Answer the following algebraic equation:

3x-5+9(72/8)+4=2(4x-6)

Point Value- 20 points

Answers

Answer 1

Answer:

X=18.4

Step-by-step explanation:

3x-5+9(72/8)+4=2(4x-6)

3x-5+9(9)+4=2(4x-6)

3x-5+81+4=8x-12

3x-5+85=8x-12

3x+80=8x-12

3x-8x=-12-80

-5x=-92

x=-92/-5

x=18.4

Checking our work:

3(18.4)-5+9(72/8)+4=2(4(18.4)-6)

55.2-5+9(9)+4=2(73.6-6)

55.2-5+81+4=2(67.6)

50.2+85=135.2

135.2=135.2

Answers

Answer:

C and D are parallel

Step-by-step explanation:

If b⊥c and b⊥d, then that means that they are both parallel because they both have a 90 degree anglewith line B.

Answer:

| | (Parallel)

Step-by-step explanation:

I'm assuming that is what it is asking. if b and c are perpendicular, that means they form 90 degrees on all angles. The same for b and d. So if both c and d are perpendicular to b, then they are parallel.

Two men are decorating a room. One has painted 20 m² and the
other only 6 m². They continue painting and manage to paint
another x m'each. If the first man has painted exactly three times
the area painted by the second man, find the value of x.

Answers

Answer:

1 m²

Step-by-step explanation:

The first man painted:

x + 20

The second man painted:

x + 6

If the first man painted 3 times more, then:

x + 20 = 3(x + 6)x + 20 = 3x + 183x - x = 20 - 182x = 2x = 1

Answers

Answer:

No Solution

Step-by-step explanation:

2x + y = 1

y = 1 - 2x

4x + 2(1 - 2x) = -2

4x +2 - 4x = -2

2 = -2

The statement is false, therefore there is no solution.

Step-by-step explanation:

There are 84% out of 225. First find 10%. To do that divide the number by 10, so 225 ÷ 10 = 22.5 Next, do 22.5 x 8. Then you have 80%. Now, all that is need ed is the 4%. To get that, divide 225 by 100. Multiply the answer by 4 to get the 4%. Add the 80% and the 4% to get your answer. I really hope this helps. answers

the mean number of emails adele received during a week was 51.
The numbers received for the six days were 39, 57, 70, 45, 71, 32.Find how many emails she received on the seventh day. ​

Answers

Given:

The mean number of emails adele received during a week was 51.

The numbers received for the six days were 39, 57, 70, 45, 71, 32.

To find:

The number of emails received on the seventh day.

Solution:

Let x be the number of emails received on the seventh day.

We know that,

[tex]\text{Mean}=\dfrac{\text{Sum of observations}}{\text{Number of observations}}[/tex]

[tex]51=\dfrac{314+x}{7}[/tex]

Multiply both sides by 7.

[tex]357=314+x[/tex]

Subtract 314 from both sides.

[tex]357-314=x[/tex]

[tex]43=x[/tex]

Therefore, she received 43 emails on the seventh day.

A student takes 1.5 hours to complete her midterm. How many seconds did it take her to finish the assessment?

Answers

Answer: 5,400 seconds

Explanation: 1.5 hours is equal to 90 minutes and there is 60 seconds in a minute all you have to do is multiply 90 x 60 hope this helped(:

The student took 5400 seconds to finish her assessment.

Given,

A student takes 1.5 hours to complete her midterm.

We have to find how many seconds it took to finish her midterm assessment.

How many seconds in an minute?

One hour = 60 minutes

1 minute = 60 seconds

We have,

A student takes 1.5 hours to complete her midterm.

1.5 hours = to complete the assessment.

Converting 1.5 hours into seconds.

1 minutes = 60 seconds

Multiplying 60 on both sides.

60  x 1 minutes = 60 x 60 seconds

60 minutes = 3600 seconds

1 hour = 60 minutes

1 hour = 3600 seconds

Multiplying 1.5 on both sides.

1.5 x 1 hour = 1.5 x 3600 seconds

1.5 hours = 5400 seconds.

Thus the student took 5400 seconds to finish her assessment.

write and solve this equation: Samantha is one year less than twice her brother Jack’s age. If the sum of their ages is 41, how old is Samantha?

Answers

Answer:

Samantha's age = 27 years

Step-by-step explanation:

Let Jack's age be = x

As Samantha is one year less than twice her brother Jack’s age.

So Samantha's age = 2x-1

As the sum of their ages is 41.

Thus, the equation become

x+2x-1 = 41

3x-1 = 41

3x = 42

Dividing both sides by 3

x = 14

It indicates that Jack's age = 14 years

Therefore,

Samantha's age = 2x-1 = 2(14)-1 = 27 years

What is the image of the point (2,3) after the transformation Ry-axis?

Answers

Answer:

The image of the point (2, 3) after the reflection across the y-axis will be: (-2, 3)

Step-by-step explanation:

We know that when a point, let say P(x, y), is reflected across the y-axis, the sign of x-coordinate is reversed but y-coordinate remains the same.

In other words, the rule is:

P(x, y) → P'(-x, y)

Here, P'(x, y) is the image of the original point P(x, y) after the reflection across the y-axis.

Considering the point

A(2, 3)

Let us reflect the point A(2, 3) across the y-axis.

We know the rule:

P(x, y) → P'(-x, y)

so

A(2, 3) → A'(-2, 3)

Thus, the image of the point (2, 3) after the reflection across the y-axis will be: (-2, 3)
