Answer:
61 Inches
Step-by-step explanation:
<em>A foot is 12 inches. </em>
1. Multiply 12 by 5.
2. Add the extra inch.
<em>The stack of books is 61 inches high.</em>
The answer would be 7/24.
1. Let
x = first piece
y = second piece
z = third piece
2. Arrange it into an equation
x + y + z = 50
3. The second piece is 4 times as long as the first piece so 4x = y.
The third piece is 5 times as long as the first piece so 5x = z
4. Now substitute the values
x + (4x) + (5x) = 50
5. Simplifying makes the equation into 10x = 50
6. Do the opposite of multiplying to get rid of the 10 which is dividing. Divide 50 by 10.
x = 50/10
x = 5
7. Now substitute x in 4x and 5x
4 * 5 = 20
5 * 5 = 25
8.
x = 5
y = 20
z = 25
700,000
Look at the ten thousands place. There is a 7, which is greater than five, so that means you have to round the number 6 up to a seven
