Answer:

x = 6

Step-by-step explanation:

7 + 5x = 2x + 25

first subtract 7 from both sides to isolate 5x on the left

5x = 2x + 18

then subtract 2x from both sides to isolate all of the x terms to one side

3x = 18

then divide 18 by 3 to solve for x

x = 6

Answer:

Expressions C and D correctly determine the markup price.

Step-by-step explanation:

A markup in mathematics is when an object's price is raised by a certain percentage. Therefore, because we are told that the telescope is originally $400 and is marked up by 32%, we can actually mathematically evaluate this.

When you markup a price, you multiply the original price by [tex]1+x[/tex], where x is the percentage at which the object is marked up. However, x needs to be in decimal form for it to work out.

[tex]\frac{32}{100} = \small\boxed{0.32}[/tex]

Therefore, with this new decimal, we can add 1 to it.

[tex]1 + 0.32=\small\boxed{1.32}[/tex]

Finally, we multiply this result by the original price.

[tex]1.32 \times 400=\small\boxed{528}[/tex]

Therefore, we can already confirm that Expression C is one way to find the markup price.

Now, we can test the math for expressions D and E to see if either of these will equal $528.

Expression D is basically saying to add 32% of 400 to the original price. This would work out because we marked up the original price by 32%. Therefore, we can confirm that Expression D is also an expression that can be used to determine the markup price.

[tex]400 + 400(0.32)\\400(0.32) = 128\\400 + 128 = \small\boxed{528}[/tex]

Finally, we also need to check expression E. This expression is saying to add the already marked up price to 400. This would not be correct.

[tex]400 \times 400(1.32)\\400(1.32) = 528\\400 \times 528 = \small\boxed{\$ 211,200}[/tex]

Therefore, it has been determined that Expression C & Expression D are both equations that will find a markup price.

Answer:

y= 8x +9

Step-by-step explanation:

Slope-intercept form:

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is 8, m= 8.

Substitute m= 8 into the equation:

y= 8x +c

Given that the y-intercept is 9, c= 9.

Substitute c= 9 into the equation:

y= 8x +9

Thus, the equation of the line is y= 8x +9.

Answer:

"I Only" is the correct answer

Step-by-step explanation:

Given inequality is:

-10>3x-6

In order to check which numbers are solution to the given inequality, we will put each number one by one in the inequality. If the inequality is true after putting the number, the number is the solution of the inequality.

So,

I . -10

Putting -10 in the inequality

[tex]-10>3x-6\\-10>3(-10)-6\\-10>-30-6\\-10> -36[/tex]

The inequality results in true after putting x=-10 so -10 is the solution of inequality.

II. 5

Putting 5 in the inequality

[tex]-10>3x-6\\-10>3(5)-6\\-10>15-6\\-10>9[/tex]

The equality doesn't hold true for x=5 so 5 is not the solution of the problem.

III. -1

Putting -1 in the equation

[tex]-10>3x-6\\-10>3(-1)-6\\-10>-3-6\\-10>-9[/tex]

Inequality doesn't hold true for x=-1 so it is not the solution of the inequality.

Hence,

"I Only" is the correct answer as only -10 is the solution of inequality.

At sit and Stay School, 12 lessons cost $96. The unit rate for each lesson will be:

= $96/12 = $8

At Canine Community Center, 25 lessons cost $125. The unit rate will be:

= $125/25 = $5

The better deal is at Canine Community as it's cheaper.

The unit rate for lessons at Sit and Stay School is $8 per lesson

The unit rate for lessons at Canine Community Center is $5 per lesson

The lower unit rate is $5 which is that of Canine Community.

The lessons at Canine Community are the better deal.

Tim can buy 4 caps and will left with Rs.20 to spare

The unitary method is a method in which you find the value of a unit and then the value of a required number of units.

Given here tim can buy 3 hats from Rs.120 thus each hat cost Rs.40

Thus price of 4 hats is Rs.160 and he will be left with Rs.20 to spare.

Hence, Tim can buy 4 caps and will left with Rs.20 to spare

Answer:

-2.1

Step-by-step explanation:

The y-intercept will be (0, 12.6) if Damien graphed the following linear function on an (x, y) coordinate plane f(x) = 6x + 12.6.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

The linear function is:

f(x) = 6x + 12.6

To find the y-intercept plug x = 0

f(0) = 0 + 12.6

f(0) = 12.6

Thus, the y-intercept will be (0, 12.6) if Damien graphed the following linear function on an (x, y) coordinate plane f(x) = 6x + 12.6.

Answer:

Step-by-step explanation:

Setting up your problem and solving:

In the question it says the ratio is students to professors right? So 18 to 1.

Write that down: Students to Professors is 18 to 1.

We know that there are 702 students in that college correct?

Write that down: 702 students in the college

We are trying to find how many professors there are so...let's do that.

Number 1:

Set your equation: have your fraction bar and equal sign like this: --- = ---

On the top, we have 1 so... 1/? = ?/?

On the other top we have the x...: 1/? = x/?

Why? Because we do not know the total of professors there are so that is X.

We put the number 1 on the other side because we know that there is only 1 out of 18 professors to students.

Number 2:

On the bottom, we will have 18...: 1/18 = x/?

On the other bottom we have 702...: 1/18 = x/702

Why? Because we know that there is a total number of 18 to 1 students on the ratio and a real total of 702 students.

Number 3.

Now you have your equation set up: 1/18 = x/702

The next step is yours: cross multiple, divide on the bottom or top or find the comparison.

I'm going to divide by the bottom okay? so.. 18/702

Set that up.

(702/18)

702/18 is 39!

SO in the end there is a total of 39 professors!

'x=39'

Answer:

we get [tex]\mathbf{gf(2)=-\frac{1}{3}}[/tex]

Step-by-step explanation:

We are given:

[tex]f(x)=1-2x\\g(x)= \frac{1}{x}\\h(x)=x^3+1[/tex]

We need to find value of [tex]gf(2)[/tex]

[tex]gf(2)=g(f(2))[/tex]

First putting f(x) inside of g(x) and then putting x=2

[tex]gf(x)=g(f(x))\\gf(x)=\frac{1}{1-2x}[/tex]

Now putting x=2 to find [tex]gf(2)[/tex]

[tex]gf(x)=\frac{1}{1-2x}\\gf(2)=\frac{1}{1-2(2)}\\gf(2)=\frac{1}{1-4}\\gf(2)=\frac{1}{-3}\\gf(2)=-\frac{1}{3}[/tex]

So, we get [tex]\mathbf{gf(2)=-\frac{1}{3}}[/tex]
