6 gift boxes are 12.36 inches high
32 gift box are x inches high
This is a proportion question. A proportion is made of 2 equal ratios. If you know 3 parts of the proportion, you can solve for the 4th,
6/32 = 12.36/x Cross multiply
6x = 12.36 * 32 Combine the right.
6x = 395.52 Divide by 6
6x/6 = 395.52/6
x = 65.92
Answer: 65.92
Note
Using a proportion saves you the trouble of finding 1 box and multiplying whatever number you get by 32
-2 = 3x + 7
subtract 7 from both sides
-9 = 3x
divide by 3
-3 = x
check
-2 = 3 (-3) + 7
-2 = -9 + 7
-2 = -2
Answer:
x = 45/7
Step-by-step explanation:
Write as an algebraic equation.
Look at each part in the word question : 0.7 of what number is 4 1/2
"0.7 of what number" can be written as 0.7x
The word "is" means equals.
0.7x = 4 1/2 <= The equation, using 'x' to represent the number.
To find the number, isolate 'x'.
0.7x = 
Convert mixed fraction to improper fraction
0.7x = 
Multiply the whole number by the denominator and add it to the numerator
0.7x = 
Now isolate 'x'
0.7x/0.7 = 
Divide both sides by 0.7
x = Simplify right side
x = 
Rewrite 0.7 as a fraction
x = 
To divide, you multiply a flipped fraction
x = 
Multiply across the top and across the bottom
x = 90/14 Reduce to lowest terms. Top and bottom are divisible by 2
x = 45/7 Answer
