Jean is making bar graphs for a representation. She is planning for the length and width of the bars to have a ratio of 3:2, so
that they satisfy this equation.
2l = 3w
If one of the bars is 7 centimeters wide, what should be it's length. Find and explain how you found the solution to this answer.
A.21 cm
B. 14 cm
C. 10 1/2 cm
D. 4 2/3 cm
Please explain how you found the answer.
1 answer:
Answer: C. 
Step-by-step explanation:
Given: The ratio of length to width = 3:2,such that the equation she formed is
2l=3w
The width of bar w= 7 cm
Then substitute this value in the equation and solve , we get

Hence the length of the bar =

$530.40/4= $132.60
$132.60 x 3=$397.80
Or
$530.40 x .75= $397.80
Would it be 9 because 8 times 3 equals 24 and 3 times 3 equals 9
3*3+4*4=x*x and 9+16=25 so x is 5 and then add other sides so 5+8+4+5
