Answer:
Let's solve for x.
x+y+z=8
Step 1: Add -y to both sides.
x+y+z+−y=8+−y
x+z=−y+8
Step 2: Add -z to both sides.
x+z+−z=−y+8+−z
x=−y−z+8
Answer:
x=−y−z+8
Answer:
Width = 3/4 units or 0.75 units
perimeter of the rectangle = 23/2 = 11 1/2 units or 11.5 units
Step-by-step explanation:
A rectangle has two opposite sides equal in length. The 2 opposite sides are also parallel to each other.
The area of a rectangle = LW
where
L = length
W = width
The area of the rectangle = 3 3/4 units² = 15/4 units²
Length = 5 units
Therefore,
15/4 = 5W
multiply both sides by 4
15 = 20W
divide both sides by 20
W = 15/20
W = 3/4
Width = 3/4
Perimeter of the rectangle = 2L + 2W
Perimeter of the rectangle = 2(L + W)
Perimeter of the rectangle = 2(5 + 3/4)
perimeter of the rectangle = 2(23/4)
perimeter of the rectangle = 23/2 = 11 1/2 units or 11.5 units
Answer:
Step-by-step explanation:
Step-by-step explanation:
1. divide 78% by 100 = 0.78
2. multiply 0.78 and 3.822
3. solve and get 2.98116
4. if you want you could round
5. x = 2.98166 or 3
The answer would be 2.83 because you'd round the .82 up to .83 because of the 8 in the thousandths place.
