You can just multiply the top and the bottom by the same number, and you will get equivalent fractions.
Answer:
Step-by-step explanation:
Three times a number x : 3x
Three times a number x increase by 4: 3x +4
Five times the number x: 5x
5x = 3x +4
Subtract 3x from both the sides.
5x - 3x = 3x +4 - 3x
2x = 4
Divide both sides by 2
2x/2 = 4/2
x=2
The number is 2
<em>What you need to find is the extra amount of plywood. To do that, you must find the area of the square and the area of the circle and subtract them to find the answer.</em>
Formulas:
area of a square: A = bh
area of a circle: A =
square measurements:
b = 28
h = 28
circle measurements:
(≈3.14)
r = 14
A = (28)(28)
A = 784
area of square = 784 in^2
A = 3.14 (
)
A = 3.14 (196)
A = 615.44 in^2
784 - 615.44 = 168.56
The amount of plywood left over is 168.56 in^2.
Answer:
1126.4
Step-by-step explanation:
5.97 x 1024 =6113.28
4.87 x 1024= 4986.88
6113.28-4986.88 =1126.4
