Answer:

x = -1.6

Step-by-step explanation:

Solve for x:  

Combine like terms.  Here we combine 1.6x and 3.4x, obtaining 1.8x on the right side of the equation and -2.88 on the left side:

-2.88 = 1.8x

Solve for x by dividing both sides by 1.8:

x = -2.88/1.8, or x = -1.6

Minus 3.75 from 50 to find the removed amount.

Answer:

Cost of the gift = $53.75

Step-by-step explanation:

Total cost of the gift = cost of the earrings + (cost of the earrings × sale tax)

Cost of the gift = $50 + ($50 × .075)                      7.5% = .075

Cost of the gift = $50 + $3.75

Cost of the gift = $53.75

Answer: Multiply 4.50 x 10= 45.00$

Step-by-step explanation:

Answer:

$7.50

Step-by-step explanation:

Divide the cost by 6 to find the price of one 1lb:

4.50 ÷ 6 = 0.75

Now multiply this by 10 to find the cost of 10lbs:

0.75 x 10 = 7.5

∴ The cost is $7.50.

Answer:

It's 14

Step-by-step explanation:

k(-1)=6(-1)+8=-6+8=2

h(k(-1))=>h(2)=4+5(2)=4+10=14

Answer:

14

Step-by-step explanation:

Evaluate k(- 1) then substitute the value obtained into h(x)

k(- 1) = 6(- 1) + 8 = - 6 + 8 = 2 , then

h(2) = 2² + 5(2) = 4 + 10 = 14

Answer:

-19 and 3

Step-by-step explanation:

-19 x 3 = -57

-19 + 3 = -16

Answer:

Step-by-step explanation: To find the answer to "What two numbers have a product of 57 and a sum of 16?" we first state what we know. We are looking for x and y and we know that x • y = 57 and x + y = 16.

Before we keep going, it is important to know that x • y is the same as y • x and x + y is the same as y + x. The two variables are interchangeable. Which This means that when we create one equation to solve the problem, we will have two answers.

To solve the problem, we take x + y = 16 and solve it for y to get y = 16 - x. Then, we replace y in x • y = 57 with 16 - x to get this:

x • (16 - x) = 57

Like we said above, the x and y are interchangeable, therefore the x in the equation above could also be y. The bottom line is that when we solved the equation we got two answers which are the two numbers that have a product of 57 and a sum of 16. The numbers are:

5.35425

10.64575

That's it! The two numbers that have a product of 57 and a sum of 16 are 5.35425 and 10.64575 as proven below:

5.35425 • 10.64575 = 57

5.35425 + 10.64575 = 16

Given the replacement set for an equation is {10, 24, 25, 36}, the solution set of the equation is 36

Let the unknown number required in the replacement set be "x"

If "5/6 of the number is 30, this is expressed mathematically as:

5/6 of x  = 30

5x/6 = 30

5x = 6 * 30

5x = 180

x = 180/5

x = 36

This shows that the solution set of the equation is 36

Answer:

58 sq. units

Step-by-step explanation:

1. split them into 3 shapes

of course it is possible to count them all out, but the more efficient way would be to find the area of each shape and the add them all up.

2. find the area of rectangle a

so you can split one into a recantagle that separates itself from the 2 squares at the bottom

area formula: L x W

so the length of that rectangle is going to be 5, once you count the scares of that side. the width would be 10 when you count the top side of how wide it is.

5 × 10 = 50

3. find the area of the 2 squares

you don't need to find both, because one you find one, you find the other. so the length for the square would be 2 while the width is 2 as well.

2 × 2 = 4

so the area is 4, for each square.

50 + 4 + 4 = 58

Answer:

Sarah gets 2 A's.

Step-by-step explanation:

Sarah's mother gives her $10 for each B she receives. She received 3 B's, so 3x10 is 30. You subtract 80-30. You get 50. She receives $25 for each A. You then divide 50 by 25, and are left with 2. The answer is that Sarah received 2 A's on her report card.

Answer:

16ft^2

Step-by-step explanation:

2 times 6 is 12

2 times 2 is 4

Add 12 and 4

Which is 16ft^2

Hope this helps!

Answer:

16ft

Step-by-step explanation:

Easy way to do this is to split it into 2 different figures then add the area of them both together. In this case, I split the figure into a rectangle and a square.

6 x 2 = 12ft for the rectangle.

2 x 2 = 4ft for the square

Then add them together to get 16ft.

Step-by-step explanation:

A spinner in an algebra problem is generally considered to have equal probabilities for equal areas. It is also generally considered to have the characteristic that the value produced by the next spin is independent of the value produced by the last spin.

With those assumptions in mind, the probability of getting a 3 is always 0.25. It is never anything else with this 4-section spinner.

Graf 2 is correct

Step-by-step explanation:

The correct graph that represents the linear relationship is Graph B with a positive slope.

The table shows a linear relationship between the number of months enrolled and the total cost paid for the membership.

To determine which graph represents this relationship, we need to check if the cost increases or decreases as the number of months enrolled increases. If the cost increases, it means the graph should have a positive slope. If the cost decreases, it means the graph should have a negative slope.

Let's look at the table:

Number of Months Enrolled                                   Total Cost

1                                                                               75

2                                                                               100

3                                                                                 125

As the number of months enrolled increases, the total cost increases. Therefore, the graph should have a positive slope. From the given options, the graph that correctly represents this linear relationship is Graph B, which has a positive slope.

Answer:

the answer would be f(x)=-5x+41

Step-by-step explanation:

you start by calculating the change in y (or f(x)) and dividing that by the change in x or y2-y1/x2-x1. the answer you should get is the slope (mx). from there you calculate the y intercept (b) by simply finding when x=0. now you put it all together, y=mx+b or f(x)=-5x+41

Answer:

[tex]x = -\frac{19}{3}, y = 4[/tex] or [tex](-\frac{19}{3}, 4)[/tex]

Step-by-step explanation:

Given the systems of linear equations, 3x + 6y = 5 and -3x - 3y = 7:

Equation 1: 3x + 6y = 5

Equation 2: -3x - 3y = 7

The best method to use for the given system is the process of elimination, since the coefficients of x in both equations have opposite signs.

3x + 6y = 5

-3x - 3y = 7

       3y = 12

[tex]\frac{3y}{3} = \frac{12}{3}[/tex]

y = 4

3x + 6y = 5

3x + 6(4) = 5

3x + 24 = 5

3x + 24 - 24 = 5 - 24

3x = -19

[tex]\frac{3x}{3} = \frac{-19}{3}[/tex]

[tex]x = -\frac{19}{3}[/tex]

Verify whether the values for x and y satisfy both equations: [tex]x = -\frac{19}{3}, y = 4[/tex]

Equation 1:  3x + 6y = 5

[tex]3(-\frac{19}{3}) + 6(4) = 5[/tex]

-19 + 24 = 5

5 = 5 (True statement).

Equation 2:  -3x - 3y = 7

[tex]-3(-\frac{19}{3}) - 3(4) = 7[/tex]

19 - 12 = 7

7 = 7 (True statement).

Therefore, the solutions to the given systems of linear equations are: [tex]x = -\frac{19}{3}, y = 4[/tex], or [tex](-\frac{19}{3}, 4)[/tex].

x = -19/3, y = 4
