If $g(x) = 3x + 7$ and $f(x) = 5x - 9$, what is the value of $f(g(8))$?

Step-by-step explanation:

There are x kids in the group

So, adults are 13-x people

(13-x)(12) + x(8) = 124

156 - 12x + 8x = 124

156 - 124 = 4x

4x = 32

x = 8

There are 8 kids in that group.

Answer:

120 cm^2

Step-by-step explanation:

The area of a rectangle is it's length(l)  times its width(w):  

Area = l*w

Area = (12 cm)*(10 nm) = 120 cm^2

Question :-

Answer :-

[tex] \rule {180pt} {2pt} [/tex]

Given :-

To Find :-

Solution :-

As per the provided information in the given question, we have been given that the Lenght of Rectangle is 12 cm . Breadth of Rectangle is given 10 cm . And, we have been asked to calculate the Area of Rectangle .

For calculating the Area , we will use the Formula :-

Therefore , by Substituting the given values in the above Formula :-

⇒ Area of Rectangle = Lenght × Breadth

⇒ Area of Rectangle = 12 × 10

⇒ Area of Rectangle = 120

Hence :-

[tex] \underline {\rule {180pt} {4pt}} [/tex]

Answer:

You can also divide the standard hourly rate by 2 and then add this amount to their standard rate. For example, if the hourly rate is $10, then divide $10 by 2 to produce $5. When you add that $5 to the $10 rate, this overtime rate equals $15. As another example, if someone makes $20 per hour, then the overtime rate is $30 ($20 x 1.5 = $30).

B. The experimental probability must equal the theoretical probability.

Step-by-step explanation:

6x + 9(-5x-3) = 6x + 9*(-5x) + 9*(-3) = 6x -45x - 27 = -39x - 27

Hope that helps!

I think the question should be as follow:

➙ 6x + 9 - ( 5x - 3 )

➙ 6x + 9 - 5 x + 3

➙ 6x - 5x + 9 + 3

➙ x + 12

➙ x = -12

Anyways I've also solved according to the provided question:

‎ㅤ‎ㅤ‎ㅤ➙ 6x + 9 (-5x - 3 )

‎ㅤ‎ㅤ‎ㅤ➙ 6x - 45x - 27

‎ㅤ‎ㅤ‎ㅤ➙ - 39 x - 27

Further, we can solve for x ;

‎ㅤ‎ㅤ‎ㅤ➙ - 39 x - 27 = 0

‎ㅤ‎ㅤ‎ㅤ➙ - 39 x = 0 + 27

‎ㅤ‎ㅤ‎ㅤ➙ x = - 27 / 39

Considering a proportional relationship for the situation, the correct conclusion is given as follows:

(17,3) is viable.

A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:

[tex]y = kx[/tex]

In which k is the constant of proportionality.

In this problem, since there is a proportional relationship, it has to have point (0,0), hence the viable points are (-2,7), (17,3) and (20,5), and the correct conclusion is:

(17,3) is viable.

Answer:

Marcy is correct

Step-by-step explanation:

If you had 3 straws that were the SAME length then there would only be 1 possible way to arrange them because no matter what order you put them in to form a triangle the outcome would always be the same because all 3 straws are the same length.

Since there are different lengths of straws, there are 3 possible ways you can arrange them so basically, there are multiple ways you can arrange the straws to make a triangle.

Marcy is correct.

Answer:

Step-by-step explanation:

➊ To find the smallest number, let us consider the three consecutive numbers be x, x + 1, and x + 2.

Given :

According to the question,

↦ x + x + 1 + x + 2 = 18

↦ 3x + 3 = 18

↦ 3x = 18 - 3

↦ 3x = 15

↦ x = 15/3

➦ x = 5

∴ Hence, the required value of x is 5.

➋ Now we have the value of x. So, by putting the value of x in the assumed numbers we will find out the numbers and then check which is the smallest number.

➲ First number = x = 5.

➲ Second number = x + 1 = 5 + 1 = 6.

➲ Third number = x + 2 = 5 + 2 = 7.

∴ Hence, the smallest number is 5.

✻ Verification ✻

↦ x + x + 1 + x + 2 = 18

Putting x = 5 we get,

↦ 5 + 5 + 1 + 5 + 2 = 18

↦ 5 + 6 + 7 = 18

↦ 18 = 18

➦ LHS = RHS

∴ Hence, Verified ✔

Answer: (2, -1)

Step-by-step explanation:

Answer:

x = 5

Step-by-step explanation:

Two secants have equal ratios when (in this case) they are split up as

AB * AC = AD*AE

Givens

AB = x-2

AC = (x - 2 + x+ 4) = 2x + 2

AD = 4

AE = 5 + 4 = 9

Substitute and solution

(x - 2) (2x + 2) = 4 (9)                  Expand the left, Combine the right

2(x^2 - x - 2) = 36                       Divide both sides by 2

x^2 - x - 2 = 18                            Subtract 18 from both sides

x^2 - x - 2 - 18 = 18 - 18              Combine

x^2 - x - 20 = 0                           This factors

(x - 5)(x + 4) = 0                           Only one of these factors works

x - 5 = 0                                       Add 5 to both sides.

x = 5

Answer: Will need 7 week of time to afford a car worth 1932

Step-by-step explanation:

Missing information : car is worth 1932

Will works 7 hours day, 6 days a week.

=> Number of hours worked in a week = 7 * 6 = 42 hrs

paid 9.20 an hour

=> will  Weekly payment = 42 *9.2  =  386.4

will : mum = 5:2.

=> Will share = (5/7) * 386.4 =  276

car is worth  1932

Number of Weeks taken by will  to afford  a car  = 1932/276 = 7

divide 40 into ratio of 5:2

The ratio of monthly income to the saving of a family is 5:2.
