Answer:4

Step-by-step explanation:

The equation of the two-step problem is 2x = x + 19

The conditions are given as

Let the variable in the equation be x

So, a possible equation is as follows

2x = x + 19

The solution to the equation is as follows

2x = x + 19

Subtract x from both sides

x = 19

Hence, the equation of the two-step problem is 2x = x + 19

A) The reason why Chris had higher savings by retirement age, is because he saved $5000 annually from ages 25 to 65 while susan did so only from ages 25 to 35 .

B) The reason why Susan had a higher retirement savings than bill is because Susan started investing 10 years earlier than bill and so her investment had a longer period to compound.

A) From the given exponential graph, we see that Chris curve was simialr to that of susan between ages 25 to 35 and suddenly Chris curve began to rise at a faster rate than that of Susan after that until when retired at 65 years of age.

Since we are told that chris continued that amount till retirement at 65, we are told that susan contributed the same amount for only that period between ages 25 and 35. Thus, it means that the reason why Chris had higher savings by retirement age, is because he saved $5000 annually from ages 25 to 65 while susan did so only from ages 25 to 35 .

Answer:

  [tex]\textsf{C}\quad f^{-1}(x)=24-6x[/tex]

Step-by-step explanation:

You want the inverse function of f(x) = 24 -x/6.

The function relates x to y by y = f(x). The inverse function gives the reverse relation: x = f(y). Solving this for y gives the inverse function in the form you want.

  x = f(y)

  x = 4 -y/6 . . . . . use definition of f(x)

  6x = 24 -y . . . . multiply by 6

  y = 24 -6x . . . . add y-6x

The solution of the system of linear equations is (x, y, z) = (1, 1, - 3).

In this problem we find a system of three linear equations with three variables, which can be resolved by several methods. In this case, we shall use the method of substitution. First, clear the variable x in the third equation:

x = 4 - 3 · y

Second, substitute x in the first two equations:

3 · (4 - 3 · y) + 2 · y - z = 8

12 - 9 · y + 2 · y - z = 8

- 7 · y - z = - 4

2 · (4 - 3 · y) + 2 · z = - 4

8 - 6 · y + 2 · z = - 4

- 6 · y + 2 · z = - 12

Third, clear z in the first equation derived in the previous step:

z = 4 - 7 · y

Fourth, substitute z in the second equation derived in the second step:

- 6 · y + 2 · (4 - 7 · y) = - 12

- 6 · y + 8 - 14 · y = - 12

- 20 · y = - 20

y = 1

Fifth, calculate y and x:

z = 4 - 7 · 1

z = - 3

x = 4 - 3 · 1

x = 1

The solution of the system of linear equations is (x, y, z) = (1, 1, - 3).

The number of coffee product he sells is 38.

He makes $11.50 per hour.

He earns $0.50 for each of these items he sells.

Last week he worked 30 hours and earned $364.

Therefore, the number of coffee product he sells last week can be calculated as follows:

let

x = number of coffee product he sells.

364 = 11.50(30) + 0.50(x)

364 = 345 + 0.50x

364 - 345 = 0.50x

19 = 0.5x

divide both sides by 0.5

x = 19 / 0.5

x = 38

Therefore, the number of coffee product he sells is 38.

They sold 10 bags of butter popcorn, 20 bags of kettle corn and 26 bags of cheddar cheese.

Here, we are given that two boy scouts were selling popcorn for a fundraiser.

Their total revenue = $640

Let the bags of butter popcorn be x

then, the bags of kettle corn sold = 2x

and the bags of cheddar popcorn sold = 2x + 6

Cost of kettle corn = $15/ bag

Cost of butter popcorn = $8/ bag

Cost of cheddar popcorn = $10/ bag

Thus, the total revenue from from kettle corn = $30x

total revenue from from butter popcorn = $8x

total revenue from from cheddar popcorn = $10(2x + 6)x

Thus, we will get the following equation-

30x + 8x + 10(2x + 6) = 640

38x + 20x + 60 = 640

58x + 60 = 640

58x = 580

x = 580/ 58

x = 10

Thus, 2x = 20 and 2x + 6 = 26

Hence, they sold 10 bags of butter popcorn, 20 bags of kettle corn and 26 bags of cheddar cheese.

The value of x is 11 units and the length of side RS = 11x-4 is 117 units.

with measurement BC = 60, CD = 50.

Triangle RST : RS = 11x-4, ST = 70

Two figures are said to be similar if they are the same shape. In more mathematical language, two figures are similar if their corresponding angles are congruent , and the ratios of the lengths of their corresponding sides are equal.

Given:

BC = 60 and CD = 50

RS = 11x - 4 and ST = 70

Now, considering

BC : CD = RS : ST

60 : 50 = 11x - 4 : 70

60/50 = (11x - 4)/70

50 * (11x - 4) = 70 * 60

11x - 4 = 84

11x = 88

x = 11

So, RS = 11x - 4

RS = 11 x 11 - 4

RS = 117

Hence, the value of x is 11 and the length of side RS is 117

Answer:

B: 3x+(4x+2)=180

Step-by-step explanation:

Supplementary angles are those angles that sum up to 180 degrees. The question gives you the two angles that compose the 180 degree angle thus you get the equation:

Angle 1 + Angle 2 = Supplementary Angle

In this case we see that these two angles are Angles B and C and a supplementary angle is 180 degrees thus:

(4x+2)+3x = 180

Furthermore this also allows you to find x.

The required measure of the angle m∠B is 121°.

Given that,
Angle A and B are two vertical equal angles.
m∠B = 3x - 17
m∠A = 2x + 29

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
m∠A = m∠B
2x + 29 = 3x - 17
-x = - 46
x = 46

Now,
m∠B = 3  *46 - 17
m∠B =  138 - 17
m∠B = 121°

Thus, the required measure of the angle m∠B is 121°.

slope = 2/3

(-1 - y)/(-6) = 2/3

By adding the number of cups needed for each cake, we conclude that you will need 25 cups of ingredients to make the 4 cakes.

We know that the recipe calls for:

That is for a single cake, so in a single cake you need a total of cups given by the sum of the above quantities, this gives:

(1 + 3/4) + (4 + 1/5) + 3/10 = (1 + 4) + (3/4 + 1/5 + 3/10)

= 5 + (3/4 + 2/10 + 3/10) = 5 + (3/4 + 5/10) = 5 + (3/4 + 1/2) = 5 + 5/4

= 5 + 4/4 + 1/4 = 6 + 1/4

Each cake needs (6 + 1/4) cups of ingredients, so 4 cakes will need:
