Heterogeneous and homogeneous
Xy= 540
y= 5x/3
x(5x/3)=540
5x^2/3=540
1630=5x^2
x=sqrt(1620/5) = sqrt(324)= 18
x= 18yd
y=30yd
answer: 18 x 30 yards
Answer:
I think its c. 40
Step-by-step explanation:
Eliminate the fractions by multiplying by least common multiple.
4,9,12 all go into 36 evenly. Multiply entire equation by 36.
36/4 = 9
36/9 = 4
36/12 = 3
New equation looks like:
Answer:
A
Step-by-step explanation:
The measurements of the segments fall on similar triangles. This means the lengths of each segment can be found using proportions.
Remember, a proportion is an equation which sets equal ratios equal to each other.

To solve for c, multiply numerators and denominators across the equal sign:
24c = 32(15)
24c = 480
c = 20
