Answer:

x=-120

Step-by-step explanation:

7x-130=110+9x

add 130 to both sides of the equation

7x-130+130=110+9x+130

Simplify

7x=9x+240

Subtract 9x from both sides

7x-9x=9x+240-9x

Simplify

-2x=240

divide both sides by -2

-2/-2=240/-2

simplify

x=-120

Answer:

y

Step-by-step explanation:

A variable is a letter that holds the place of a number. y in this expression matches that description, so it is the variable.

Answer: x>−3

Step-by-step explanation:

Pull out like factors :

  -15 - 5x  =   -5 • (x + 3)

Divide both sides by  -5  

Remember to flip the inequality sign

Subtract  3  from both sides

           x > -3

Step-by-step explanation:

Answer:

3x(2+n)+[7+n]

Step-by-step explanation:

The answer is kind of self-explanatory, but think of it this way.  If n=5, then the equation would be 3x(2+5)+[7+5]. First we would solve 2+5 which is 7. Then we would do 7+5 which is 12. We are now left with 3x7+5.

Answer:

Proportional

Step-by-step explanation:

A proportional graph is a straight line that passes through the origin.

A non-proportional graph can be a straight line, but it does NOT pass through the origin.

Therefore, this is a proportional graph.

Hope this helps :)

Answer:

second row x=0 f(x)=2

Step-by-step explanation:

when x= 0 the f(x) = y-intercept

Second row of the table reveals the y-intercept of function f.

The x-intercept is the point where a line crosses the x-axis, and the y-intercept is the point where a line crosses the y-axis.

According to the question

Y intercept of the function f :

y-intercept is the point where a line crosses the y-axis.

i.e x = 0

Only Second row satisfy this condition .

Hence, Second row of the table reveals the y-intercept of function f.

Answer:

a. x^2 - 1

b. x^2 - 6x + 9

c. [tex]\dfrac{3x + 1}{x^2 + x}[/tex]

Step-by-step explanation:

a.

Answer:

383ft

Step-by-step explanation:

Given parameters:

  Elevation = 240ft at the start

  Elevation at the end = -143ft

Unknown:

Change in elevation:

Solution:

The change in elevation is the difference between the two hiking milestone;

  change in elevation = Elevation at the start  - Elevation at the end

                                    = 240ft  - (-)143ft

                                   = 240 + 143

                                    = 383ft

Answer:

Power settings.

Step-by-step explanation:

In Mathematics, a random variable can be defined as any variable whose values are determined by the outcome of a random experiment.

Basically, random variables are classified into two (2) main categories and these are; continuous and discrete random variable.

A discrete random variable is a data set in which the number of possible values are either finite or countable. For example, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.

In this scenario, an appliance store sells microwave ovens and has many different styles to choose from. A handout from the store contains details about brand, type (countertop or over-range), number of power settings, and color.

Hence, the variable which is a discrete quantitative variable is the number of power settings because its values are countable or finite, usually it ranges from 100 to 800.

Answer:

Ratio of length of cell A to cell B is 20 : 1

Step-by-step explanation:

Length of cell A = [tex]8\times 10^{-6}[/tex] m

Length of cell B = 0.0000004 m

Convert the length of cell B into scientific notation.

Length of cell B = [tex]4.0\times 10^{-7}[/tex]

Now the ratio of the lengths of cell A and cell B = [tex]\frac{8.0\times 10^{-6}}{4.0\times 10^{-7}}[/tex]

                                                                                = [tex]2\times 10^{7-6}[/tex]

                                                                                = 20

Therefore, ratio of length of cell A to cell B is 20 : 1

Answer:

1. 30(8.75) + 11t = 400

2. 12.5 hours

Step-by-step explanation:

1. What is given is you work for 30 hours per week at a gas station for $8.75 an hour. You also work as a landscaper for $11 an hour. You want to a make a total of $400 per week.

30 hours and $8.75 an hour would be equivalent to 30(8.75)

We don’t know how many hours you work as a landscaper but you earn $11 an hour, which is equivalent to 11t

Finally, you want to earn a total of $400 a week, which means the sum equals 400

30(8.75) + 11t = 400

2. 30(8.75) = 262.5

400 - 262.5 = 137.5

137.5 / 11 = 12.5

Answer:

the value of x is 5/7 which is in fraction

Answer:  x = 5/7

Step-by-step explanation:  2x/3 + x/2 =5/6

To use a least common denominator, divide LCD by the original denominator and multiply the original numerator by the result.

for 2x/3  6÷3=2  2×2x=4x so that becomes 4x/6

for x/2    6÷2=3  3× (invisible) 1 = 3x, so that becomes 3x/6

combine 4x/6 + 3x/6 = 7x/6  

Back to the original equation, substituting the calculated term:

7x/6 = 5/6   Multiply both sides by 6 to simplify (6)(7x/6) = (6)(5/6) 6's "cancel"

7x = 5 .  Divide both sides by 7 to solve for x  7x/7 = 5/7

x = 5/7
