Expand and simplify
(2x + 5)2

Answer:

The value of x is 3

Step-by-step explanation:

Here, we want to find the value of x

to do this, we apply the principle of similar triangles

That would work as follows;

4/x + 5 = 7/(2x + x + 5)

4/x + 5 = 7/3x + 5

4(3x + 5) = 7(x + 5)

12x + 20 = 7x + 35

12x - 7x = 35-20

5x = 15

x = 15/5

x = 3

Step-by-step explanation:

23.1+x=-6.2

x=-6.2-23.1

x= -29.3

Answer:

225%

Step-by-step explanation:

Find the difference between the two prices, then divide it by the original price:

78 - 24 = 54

54/24

= 2.25

So, the markup rate is 225%

Answer:

X= -4

Step-by-step explanation:

Answer:

x = -4

Step-by-step explanation:

Distribute the -2 to the parentheses:

-2(-4x - 3) -5x + 3 = -3

8x + 6 - 5x + 3 = -3

Add like terms:

3x + 9 = -3

Solve for x:

3x = -12

x = -4

So, the answer is x = -4

Answer: $13,846.02

Step-by-step explanation:

The car cost $29,750 when it was first bought.

It will then depreciate at a rate of 12% per year. This means that the value of the car reduces by 12% per year.

To find the value of the car in the 6th year, you can use the compound interest formula:

= Value of car * ( 1 - rate) ^ no. of years

= 29,750 * ( 1 - 12%)⁶

= ‭13,816.021581824‬

= $13,846.02

Answer: The answer is s = 14 * 5 = (70) So each swaeter is $3.50

Answer:

s>7

Step-by-step explanation:

she spent more than $42 total so

x>42

we factor in the 14 dollar shirt and 4 sweaters

14+4s>42

isolate x on one side

4s>28

s>7

Answer:

12/15 in simpliest form is 4/5

Step-by-step explanation:

12 / 3 = 4

15 / 3 = 5

Remember that to get or to make a fraction in simpliest forms you need to divide both numerator and denominator by the same number.

12/15 is equal to 4/5.

Hope this helps!!! ;)

Answer:

Percentage change in price = 13.80%

Step-by-step explanation:

Given that:

Original price = £57.99

Decreased price = £49.99

Difference = Original price - Decreased price

Difference = 57.99 - 49.99

Difference = £8.00

Percent change = [tex]\frac{Difference}{Original\ price}100[/tex]

Percent change = [tex]\frac{8.00}{57.99}*100[/tex]

Percent change in price = 13.80%

Hence,

Percentage change = 13.80%

The range of #1 is 13

The range of #2 is 9

The range of #3 is 20

The range of #4 is 59

Step-by-step explanation:

I had a math teacher in 6th grade who taught me a corny, but helpful rhyme.

It is

Hey diddle-diddle

The median's the middle (organize the numbers from least to greatest, then find the number in the middle)

You add (all the numbers), then divide (by how many numbers there are) for the mean

The mode is the one that appears the most (which number do you see more than once?)

The range is the difference between (find the smallest number and the largest number, then subtract the small one from the large one)

See? Corny huh? I hope this helps bro!

The range of data: [tex]52,48,57,47,49,60,59,51[/tex] is [tex]13[/tex]

What is range?

In statistics, the range of a set of data is the difference between the largest and smallest values. Difference here is specific, the range of a set of data is the result of subtracting the sample maximum and minimum.

According to question, we have to find different range.

The range of data: [tex]52,48,57,47,49,60,59,51[/tex]

[tex]=60-47=13[/tex]

The range of data:[tex]5,9,13,6,4,5,8,12,12,6[/tex]

[tex]=13-4=9[/tex]

The range of data: [tex]97,106,99,97,115,95,108,100[/tex]

[tex]=115-95=20[/tex]

The range of data : [tex]27,13,35,19,71,12,66,47,39[/tex]

[tex]=71-12=59[/tex]

Hence, we can conclude that

The range of data: [tex]52,48,57,47,49,60,59,51[/tex] is [tex]13[/tex]

The range of data:[tex]5,9,13,6,4,5,8,12,12,6[/tex] is [tex]9[/tex]

The range of data:[tex]97,106,99,97,115,95,108,100[/tex] is [tex]20[/tex]

The range of data : [tex]27,13,35,19,71,12,66,47,39[/tex] is [tex]59[/tex]

These are interval for increasing (doesnt include relative max-min)

Step-by-step explanation:

Increasing means when we input the value of x and we get the increase of y-value.

A bit hard to imagine? You can look at the graph instead. The name already says it all, Increasing Graph. The graph keeps rising and rising till the max and that is increasing.

The decreasing is when the graph decreases to minimum. The graph would face down for decreasing.

Since we only want the increasing. We look at the graph and tell which region does the graph face up and that is the increasing.
