", which tells you how much a polygon grew (k>1) or shrunk (0<k<1).
Therefore, if you divided the pairs of corresponding sides, they would be equal.
From the diagram, you can tell that the following sides correspond:
CB ~ GF
AB ~ EF
<u>Use the proportion</u>

Substitute values from diagram
Multiply both sides by 6 ft
"x" is isolated. Multiply fraction by combining into numerator
Solved numerator. Divide for decimal answer.

The value of 'x' is 3.76 ft.
30-(11+(18-(48/8×2))+7)+15
= 30-(11+(18-12)+7)+15
= 30-(11+6+7)+15
= 30-24+15
= 21
Recall to always convert the mixed fractions to "improper" fractions first,
Answer:
cost of a box is $3.5
Step-by-step explanation:
given data
sold box = 18
earned = $136.50
solution
we consider here number of boxes of cookies is x
and
for we get Tyler sold cookies box so number of boxes we divide 702 cookies among 18 is
Tyler sold = 
Tyler sold = 39 boxes
and
now we consider here y as cost of each box of cookies,
so for cost or sale price of the cookie boxes here we divided 136.50 dollars among 39 boxes
so
cost of each box = 
cost of each box = 3.5
Thus, the cost of each box was 3.5
