2 answers:
Answer:
Let X be the number.
Twice the number would be 2x
The difference between the two, would be subtraction, so you would subtract 4 from 2x
The equation becomes 2x-4 = 16
Now solve for x:
2x-4 = 16
Add 4 to each side:
2x = 20
Divide both sides by 2:
x = 20/2
x = 10
The number is 10.
Answer:
2x - 4 = 16
Step-by-step explanation:
We need to express this:
2x - 4 = 16.
To solve for x.
2x = 20
x = 10

Answer:
35.325 in³
Step-by-step explanation:
Since the base of a cylinder is a circle,
area of cylinder= πr²h
Radius, r
= diameter ÷2
= 3 ÷2
= 1.5 inches
Volume of can
= 3.14(1.5)²(5)
= 35.325 in³
The original price would be 190 because if you add 5 to 90 you get 95. 95 is half of the original price so you multiple 95 times 2 to get the original price.
