Answer:    x = 3

Step-by-step explanation:

x+5 = 3x-1

+1           +1

x+6 = 3x

-x       -x

6 = 2x

/2     /2

3 = x

Answer:

x-3x=-1-5

-2x=-6

-2x/-2=-6/-2

x=3

Answer: True

Step-by-step explanation:

Cost = 15 + 3t

22.5 = 15 + 3(2.5)

22.5 = 15 + 7.5

22.5 = 22.5 <— true

Answer:

true

Step-by-step explanation:

2.50 x 3 = 7.50

15 + 7.50 = 22.50

22.50 = 22.50

Answer:

60

Step-by-step explanation:

The whole thing is 180 so if you subtract 180 from 120 you get 60.

Answer:

60 degrees since a straight line is 180 degrees

Step-by-step explanation:

Since part of it is 120 degrees the other part must be 60 because 120 + 60 = 180

Answer:

range : {0, 2, 4}

Answer:

The image point of (-7, 1) after reflection across the y-axis is:

Step-by-step explanation:

When a point P(x, y) is reflected across the y-axis, we reverse the sign of the x-coordinate while the y-coordinate remains the same.  

Thus,  

The rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

In our case, we are given the point (-7, 1)

Let say the point is A(-7, 1).

Thus, using the rule to reflect a point across the y-axis is:  

P(x, y) → P'(-x, y)

A(-7, 1) → A'(-(-7), 1) → A'(7, 1)

Therefore, the image point of (-7, 1) after reflection across the y-axis is:

Answer:

y=x+5

Step-by-step explanation:

you not subtracting, your adding five

the output is x+5 so whatever you input into the x, you add 5

Step-by-step explanation:

Assuming that 23 is the first term

4823

25th term of arithmetic sequence is 4,823

Given arithmetic sequence:

23, 223, 423, 623,...

Find:

25th term of arithmetic sequence

Computation:

First term a = 23

Common difference d = A2 - A1

Common difference d = 223 - 23

Common difference d = 200

Number of term n = 25

So,

An = a + (n - 1)d

A25 = 23 + (25 - 1)(200)

A25 = 23 + (24)(200)

A25 = 23 + 4,800

A25 = 4,823

Answer:

Step-by-step explanation

x+38=2(x+14)

The man is 38 and daughter is 14. They both will age in same years (x).

So, in how many years(x) will they both age until man is equal(=) to 2 times his daughters age?

x+ 38=2(x+14)

x+38=2x+ 28

10= x

In 10 years, the man will be 2twice as old as his daughter.

Answer:

The blank in the equation is 1.

x = 7 and the vertical angles measure out to 64 degrees.

Step-by-step explanation:

When solving for x, you always want to keep the variables on one side. So you'll subtract 9x from both sides. That gives you 1=3x-20. Then you'll add 20 to both sides. This gives you 21=3x. After you'll divide by 3 on both sides. This gives you 7=x.

Now you'll plug in 7 for x. This gives you 12*7-20=9*7+1. First, you'll multiply which gives you 84-20=63+1. Add and you'll get 64 on both sides.

Answer:

x ≈ - 5.32, x ≈ 1.32

Step-by-step explanation:

Given

x² + 4x - 7 = 0 ( add 7 to both sides )

x² + 4x = 7

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(2) x + 4 = 7 + 4

(x + 2)² = 11 ( take the square root of both sides )

x + 2 = ± [tex]\sqrt{11}[/tex] ( subtract 2 from both sides )

x = - 2 ± [tex]\sqrt{11}[/tex]

Then

x = - 2 - [tex]\sqrt{11}[/tex] ≈ - 5.32 ( to 2 dec. places )

x = - 2 + [tex]\sqrt{11}[/tex] ≈ 1.32 ( to 2 dec. places )

Answer:

Area : 27.5

Perimeter : 20

Step-by-step explanation:

All sides of a regular pentagon have the same length

1 side = 4

4x5 = 20 = Perimeter

Pentagon area formula :

1/4(sqrt(5(5+2sqrt(5)))x)

Plug x in (side length)
