Answer:

[tex]Total = \$5d - 2[/tex]

Step-by-step explanation:

Represent Alice with A, her friend with F and you with Y.

From the question, we have:

[tex]A = \$d[/tex]

[tex]F = 2 * A[/tex] --- Twice as much Alice means 2 times Alice's earnings

[tex]Y = F - 2[/tex] --- 2 less than her friend

Required

Determine the total amount

[tex]A = \$d[/tex]

Substitute [tex]\$d[/tex] for A in [tex]F = 2 * A[/tex]

[tex]F = 2 * \$d[/tex]

[tex]F = \$2d[/tex]

Substitute [tex]\$2d[/tex] for F in [tex]Y = F - 2[/tex]

[tex]Y = \$2d - 2[/tex]

The total amount is calculated by adding the earnings of Alice, her friend and you

[tex]Total = A + F + Y[/tex]

[tex]Total = \$d + \$2d + \$2d - 2[/tex]

[tex]Total = \$5d - 2[/tex]

Hence, the total earnings is 5d - 2

Answer:

  21

Step-by-step explanation:

When secants meet, the product of the length of the pieces from the meeting point to the two circle intersection points is the same for all.

  KL·KM = KJ·KC

Assuming the marks inside the circle apply only to the lengths inside the circle:

  8(8+x+5) = 7(7+2x+1)

  104 +8x = 56 +14x

  48 = 6x

  8 = x

Then the measure of MK is ...

  MK = x+13 = 8+13

  MK = 21

Answer:

202.3 ounces of real silver

Step-by-step explanation:

Another example would be like pizza. If there are 6 slices of pizza in each box, then 2 boxes of pizza would have 6 + 6 slices = 12 slices. It is 6 slices each * 2 boxes = 12 slices total. The same applies to the coin situation, for every additional coin, multiply 0.85 by the number of coins to get the total weight of real silver.

If there are 238 silver coins, then you have 238 0.85 ounces of real silver. Multiplying 238 by 0.85 to simplify gives you 202.3 ounces of real silver.

Answer:

208?

Step-by-step explanation:

im not sure if this is 100% correct but, all I did was:

238/0.85

Answer:

[tex]y= -\frac{2}{3}x + 12[/tex] --- (1)

[tex]y = -2x -6[/tex] --- (2)

Step-by-step explanation:

Solving (a): Line Equation

[tex](x_1,y_1) = (3,10)[/tex]

[tex](x_2,y_2) = (6,8)[/tex]

First, calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{8 - 10}{6 -3}[/tex]

[tex]m = \frac{-2}{3}[/tex]

[tex]m = -\frac{2}{3}[/tex]

The line equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex] --- slope intercept formula

This gives:

[tex]y - 10 = -\frac{2}{3}(x - 3)[/tex]

[tex]y - 10 = -\frac{2}{3}x + 2[/tex]

Solve for y

[tex]y= -\frac{2}{3}x + 2+10[/tex]

[tex]y= -\frac{2}{3}x + 12[/tex]

Solving (b): Line Equation

[tex](x_1,y_1) = (2,-10)[/tex]

[tex](x_2,y_2) = (-4,2)[/tex]

Calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

[tex]m = \frac{2 -(- 10)}{-4 -2}[/tex]

[tex]m = \frac{2 + 10}{-6}[/tex]

[tex]m = \frac{12}{-6}[/tex]

[tex]m=-2[/tex]

The line equation is then calculated using:

[tex]y - y_1 = m(x - x_1)[/tex]

This gives:

[tex]y - (-10) = -2(x - 2)[/tex]

[tex]y +10 = -2(x - 2)[/tex]

[tex]y +10 = -2x +4[/tex]

Solve for y

[tex]y = -2x +4-10[/tex]

[tex]y = -2x -6[/tex]

Answer:

Answer:

[tex]1.\ y = 2x - 1[/tex]

[tex]2.\ y = -4x + 5[/tex]

Step-by-step explanation:

Solving (1): The line equation in y intercept form;

Given

[tex]m = 2[/tex]

[tex](x_1,y_1) = (4,7)[/tex]

This is calculated using the following formula

[tex]y - y_1 = m(x - x_1)[/tex]

Substitute values for m, x1 and y1

[tex]y - 7 = 2(x - 4)[/tex]

Open Bracket

[tex]y - 7 = 2x - 8[/tex]

Make y the subject

[tex]y = 2x - 8 + 7[/tex]

[tex]y = 2x - 1[/tex]

