I ate 6 pieces of my candy. This is 75% of the candy I had. How much candy did I have before
Answer:
The amount of candy you had before is 8.
Step-by-step explanation:
75% + 25% makes 100% percent.
If we take 25% off from 8, you get 6.
A quick way to do this is: 8(.25)
If you solve that, you get 2. 8 - 2 is 6, which is what you originally had.

Dan,Gordon and malachy share some sweets in the ratio 2:2:5. Dan gets 24 sweets.How many did malachy get?
Answer:
60 sweets
Step-by-step explanation:
The total ratio = 2 + 2 +5 = 9
Let x = total sweets shared
Dan got 2/9 of x. This is equal to 24
the equation for this is - [tex]\frac{2}{9}[/tex] × x = 24
to solve for x, divide both sides by [tex]\frac{9}{2}[/tex]
x = 108 = total sweet shared
sweets malachy got = [tex]\frac{5}9}[/tex] x 108 = 60 sweets

If f(x)=2x-4 and x=4
Solve for f(x):
Answer:
dfyrexbjnyyfdc bgg hi ytdxvjud
Answer:
4
Step-by-step explanation:
f(x)=2x-4
f(x)=2(4)-4f(x)=8-4f(x)=4Just plug in 4 into x. If you get confused on what f(x) means, it basically is the output value or the y value. So when plugging in the number for f(x), I recommend not worrying about the symbol f(x) too much.

A rectangle has a perimeter of 23 cm. Its area is 33 cm2. Determine the
dimensions of the rectangle. You must show all work to earn full marks. No work
shown & a correct answer will earn a mark of zero.
Answer:
length = 6 cm; width = 5.5 cm
Step-by-step explanation:
Let the length = x. Let the width = y.
We use the formulas for area and perimeter using x and y, and the given values.
area = length * width
perimeter = 2(length + width)
xy = 33
2(x + y) = 23
Solve the first equation for x:
x = 33/y
Substitute 33/y for x in the second equation.
2(33/y + y) = 23
66/y + 2y = 23
Mulrtiply both sides by y.
66 + 2y^2 = 23y
2y^2 - 23y + 66 = 0
(2y - 11)(y - 6) = 0
2y - 11 = 0 or y - 6 = 0
y = 11/2 = 5.5 or y = 6
xy = 33
x * 11/2 = 33
x = 33 * 2/11
x = 6
Answer: length = 6 cm; width = 5.5 cm
