Answer:

x=6

Step-by-step explanation:

Simplifying

x + 15 = 21

Reorder the terms:

15 + x = 21

Solving

15 + x = 21

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + x = 21 + -15

Combine like terms: 15 + -15 = 0

0 + x = 21 + -15

x = 21 + -15

Combine like terms: 21 + -15 = 6

x = 6

Simplifying

x = 6

See the explanation

Step-by-step explanation:

Given data

Gym A charges $60 a month plus $5 per visit

let the number of visits be x, and the total charge be y

Hence the total charge is expressed as

y=5x+60--------------1

Gym B is represented by

y = 7x + 40-----------2

Although I can not find any option, we can conclude that gym A monthly charge is $20  more expensive than gym B

Answer:

28%

Step-by-step explanation:

The result is about 27.5362% so if we round it it will be 28%

Answer:  28%

Step-by-step explanation:

1.15x12=13.8

13.8-10.00=3.8

3.8/13.8=0.27536231884

To convert to percent 0.27536231884 * 100= 27.536231884 rounded 28

Answer:

the greatest number and the smallest number be 3 and 7 respectively

Step-by-step explanation:

Let us assume the greater number x and the smaller number be y

Now according to the question, following equation should be made

1 ÷2 (x - y) = 2

x - y = 4 ..................... (i)

And,

x + 2y = 13 ................(ii)

Now solve both the equations

-3y = -9

y = 3

Now x is

x - y = 4

x - 3 = 4

x = 7

Hence, the greatest number and the smallest number be 3 and 7 respectively

Answer:

45 degrees

Step-by-step explanation:

The sum of all angles is 180 degrees. Since we know one is 43, we subtract it from 180. 180 - 43 is 137.

The angle with the 88 degrees next to it is supplementary to the given angle, which means the measurement of the angle next to 88 is 180 - 88, which is 92 degrees.

143 - 92 is 45. Hope this helps

Answer:

length 60 feet

length 2=60 feet

width 1=30feet

width 2=30feet

those is because there is 4 sides to a rectangle

Step-by-step explanation:

because the length is twice the width, 2x 30=length

Given:

The linear equation is:

[tex]2x+2y=2[/tex]

To find:

The statement that best describes the graph of the given linear equation.

Solution:

The slope intercept form of a linear function is:

[tex]y=mx+b[/tex]            ...(i)

Where, m is the slope anf b is the y-intercept.

We have,

[tex]2x+2y=2[/tex]

It can be written as:

[tex]2y=2-2x[/tex]

[tex]y=\dfrac{2-2x}{2}[/tex]

[tex]y=1-x[/tex]

[tex]y=-x+1[/tex]             (ii)

On comparing (i) and (ii), we get

[tex]m=-1,b=1[/tex]

Therefore, the graph has a slope of -1 and a y-intercept of 1. Hence option D is correct.

Answer:

Slope: 10

y-intercept: (0,0)

Answer:

Y-intercept is 0 and slope is 10x

Y = 10x - 0

Answer:

B)1,200

Step-by-step explanation:

If you add up the close at 10pm numbers you get 60. Since the total number of people surveyed was 200 and the question asks if there were 4,000 you would divide 4,000 by 200 and you would get 20. Then you should multiply 60 by 20.

Answer:

Miguel

Step-by-step explanation:

What we know:

Miguel ate 3/4 of his sandwich.

Annie ate 5/8 of her sandwich.

First we have to make the denominators equal.

3/4×2=6/8

6 is bigger than 5 so it would be 6/8 or 3/4 and Miguel ate 3/4.

Answer:

60 different possibilities

Step-by-step explanation:

Number of bikers = 5

Positions = first, second and third

First positions = all 5 riders can take the first spot = 5 possibilities

Second spot = position 1 has been filled hence number of possibilities = ( 5 - 1) = 4

Third spot = position 1 and 2 has been filled ; number of possibilities =. (5 - 2). = 3

Number of possible arrangements :

5 * 4 * 3 = 60 different possibilities

Answer:

C. Are all real numbers greater than or equal to -8.

Step-by-step explanation:

Real numbers can be said to be all continuous values of quantity, which can be negative or positive values.

The range of h, h(x), in the table given are all real numbers.

The least of the range of h on the table is -8. All the other range values, namely, -7, 1, 17, and 41 are all greater than -8. None is less than -8.

Therefore, we can conclude that the range values of h "are all real numbers greater than or equal to -8".

Answer:

over the five years Mr. Amari will have gained 30$

Step-by-step explanation:

Answer:

y < 4/3x - 2

Step-by-step explanation:

Another way to find slope is to subtract  [tex]\frac{y_{1}-y_{2} }{x_{1} -x_{2} }[/tex]. We are given two points. We can subtract the two y-values from each other for the numerator, then do the same for the x-values in the same order for the denominator.

We subtract the y-value 2 from -6.

2 - - 6 can also be taken as 2 + 6.

2 + 6 = 8.

Then, subtract the x-values.

Subtract 3 - -3, or 3 +3.

3 + 3 = 6.

Our slope, then, is [tex]\frac{8}{6}[/tex]. We can simplify this to [tex]\frac{4}{3}[/tex].

Now we can find our y-intercept. The line intersects with the y-axis at the point (0, -2)

The shading is on the left side and the line is dotted, so our sign is <.

The inequality is y < 4/3x -2.