Solving (2): The line equation in y intercept form;

Given

[tex]m = -4[/tex]

[tex](x_1,y_1) = (-1,9)[/tex]

This is calculated using the following formula

[tex]y - y_1 = m(x - x_1)[/tex]

Substitute values for m, x1 and y1

[tex]y - 9 = -4(x - (-1))[/tex]

[tex]y - 9 = -4(x + 1)[/tex]

Open Bracket

[tex]y - 9 = -4x - 4[/tex]

Make y the subject

[tex]y = -4x - 4 + 9[/tex]

[tex]y = -4x + 5[/tex]

Answer:

-21

Step-by-step explanation:

18-3z = 2z - 6z -3

18-3z = -4z -3

-3z+4z= -3-18

z=-21

Answer:

If you mean "z" instead of "x", the answer should be -21.

Step-by-step explanation:

18 - 3z = 2z - 6z - 3

-3z - 2z + 6z = -18 - 3

z = -21

Answer:

x=4 or x=−8

Step-by-step explanation:

Let's solve your equation step-by-step.

(x+2)2=36

Step 1: Simplify both sides of the equation.

x2+4x+4=36

Step 2: Subtract 36 from both sides.

x2+4x+4−36=36−36

x2+4x−32=0

Step 3: Factor left side of equation.

(x−4)(x+8)=0

Step 4: Set factors equal to 0.

x−4=0 or x+8=0

x=4 or x=−8

Answer:

first option

Step-by-step explanation:

The perimeter is the distance around the composite shape, which is composed of a rectangle and a semi- circle.

P = 12 + 16 + 12 + πr ← ( rectangle and semi- circle )

   = 40 + (3.14 × 8)

    = 40 + 25.12

    = 65.12 in

----------------------------------

A = (16 × 12) + (0.5πr² ) ← rectangle and semi- circle

   = 192 + 0.5 × 3.14 × 64)

    = 192 + 100.48

    = 292.48 in²

Answer:

10 cm³

Step-by-step explanation:

The equation for density is: d = m/v, where d is the density, m is the mass, and v is the volume.

Here, d = 2.5 and m = 25.0, so plug these into the equation to solve for v:

d = m/v

2.5 = 25/v

Multiply both sides by v:

2.5v = 25

Divide by 2.5:

v = 25/2.5 = 10

Thus, the volume is 10 cm³.

Answer:

D

Step-by-step explanation:

The y-intercept is -1 in the equation, it is not shown in the graph. The graph shows it as 1. The slope is incorrect as well in the graph, for every x, y increases by 3, but in the equation for every x, y should increase by 1/3. Both are wrong.

Hope this helps!

Answer:

8 1/8 or 8.125

Step-by-step explanation:

8 goes into 64 8 times. There is a remainder of 1 left over. When you divide 1 by 8, you get .125. That is added to 8.

The solution of expression after divide is,

⇒ 8.125

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that'

The expression is,

⇒ 65 divided by 8

Now, We can divide as;

⇒ 65 divided by 8

⇒ 65 ÷ 8

⇒ 8.125

Thus, The solution of expression after divide is,

⇒ 8.125

x² + 9= 0

(move internode)

x²= -9 (heve no solution and parentheses )

if the number is negative and we are asked to find the root of n (if n is an even number). then it has no solution. example that have solution:

x²= 9

x = √9

x= 3

because, (3)²= (3) × (3)

= 9

or it could be: (-3)²

The annual income is 140,000 dollars

Step-by-step explanation:

If you add the percentage of Entertainment and Savings, you will get a total of 21%. 21% is equal to 0.21. If you divide 29,400 (the Corresponding value to the fraction) by 0.21 (the Corresponding fraction to its value). You will get 140,000 dollars. By dividing 29,400 by 0.21, it means that you will get the value of 1 whole of the amount of annual income.

Answer:

x > -2

Step-by-step explanation:

First, you simplify both sides of the inequality by combining like terms

[tex]-8x + 2x -16 < -5x + 7x[/tex]

[tex]-6x - 16 < 2x[/tex]

Then, you add 6x to both sides in order to isolate x (bring all the Xs to one side)

[tex]-6x - 16 + 6x < 2x + 6x[/tex]

[tex]-16 < 8x[/tex]

Lastly, you divide by 8 in order to cancel out 8x solve for x. Since 8 is not a negative number, you DO NOT flip the sign.

[tex]\frac{-16}{8} < \frac{8x}{8}[/tex]

[tex]-2 < x[/tex]
