Answer:

144

Step-by-step explanation:

Substitute x with 12 then times 6 by 12 then add 72 to get 144

Answer:

1) x = -11

2) x= -9

3) x = -1

4) x = 32

5) x =  11

Step-by-step explanation:

Answer:

Step-by-step explanation:

11. -1= (5+x)/6 : to get rid of the 6 on the bottom multiply to both sides.

-6=5+x : subtract 5 to both sides

-11 = x

12. 2/3x + 2 = -4 : subtract the 2 to both sides

2/3x = -6 : divide 2/3 to both sides

x= -6/(2/3)

x=-9

13. 7x+2.5=-4.5 : subtract 2.5 to both sides

7x= -7 : divide by 7 to both sides

x= -1

14. 8-3/8x= -4 : subtract 8 to both sides

-3/8x = -12 : divide both sides by -3/8

x=32 : two negatives make a positive

15. -3x - 5 = -38 : add 5 to both sides

-3x=-33 : divide both sides by -3

x= 11 : two negatives make a positive

Answer:

BFA

Step-by-step explanation:

Answer:We can rewrite the expression |14-(6-x)| as follows:

When (6-x) is positive, 14-(6-x) = 14-6+x = x+8

When (6-x) is negative, 14-(6-x) = 14-6+x = x+8

Therefore, we can write the expression without the absolute value symbol as:

x+8

Step-by-step explanation: We have try the two cases when 6-x is negative and when it s positive

Given:

[tex]|14-(6-x)|[/tex]

Answer:

First choice:  A′(−1.5, 2.25), B′(−0.75, 0.75), C′(1.5, −0.75), D′(1.5, 1.5)

Step-by-step explanation:

A(-4, 6)   x 3/8  →  A'(-12/8, 18/8) = A'(-1.5, 2.25)

B(-2, 2)   x 3/8  →  B'(-6/8, 6/8)  =   B'(-0.75, 0.75)

C(4, -2)   x 3/8  →  C'(12/8, -6/8) =  C'(1.5, -0.75)

D(4, 4)    x 3/8  →  D'(12/8, 12/8)  =  D(1.5, 1.5)

Based on the surface area and cost of the boxes, the company saves $11.50 by choosing to make 50 Box 2 instead of 50 Box 1.

To solve this problem, we need to calculate the surface area of each box to determine how much material is needed to make 50 of each box.

The surface area of Box 1 is:

SA1 = 2lw + 2lh + 2wh

SA1 = 2(206) + 2(204) + 2(6*4)

SA1 = 240 + 160 + 48

SA1 = 448 square inches

To convert to square feet, we divide by 144 (since there are 144 square inches in a square foot):

SA1 = 448/144

SA1 = 3.11 square feet

The cost of material for one Box 1 is:

C1 = 1.25 * SA1

C1 = 1.25 * 3.11

C1 = $3.89

The surface area of Box 2 is:

SA2 = 2lw + 2lh + 2wh

SA2 = 2(154) + 2(158) + 2(4*8)

SA2 = 120 + 240 + 64

SA2 = 424 square inches

Converting to square feet:

SA2 = 424/144

SA2 = 2.94 square feet

The cost of material for one Box 2 is:

C2 = 1.25 * SA2

C2 = 1.25 * 2.94

C2 = $3.67

To find the cost savings of making 50 Box 2 instead of 50 Box 1, we calculate the difference in cost:

Savings = (50 * C1) - (50 * C2)

Savings = (50 * 3.89) - (50 * 3.67)

Savings = $11.50

Answer:

the coefficient of 4x is 4

Step-by-step explanation:

The coefficients in the expression 4x + 3y - 16 are:

The coefficient of x is 4

The coefficient of y is 3

The coefficient of the constant term (without a variable) is -16

Therefore, the coefficient of 4x is 4.

Answer:

probably my last question for the day but the answer is 28.26 square centimeters.

Step-by-step explanation:

The formula to find the area of a quarter circle is:

A = (1/4)πr^2

where A is the area and r is the radius.

Substituting the given values:

A = (1/4) × 3.14 × 6^2

A = 28.26

Rounding to the nearest hundredth, the approximate area of the figure is 28.26 square centimeters.

Answer:

[tex]6 {x}^{2} + 4xy[/tex]

Step-by-step explanation:

Expanding brackets means multiplying every term inside the bracket by the term on the outside and then collecting like terms with the aim of removing the set of brackets

[tex]2x(3x + 2y) = 6 {x}^{2} + 4xy[/tex]

.

Step by step:

[tex]2x \times 3x = 6 {x}^{2} [/tex]

[tex]2x \times 2y = 4xy[/tex]

6x² + 4xy

Given equation, 2x(3x+2y)

                            = 2x(3x+2y)

                     Distributive Property

                            = (2x * 3x) + (2x * 2y)

                            = (2 * x * 3 * x) + (2 * x * 2 * y)

                                  Rearranging like terms

                            = {(2 * 3 * x * x) + (2 * 2 * x * y)}

                            = [{(2 * 3) * (x * x)} + {(2 * 2) * (x * y)}]

                            = {(6 * x²) + (4 * xy)}

                            = (6x²) + (4xy)

                            = 6x² + 4xy

Answer:

(4x – 5) – (-3x + 4) can be simplified by distributing the negative sign to the terms inside the parentheses:

(4x - 5) + (3x - 4)

We can then combine like terms by adding the coefficients of x and the constants:

7x - 9

Therefore, the expression that is equivalent to (4x – 5) – (-3x + 4) is 7x - 9.

Answer:

21.35 inches

Step-by-step explanation:

Hello!

The distance around the hat is also called the circumference (the perimeter of a circle). To find this, we use the formula: [tex]C = 2\pi r[/tex], where r is the radius.

If we don't have a given radius when solving for circumference, we can use the diameter, and then the formula would change to [tex]C = \pi D[/tex] (2r is the same as D), where D is the diameter.

Given that the diameter is 6.8, and the desired value of Pi is 3.14, we can solve for the circumference.

The circumference is approximately 21.35 inches.

Answer:

The answer is A

Step-by-step explanation:

y=mx+b is the point slope form and is the form that is used on the equation.

The slope is mx, or in this case 1x. If you're simply looking for a shift in the line, then the slope has to be the same, so we know that b is not the answer. The y-intercept is b, or as the problem's equation shows, 2. The y-intercept is where the line crosses the y-axis (the vertical axis). Since you're looking for a shift downwards, you need the y-intercept to be lower than 2. The only one that matches that is option A.

Step-by-step explanation:

Donation sorting can be considered indirect service because it does not involve direct interaction with the intended beneficiaries of the donations. Instead, it involves organizing, categorizing, and preparing donated items for distribution to those in need. While donation sorting may not involve face-to-face interactions with the people being served, it is still an important aspect of the service process because it helps to ensure that donated items are distributed in an organized and efficient manner, and that they reach the people who need them the most. By volunteering in donation sorting, individuals can indirectly contribute to the betterment of their community and the well-being of those who are less fortunate.

Answer:

B= (27,0)

A= (34,14)

Step-by-step explanation:

The point where the right angle is (34,0). B would be halfway between this and (20,0). It would be 20+34=54 then 54/2. This is 27. (since it lies on y=0, it's just y=0). The point is (27,0).

A is halfway between (34,0) and (34, 28). They have the same X point, so it would be the middle of 28 and 0. 28+0=28, then 28/2= 14. A would be (34,14).

Answer: I believe you just multiply each point by 1/2. So -10/2=-5 and -6/2=-3

So point b will be(-5,-3)
