please help me asapppppp

x / 2 - 1 = 3

Add 1 to both sides.

x / 2 = 4

Multiply both sides by 2.

x = 8

Now lets put in 8 for x in our original equation:

8 / 2 - 1 = 3

4 - 1 = 3

3 = 3

This is correct, therefore we know x = 8.

I hope I've helped! :)

Step-by-step explanation:

The Inaquality Notation should be ( x < - 3 ), you have it right but need to turn the arrow around or you can put in another form. ( x > 0 ) with line under the arrow.

Answer:

123

Step-by-step explanation:

First of all, you have to find the total amount of people surveyed, so you add 82+105+141, which would be 328. Then you have to find 37.5% of 328, which is 123 only childs that have no pets.

3/10

Answer:

a= 18; b= 48; c= 88. Please note that even half these value work (9, 24, 44) or any multiple of these (9k, 24k, 44k, with k a positive integer)

Step-by-step explanation:

Let's go easy, and pick b to be 6x8, to make things easy for us. Maybe even 6x4 could work, 12x8 will totally work, but this is the simplest choice.

Now on the first proportion [tex]a:48=3:8 \rightarrow 8a = 48\times3 \rightarrow a = 18[/tex]

From the second proportion [tex]48:c=6:11 \rightarrow 6c = 48\times 11 \rightarrow c = 88[/tex]

Answer:

66 mph

Step-by-step explanation:

w = e - 18

2w + 2e = 300

2 (e - 18) + 2e = 300

2e - 36 + 2e = 300

4e - 36 = 300

4e = 300 + 36 = 336

e = 84 mph

w = 66 mph

The westbound train is travelling at 66 mph

Answer:

50

Step-by-step explanation:

Looks like a  typo in the question

To get the unit rate, divide the miles by the hours

Unit rates

1000 miles in 2 hours = 1000/2 = 500

I'm guessing you meant 100 miles not 1000 miles

100 miles in 2 hours = 100/2 = 50

Answer:

there are 7x girls, so 7x = 2x+250 5x=250

Step-by-step explanation:

Answer:

Step-by-step explanation:

The usual definition of pi is the ratio of the circumference of a circle to its diameter, so that the circumference of a circle is pi times the diameter, or 2 pi times the radius. The animation above shows that a circle can be cut and rearranged to closely resemble a parallelogram (with height r and base pi times r) of area pi times the square of the radius. By dividing the circle into more than eight slices, the approximation obtained in this manner would be even better. By dividing the circle into more and more slices, the approximating parallelograms approximate the area of the circle arbitrarily close. This give a geometric justification that the area of a circle really is "pi r squared".

Answer:

1.) y = 4/3x + (-5)

Answer:

y = - 7

Step-by-step explanation:

Answer:

A) 1, 4, 5, 9, 14, 23, 37

B) 2, 4, 6, 10, 16, 26, 42

Step-by-step explanation:

1. The Fibonacci sequence states that each number is the sum of the two numbers before it.

2. Given the information above, let's solve the question.

-> A: 9 + 14 = 23, 14 + 23 = 37

-> B: 10 + 16 = 26, 16 + 26 = 42

Therefore, the answer is:

A) 1, 4, 5, 9, 14, 23, 37

B) 2, 4, 6, 10, 16, 26, 42

Answer:

amplitude = 2

Step-by-step explanation:

Given

y = a cosbx

amplitude = | a | , period = [tex]\frac{2\pi }{b}[/tex]

y = 2cos2∅

with amplitude = | 2 | = 2

Answer:

[tex]\displaystyle 2[/tex]

Step-by-step explanation:

[tex]\displaystyle y = Acos(Bx - C) + D \\ \\ Vertical\:Shift \hookrightarrow D \\ Horisontal\:[Phase]\:Shift \hookrightarrow \frac{C}{B} \\ Wavelength\:[Period] \hookrightarrow \frac{2}{B}\pi \\ Amplitude \hookrightarrow |A|[/tex]

With the above information, you should now tell what the amplitude value is.

Answer:

6/1 or just 6

Step-by-step explanation:

Answer:

6 over 1 is the slope

Step-by-step explanation:

to find the slope of a line you have to find two points on the line and do rise over run

so for example for this problem I looked at the tho points and starting from the bottom one I went up (rise) six and over (run) one and got 6 over 1

Answer:

30°

Step-by-step explanation:

as sum of angles = 180°

so 180° -(90° + 60°) = 30°

[tex]\qquad[/tex] ☀️It's given,One angle of a right triangle measures 60°.

[tex]\qquad[/tex] According to the question :-

[tex]\qquad \longrightarrow {\purple {\underline{\underline{\pmb{\sf{ Sum_{(All \:angles) }= 180°}}}}}}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow 60° + 90° + x = 180°}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow 150° + x = 180°}[/tex]

[tex]\qquad \pmb{\sf\longrightarrow x = 180° - 150°}[/tex]

Answer:

Yes, with some change to spare.

Step-by-step explanation:

He has 20$. Take 1/5 of it, it's 4$ (because 4x5 = 20), so he will be left with 16$. He owes less than this, 15$, so he can repay his debt in full and have still 1$ left.

Answer:

  1/2

Step-by-step explanation:

It usually works well to compute the slope from coordinates where the graph crosses grid line intersections. We can identify two of those as ...

  (-1, 3) and (1, 4)

The slope formula tells you the slope is ...

  m = (y2 -y1)/(x2 -x1)

  m = (4 -3)/(1 -(-1)) = 1/2

The slope of the line is 1/2.

Additional comment

The y-intercept is 3 1/2.

An equation for the line could be ...

  y = 1/2x + 3 1/2 . . . slope-intercept form

  x -2y = -7 . . . . . . . . standard form
