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:

yes, they are parallel because their slopes are the same

Step-by-step explanation:

if you put each equation into slope-intercept form and compare slopes you can see whether they are parallel or not

2x + y = 14

y = -2x + 14

slope = -2

2y + 4x = 14

2y = -4x + 14

slope = -4/2, which simplifies to be -2

Answer:

For every 2 cups of lime juice, the recipe makes 8 cups of limeade; a part and the whole.

Step-by-step explanation:

The ratio shows that for 2 cups of lime juice there needed proportion of 8 cups of limeade.

and, the ratio involve a part and the whole.

A ratio is a comparison between two amounts that is calculated by dividing one amount by the other. The quotient a/b is referred to as the ratio between a and b if a and b are two values of the same kind and with the same units, such that b is not equal to 0. Ratios are represented by the colon symbol (:). As a result, the ratio a/b has no units and is represented by the notation a: b.

Given:

A recipe that makes 8 cups of limeade uses 2 cups of lime juice.

and, ratio = 2:8

Here, the ratio shows that for 2 cups of lime juice there needed proportion of 8 cups of limeade.

and, the ratio involve a part and the whole.

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].

Answer:

Yes Carla is correct.

Step-by-step explanation:

The measurement of the circumference of a circle is 21.3 ft.

The circumference is the perimeter of a circle. That is, the circumference would be the arc length of the circle, as if it were opened up and straightened out to a line segment.

Here, given area of circle = 36 ft²

Area of Circle = πr²

           36 = 3.14 X r²

           r² = 11.46

          r = 3.38 ft.

Circumference of Circle = 2πr

                                       = 2 X 3.14 X 3.38

                                      = 21.25 ft. ≈ 21.3 feet

Thus, the measurement of the circumference of a circle is 21.3 ft.
