Answer:

1. x= 9

2. x= −2

3. 51 inches

4. $213.11 each month

Step-by-step explanation:

1. Simplify both sides of the equation.

x + 7 + 7x= 25 + 6x

Combine Like Terms

(x + 7x) + (7)=6x + 25

8x + 7= 6x + 25

8x + 7= 6x + 25

Subtract 6x from both sides.

8x + 7 − 6x= 6x + 25 − 6x

2x + 7= 25

Subtract 7 from both sides.

2x + 7 − 7= 25 − 7

2x= 18

Divide both sides by 2.

2x/2= 18/2

2.  Subtract 5x from both sides.

x − 5x= 5x + 8 − 5x

−4x= 8

Divide both sides by -4.

−4x/−4= 8/−4

3. First find the perimeter of the trapezoid

4 + 3 + 4 + 8= 19

A square has all equal sides

8 * 4= 32

Add them together

19 + 32 = 51 inches

4. Subtract the amount she put for finance from the total

1598.66 - 320 = 1278.66

Then divide that amount by the 6 months

1278.66 divided by 6 = 213.11

$213.11 each month

Leila is at a charity fundraiser and has a chance of receiving a gift 6/17 . The odds in favor of receiving a gift are . Find the probability of Leila receiving a gift.

Answers

Answer:

6 / 23

Step-by-step explanation:

The question is not correct, the correct question is:

Leila is at a charity fundraiser and has a chance of receiving a gift. The odds in favor of receiving a gift are 6:17. Find the probability of Leila receiving a gift.

Solution:

Odds provide a measure of the likelihood of a particular outcome occurring. Odds is the ratio of the number of events that produce that outcome to the number that do not.

The probability of an event occurring is the ratio of number of favorable outcomes to the total number of outcomes possible.

Given that the odds in favor of receiving a gift are 6:17. Therefore:

number of favorable outcome = 6, number of unfavorable outcome = 17

Total number of possible outcomes = 6 + 17 = 23

The probability of Leila receiving a gift = number of favorable outcome / Total number of possible outcomes  = 6 / 23

The probability of Leila receiving a gift = 6 / 23

DOES ANYONE KNOW HOW TO DO THESE???

Answers

Answer:

Step-by-step explanation:

7. The horizontal translation is 3 units to the right, this is determined by the value that is being added or subtracted to x directly. In this case, x is being subtracted by 3 meaning that it is translated 3 units to the right.

8. It is being translated 2 units up. This is determined by the number that is added to the quadratic equation. In this case, it is increased by 2 which means an upward translation. If it was being subtracted it would be a downward translation.

9. Yes, when a quadratic equation has a negative sign outside of it which changes its values it means that it is being reflected.

The length of an equilateral triangle is increased by 5 cm. The perimeter of the new triangle is 72 cm. What is the side length of the original triangle?

Answers

Answer:

19cm

Step-by-step explanation:

An equilateral triangle is a triangle where the length of the 3 sides are the same.

the perimeter is the sum of the 3 sides

for example, if the length of the side of the an equilateral triangle is 5, the perimeter is 5 x 3 = 15

let x = unknown length of side

length after increase = x + 5

(x + 5) x 3 = 72

divide both sides of the equation by 3

x + 5 = 24

subtract 5 from both sides of the equation

x = 24 - 5 = 19cm

What is Population Density?

The population density, or the number of people divided by the area's size, is determined by the number of people who reside there. Numerous creatures' distribution, growth, and migration can all be explained by population density.

Population density = number of people / the area they occupy

Given data ,

A study with a sample that is very different from the population is J. biased.

In statistical terms, bias refers to any systematic error or deviation from the true value that can occur in a study. When a study is biased, the results may not be representative of the population and may not be generalized other settings.

Results from a research may be skewed if the sample chosen is considerably different from the population. Both experimental and observational research may experience this. As a result, alternatives F and G do not offer sufficient details to assess the study's objectivity.

ABCD is a rhombus. The diagonals intersect at point E. If angle CDB= 6x and angle ACD= 2x+10, find x.

Answers

Answer:

x = [tex]10^{o}[/tex]

Step-by-step explanation:

The diagonals of a rhombus are perpendicular to each other, thus the angle at point E is [tex]90^{o}[/tex]. So that ΔCED is a right triangle, and that;

<CDB = <CDE

<ACD = <ECD

<CDE + <ACD + <CED = [tex]180^{o}[/tex] (sum of angles in a triangle)

6x + (2x + 10) + [tex]90^{o}[/tex] = [tex]180^{o}[/tex]

8x + 100 = [tex]180^{o}[/tex]

8x = [tex]180^{o}[/tex] - 100

8x = 80

x = [tex]\frac{80}{8}[/tex]

  = [tex]10^{o}[/tex]

Thus, the value of x is [tex]10^{o}[/tex].
