Use the model to solve for x.
A) no solution
B) x = 3
C) x = -3
please help me.

a) The step where Mardie first made an error is given as follows: Step 1, as the negative sign means that the sign of each term inside the parenthesis should be changed.

b) The correct expression is given as follows: -8.6b + 28.

The expression in the context of this problem is defined as follows:

(-3.78b + 12) - (4.82b - 16).

The negative sign before the parenthesis means that the sign of each term inside the parenthesis is changed, hence:

-3.78b + 12 - 4.82b + 16.

This is the step where Maddie made the first error.

Then, to simplify the expression, we combine the like terms, as follows:

b(-3.78 - 4.82) + 12 + 16 = -8.6b + 28.

Answer: 20 ft=w

Step-by-step explanation: Perimeter = width + width + length + length

100 = w+w+w+10+w+10

100=4w+20  subtract 20 from both sides

80=4w  Divide both sides by 4

20 ft=w

Step-by-step explanation:

You choose the longest side which is 12 and apply the theory of phitagors

The longest side which is the hypotenuse in a right triangle = square root the square sum for each side

So to be a right triangle it should be

\( \sqrt{ {9}^{2} + {6}^{2} } = 10.8 \: \: that \: doesnt \: equal \: 12\)

So it's not a right triangle.

Look at the famous right triangle whose side are 5(hypotenuse), 4, 3

\( \sqrt{ {4}^{2} + {3}^{2} } = 5\)

So it's a right triangle

Answer: 0.557 in

Step-by-step explanation:

       We will use the formula for the circumference of a circle, substitute known values, and solve for r (radius). 3 1/2 = 3.5.

Given:

  C = 2πr

Substitute known values:

  (3.5) = 2πr

Divide both sides of the equation by 2π:

  (3.5) = 2πr

  r = 0.557 in

Answer:

D) This is a reflection because triangle ABC has been flipped over the x-axis.

Step-by-step explanation:

You can see that A'B'C' is congruent to ABC

You can also confirm the fact that it is a reflection by counting the distance from a point to the X axis and comparing it to the corresponding point- for example, A is 2 units above the X axis, and A' is 2 units below.

Answer: 1. |-6| + |3| = 9 Units

Step-by-step explanation: To figure out the distance between two points on a coordinate plane, we first need to think about the quadrants. If they are both in the same quadrant, we SUBTRACT. If not, we add. Since point A is in Quadrant II and point B in Quadrant I, we have to add.

(-6, 4)

(3, 4)

So, the answer to this question would be, |-6| + |3| = 9 Units.

Answer:  -7

Step-by-step explanation: To find the mean, here is the equation =

Divide the sum of all values in a data set ÷ the number of values = mean (average)

Step 1 :

So we do =

17 + -25 + 3 + -29 + -15 + 7 = -42

So the sum of the integers is -42

Step 2 :

We divide the sum by the number of values.

17, -25, 3, -29, -15, 7

1      2   3     4      5   6

So there are 6 values.

We do =

-42 ÷ 6 = -7

So the mean (average) of these integers is -7

If you climb up 5 flights of stairs will give zero. The correct option is D.

Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that situations can be represented with an integer​ that, when combined with the opposite of −5​, makes​ 0.

If you climb up 5 flights of stairs it will give the positive value of 5 when it is added to -5 then it will give zero.

Therefore, If you climb up 5 flights of stairs will give zero. The correct option is D.

192 hours per day / 8 hours per person per day = 24 people

Step-by-step explanation:

Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:

720 person-days x 8 hours = 5,760 hours

To complete the project in 30 days, the total number of hours needed per day is:

5,760 hours / 30 days = 192 hours per day

Answer:

Step-by-step explanation:

area of a square = side^2

area of a cube = 6 x side^2

let the side be a .

6a^2 = 600

=> a^2 = 600/6

=> a^2 = 100

Hence the area of one of its faces is 100 square inches.

or in plain terms without using those formulas,

6 faces of the cube have 600 square inches

=> 1 face of the cube has 600/6 = 100 square inches

Step-by-step explanation:

The value of A/B is given as follows:

A/B = -2.

From the graph, the function has a vertical asymptote at x = 1, hence the value of B is given as follows:

B = -1 -> as x + B = 0 -> x = -B = -1.

When x = 0, y = -2, hence the value of A is obtained as follows:

A/-1 = -2

A = 2.

Then the division is given as follows:

A/B = 2/-1 = -2.
