Answer:

4

Step-by-step explanation:

f(x)=2x-4

Just 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.

Answer:

? = 4.29

Step-by-step explanation:

Remark

Let  x be the question mark. You get the proportionality by using the dimensions of the little triangle to the dimensions of the large triangle.

Equation

14/(14+ 4) = 15/(x + 15)                   Combine like terms on the left

14/18 = 15/(x + 15)                          Cross multiply

14*(x + 15) = 18 * 15                        Simplify the right

14(x + 15) = 270                             Divide by 14

x + 15 = 270 / 14

x + 15 = 19.29                               Subtract 15 from both sides

x = 19.29 - 15

x = 4.29    

Answer:

$300.64

Step-by-step explanation:

Step one:

Given data

Jennifer had $256.86

She made a deposit of $43.78

Required

The total amount in the account

Step two:

To get the balance, we need to sum the previous amount with the deposited amount

Total= 256.86 +43.78

Total=$300.64

The balance is $300.64

Answer:

one solution

Step-by-step explanation:

both equations equal out to y=-4x+6

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

Answer:

Step-by-step explanation:

5x - 12y = 24

-12y = -5x + 24

12y = 5x - 24

y = 5/12x - 2

slope is 5/12

Answer:

50.24 yards=Circumference

Step-by-step explanation:

So first the formula to find circumfence is π*diameter

The diamtere is 16

π is told to be counted as 3.14

3.14*16=50.24

So the Circumfrnce is 50.24

Answer: The correct answer is B.

Step-by-step explanation:

We are given the cost of restaurant meal of M. Clark is $25.50.

and she has given 20% of the meal's cost as a tip to the waiter.

Step 1: Calculating the amount of tip paid

Total tip paid = $5.1

Step 2: To find the total amount, we add the cost of the meal and the tip paid

Total amount = Cost of the meal + Tip paid

Total amount = $25.50 + $5.10

Total amount paid by Ms. Clark = $30.6

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.

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
