Answer:
32 squared ft
Step-by-step explanation:
Answer:
Step-by-step explanation:
We can solve for this equation by isolating 
on one side. To do this, we can "reverse" the equation.
Let's divide both sides by 3.
Add 3 to both sides:
Multiply both sides by two (since 
)

Answer:
Height of the building that cast a shadow of 45 meters is 27 meters
Step-by-step explanation:
This is a direct variation and let height of the object represent H and shadow represent S
Hence H∝S
H = KS, where K=constant of proportionality
K = H/S
K = 6/10 = 0.6
Hence height of a building that cast a shadow of 45 meters
H = KS
H = 0.6 × 45 = 27 meters
Answer:
Within 52 weeks, the amount of water in the two fish tanks will be the same.
Step-by-step explanation:
First, let's make the two equations equal to each other by placing an equal sign.
832 - 5x = 1040 - 9x
Now, that they are equal to each other, we can solve for x.
Okay, so we can move -5x to the other side by adding both sides with 5x.
832 = 1040 - 4x
Then, subtract 1040 from both sides to move it to the other side.
832 - 1040 = -208
-208 = -4x
Lastly, divide both sides by -4 to get the value of x.
-208/-4 = 52
x = 52
