Step-by-step explanation:

Page 5. 5, 6, 7, 8

Page 6. 12.5

Page 7. 4(3x)

Page 8. 0, 4

i don't know number 7

Answer:

9, 10

12.5

4 + 3x

0, 4

Step-by-step explanation:

5. This just looks to be some simple multiplication so lets work this out 1 by 1 .

Plugging each answer possible into m this is what we get :

8 x 5 = 40

8 x 6 = 48

8 x 7 = 56

8 x 8 = 64

8 x 9 = 72

8 x 10 = 80

Considering these answers lets find which ones are GREATER than 67.

That would be :

72, 80

So your answers would be :

9, 10

6. Alright so this one is asking you what the value of q would be in the equation :

0.5q = 6.25

So to find q we need to see that whatever q is will be multiplied by 0.5. And this answer will be equal to 6.25 due to the = sign. So an easy way of doing this is actually just finding what 6.25 x 2 is. Since q x 0.5 will equal to 6.25, finding 6.25 x 2 is just flipping the equation in a way.

So doing this we get 12.5 which is the very top answer of that question.

8. Alright so it looks like this question is just meant to make your brain turn into a raisin when you read it, but it isn't that hard.

Lets lay everything out :

Joe is 4 more than triple the age of luke.

x represents lukes age (x = Lukes age)

And we are finding the expression that shows joes age.

Alright so looking at the problem lets look at the key word MORE. More means addition in the math world usually so lets go off that. Lucky for you that's all you need cause you only have one addition answer here but lets still go over it why don't we.

4 + 3x

4 represents the "4 MORE than lukes age"

Then we have 3. The 3 represents the "triple the age of luke"

And finally x represents Lukes age.

So if we do 3 multiplied by x (Lukes age) we get triple lukes age :

4 + (Triple lukes age)

So now we just add the 4 and it would be in theory :

Triple Lukes age + 4 = Joes age. And that's all they want.

And then finally we have 7.

This is one fairly simple just another one meant to confused you a bit it seems.

You're basically taking the variable which is q and adding +2 to it and checking to see if the sum of that is less than 7.

So lets do that with the answers given

We will just input the number where q is in the equation and then check! :

2 + 0 < 7

2 plus 0 is 2, and is less than 7!

2 + 4 < 7

2 plus 4 is 6, and is less than 7!

2 + 5 < 7

2 plus 5 is 7. It would be correct if there was an equal sign or less than or equal to sign. But there is not so this is incorrect.

2 + 7 < 7

2 plus 7 is 9, which is greater than 7.

2 + 9 < 7

2 plus 9 is 11, which is greater than 7.

So lets look at what we plugged in that is less than (<) 7 and those are our answers! :

0 , 4

The others are either equal or greater than 7 which is not what we are looking for. So the only two correct answers here are 0, 4.

I hope this helps you! If you have any questions feel free to ask them in the comments and I will help you the best I can! :)

Answer:

S(n) = 12,000(–0.05)n

Step-by-step explanation:

The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]

Original population , P  =  12000

Rate of decline, r = 5%

r  =  5/100

r  = 0.05

The number of years = n

The population of students after n years will be given by the formula:

[tex]S =P(1-r)^n[/tex]

Substitute r = 0.05 and P = 12000 into the formula above

[tex]S=12000(1-0.05)^n\\\\S=12000(0.95)^n[/tex]

The function that represents the number of students, S, in the school district after n years is [tex]S=12000(0.95)^n[/tex]

Answer:

The system of linear equations that could be used to find the length and width of the rectangle will be:

l = 2w + 3 cm  

2w + 2l = 66

Hence, option D is correct.

Step-by-step explanation:

Let the width of the rectangle be = w cm

Given that the length, l, of a rectangle is 3 cm longer than twice the width, w.

Thus, the length of the rectangle be:

l = 2w + 3 cm  

We know that the perimeter of the rectangle is:

P = 2w + 2l

Given that the perimeter of the rectangle = P = 66 cm

so substitute P = 66 in P = 2w + 2l

P = 2w + 2l

66 = 2w + 2l

Therefore, the system of linear equations that could be used to find the length and width of the rectangle will be:

l = 2w + 3 cm  

2w + 2l = 66

Hence, option D is correct.

Answer: $22.68

Step-by-step explanation:

17.50 times 0.08 = 1.40

17.50 + 1.40 = 18.90

Now the tip:

18.90 times .2 = 3.78

The first important details are given at the start, where the beginning amount of snow is 12 inches. This is a positive number.

Then, the next sentences tell us that the snow melts at a pace of 2 inches for an x number of days.

This can be represented by -2x because the word "melts" indicates a negative value.

From this, the equation can be made :)

Hai!

Your answer should be A.

Answer: 250

Step-by-step explanation:

20% of 15,000 is 3,000

3,000/12=250

Answer:

$3000 Per Month

Step-by-step explanation:

Hi there,

How I like to solve these is first take the total number (15,000) and divide it by 100 to then find how much 1% of 15,000 is.

So :

15,000 / 100

=

150

Now we know :

1% = $150

We need to find 20% now so all we do is multiply.

150 x 20

($150 x 20%)

= $3,000 Per Month

I hope this helps!

Given:

The function is

[tex]y=\tan x[/tex]

To find:

The domain of the given function.

Solution:

We know that, domain is the set of x-values or input values.

We have,

[tex]y=\tan x[/tex]

[tex]y=\dfrac{\sin x}{\cos x}[/tex]

The functions sin x and cos x are defined for all real values of x. So, the function tan x is defined for all real values of x except those value for which cos x = 0.

So, domain is [tex]-\infty<x<\infty, x\neq \dfrac{\pi}{2}+n\pi[/tex].
