Step-by-step explanation:

any more help just ask

Answer 2
The first expression is true because x+x+x+x= 4x. It is like addition but with a variable. The second isn’t true because 5x= x+x+x+x+x whereas x+5 is x plus five. Not 5x. Hope this helps.

A worker is spray painting doors. It takes LaTeX: \frac{2}{5} 2 5 of a can of spray paint to paint 1 door. The worker has 2 cans of spray paint total. How many doors can the worker paint? Group of answer choices

Answers

Answer:

5 doors

Step-by-step explanation:

Can of spray paint : door painted = 2/5 : 1

The worker has 2 cans of spray paint total.

How many doors can the worker paint?

Let x = number of doors the worker can paint

Can of spray paint : door painted

2 : x

Equate both ratios

2/5 : 1 = 2 : x

2/5 ÷ 1 = 2/x

2/5 × 1/1 = 2/x

2/5 = 2/x

Cross product

2 * x = 5 * 2

2x = 10

x = 10/2

x = 5 doors

The worker can paint 5 doors with 2 cans of spray paint

Y is directly related to X, and Y is 81 when X is 27.

The constant of variation is ___
(there are no answer choices, it's just a type in box so i need an exact answer please! :))

Answers

Answer:

Since x and y are directly related, the equation for their comparison will look like

kx = y

where k is your constant. They give you an instance in the problem where x = 27 and y = 81. Plug this into the above equation and solve for k.

kx = y

k (27) = 81

k = 3

So, the constant of variation is 3.

It’s B homie .Jajejsjdjejdjrjrj

The function with the domain is given by f ( x ) = 2x + 3

What is a function rule?

The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.

A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.

Given data ,

Let the function be represented as A

Now , the value of A is

Let the x values be x = { -7 , -1 , 3 , 4 , 7 )

Let the y values be y = { -11, 1 , 9 , 11 , 17 }

Now , the function is given as  

f ( x ) = 2x + 3   be equation (1)

when x = -7

y = 2 ( -7 ) + 3

y = -11

when x = 7

y = 2 ( 7 ) + 3

y = 17

Hence , the function is f ( x ) = 2x + 3

Sum of them is:

10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 52822a + 22b + 22c = 528a + b + c = 528/22a + b + c = 24

The only option of three different digits with the sum of 24 is 7, 8 and 9

Answer:

The answer is 7, 8 and 9. The Two-digit numbers are: ab, ac, ba, bc, ca, cb

The Sum of them is: 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528

22a + 22b + 22c = 528

a + b + c = 528/22

a + b + c = 24      The only option/options of the three different digits with the sum of 24 is 7, 8 and 9.

A couch costs $350 to make. Before it is sold, it is marked up in price 80% more. How much will the couch cost?​

Answers

Answer:$630

Step-by-step explanation:

What is 80% of 350?

Y is 80% of 350

Equation: Y = P% * X

Solving our equation for Y

Y = P% * X

Y = 80% * 350

Converting percent to decimal:

p = 80%/100 = 0.8

Y = 0.8 * 350

Y = 280

then u add 280 to 350

PLEASE HELP!!! A $950 computeris on sale for 15% off. If sales tax is 6% will this computer cost including tax?

Answers

Answer:

the computer will cost 864.5

Step-by-step explanation:

15% of 950 is 142.5.

950-142.5=807.5

6% of 950 is 57

Answer:

$855.95

Step-by-step explanation:

So We can first multiply the original price by 0.85 becuase its 15 percent off and we’re paying 85 percent of the original price basically.

You’ll get 807.50.

Now to find the sales tax we multiply that by 1.06 becuase the 100 percent is the price now and we’re just adding 6 percent so 1.06, and you’ll get 855.95

So no adding and subtracting and that takes off 2 steps and its way quicker

So the final answer is $855.95

The graphed line shown below is y = 5 x minus 10.

On a coordinate plane, a line goes through (2, 0) and (3, 5).

Which equation, when graphed with the given equation, will form a system that has no solution?

y = -5 x + 10
y = 5 (x + 2)
y = 5 (x - 2)
y = -5 x - 10

Answers

Step-by-step explanation:

For 2 lines to form a system with no real solution, the slope of the lines have to be equal and the y-intercept is different.

Hence the answer is y = 5(x + 2).
