3x - 15 = 39
+ 15 +15
3x = 54 (divide by 3 on each side)
X = 18

C is the true statement :)
To find each box, you have to multiply the number above the box and the number to the left of the box.
For the bottom left, we have 4 x 0.8 or 3.2.
For the bottom right, we have 0.8 x 0.6 or 0.48.
Answer:
3 1/3 feets
Step-by-step explanation:
Given that:
Height of aquarium = 1 3/4 feets
Area of aquarium = 5 5/6 ft²
The length of aquarium = x
Aquarium is shaped in the form of a rectangle :
Area of a rectangle = Length * width
5 5/6 = x * 1 3/4
35/6 = 7x/4
Cross multiply :
7x * 6 = 35 * 4
42x = 140
x = 140 / 42
x = 3 14/42
x = 3 1/3 feets
Hence, Length of the back of aquarium is 3 1/3 feets
