Which is the best value for money?
You must show your working.

Answer:

162$$

Step-by-step explanation:

Answer:

X= 24+7/8 | Y=  24-8x

Steps for answers:

For X:

1. Add y to both sides.

-8x=24+y

2. Divide both sides by -8.

x=-24+y/8

-----------------

For Y:

​1. Add 8x to both sides.

-y=24+8x

2. Multiply both sides by -1.

y=-24-8x

Answer:

50 students

Step-by-step explanation:

24% students in a clan were absent in a day .

Hence, the Percentage of students present is calculated as:.

= 100 % - 24 %

= 76%

From the question, we know that:

If 38 students were present ,what is the total strength in the clan

The total strength of the clan = Total number of students. This is calculated as:

76% × x = 38 students.

76/100 × x = 38

76x /100 = 38

Cross Multiply

76x = 38 × 100

x = 3800/76

x = 50 students

Answer:

x = [tex]11\sqrt{2}[/tex]

y = [tex]11\sqrt{2}[/tex]

Step-by-step explanation:

the ratio of the sides of a 45 - 45 - 90 triangle is shown at the bottom of this answer.

as you can see, it is x:x:[tex]x\sqrt{2}[/tex]

The side given is x[tex]\sqrt{2}[/tex], so you have:

[tex]x\sqrt{2}=22[/tex]

divide both sides by [tex]\sqrt{2}[/tex]

x = [tex]22/\sqrt{2}[/tex]

multiply this by [tex]\sqrt{2} /\sqrt{2}[/tex]

[tex]x = 22\sqrt{2}/2[/tex]

[tex]x=11\sqrt{2}[/tex]

y is also equal so y = [tex]11\sqrt{2}[/tex]

Answer:y=415 x = 21.5

Step-by-step explanation:

We can see 4x-37 = 49

4x = 86

x = 21.5

4(21.5) -3 = 83

Then we can see what the other side is because they are equal

y/5 = 83

83 x 5 = 415

y=415

Answer:

x = 11

Step-by-step explanation:

3 x 11 = 33

33-5 = 28

x = 11

Answer:

10

Step-by-step explanation:

Given

h(x) = 3x - 5

h(x) = 25

3x - 5 = 25

3x = 25 + 5

3x = 30

x = 30 / 3

x = 10

Answer:thanks for 23 points

Step-by-step explanation:

Answer:

8

Step-by-step explanation:

1/10 bottle of paint covers 2/5 of box

2 bottles of paint will cover x of box

Using cross multiplication :

1/10 = 2 / 5

2 = x

(1 / 10)x = 2/5 * 2

x / 10 = 4 / 5

Cross multiply :

5x = 40

Divide both sides by 5

x = 40/5

x = 8

Hence, 2 bottles of paint will be used to paint 8 boxes

Answer:

No.

Step-by-step explanation:

Well, is the points (1, -9) does satisfy the equation y = 3x - 6. Then, substituting the values of x, and, y, into the equation y = 3x - 6,  we should get a true equation.

y = 3x - 6

-9 = 3 * 1 - 6

-9 = 3 - 6

-9 = -3.

So, the points (1, -9) does not satisfy the equation y = 3x - 6.

Answer:

{y|y>1}

Step-by-step explanation:

i hope that this is what you are looking for^_^

This is just a fancy way your teacher saying that when you have an equation y=[tex]4^{x}[/tex]+1, what is y when x=-1,0,3.

We just need to solve by substituting the x in respectively.

x=-1, y=[tex]\frac{5}{4}[/tex]

x=0, y=1

x=3, y=65

Answer:

14/s

Step-by-step explanation:

Bonnie bought 14 sponges. There were s sponges in each package. Choose the expression that shows how many packages Bonnie bought.

Number of sponges = Number of packages

Hence:

s sponges = 1 Package

14 sponges = x

Cross Multiply

s × x = 14 × 1

x = 14/s

Therefore, the expression that shows how many packages Bonnie bought.is given as

14/s

Answer: ≈ 21.46 m²

Step-by-step explanation:

Area of square = 10 x 10 = 100 m²

Area of circle = π(5²) = 25π m²

Area of total = 100 - 25π = 21.46018366

≈ 21.46 m²

Answer:

133.5

Step-by-step explanation:

Answer:

The answer is below

Step-by-step explanation:

In a certain​ year, the amount A of garbage in pounds produced after t days by an average household is given by A = 7.5t.

Plot a graph for t > 0

how many days it will take to get 200 pounds of garbage.

Solution:

a) Let the time in days (t) be on the x axis and the amount of garbage (A) in pounds be on the y axis. Therefore:

At t = 0; A = 7.5(0) = 0

At t = 10; A = 7.5(10) = 75

The graph was plotted using the geogebra online graphing tool.

b) number of days require to get 200 pounds of garbage can be gotten by finding the value t for which A = 200. Therefore:

A = 7.5t

t = A / 7.5 = 200 / 7.5

t = 26.67 days

Step-by-step explanation:

Question is incomplete, we will however explain how the scale works using examples

Answer and explanation:

Given the map scale 1:2000000, the fraction from this 1/2000000 is the representative fraction. The representative fraction is the ratio of distance on the map to the real distance on ground.

With the representative fraction 1/2000000, we can find how many meters on the ground is represented by a unit of measurement in centimeters on the map thus:

Given 1m= 100cm

Representative fraction broken down = 1/2×10000×100

Therefore 1cm on the map = 20000m on ground
