Answer all of these 50 points and brainliest

Answer:

(4,-1)

Step-by-step explanation:

x-4y=8

-4y=-x+8

y=1/4x-2

The solution to the equation x - 4y = 8 is an ordered pair (4,-1).

A solution to an equation is a number that can be substituted for the variable to provide a true number statement.

The equation is given in the question, as follows:

x - 4y = 8

To determine the ordered pair (x,y) of the solution, substitute the value of x = 4 in the equation, and solve for y:

4 - 4y = 8

- 4y = 8 - 4

- 4y = 4

y = - 4/4

Divided by -4 into both sides of the equation, we get

y = - 1

Thus, the solution to the equation is an ordered pair (4,-1).

Answer:

5(I think)

Step-by-step explanation:

Yx4 =20

What (x) 4=20?

5x4=20

Answer:

y = 5

Step-by-step explanation:

set up an equation

y * 4 = 20

now solve using inverse operations

y * 4 = 20

  /4     /4

y = 20 / 4

20 / 4 =5

because

4 * 5 = 20

y = 5

Answer:

D is the right choice and no you cannot fit the pizza inside the box.

Step-by-step explanation:

D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.

Answer:

I believe the answer is D.

Answer:

-17.3

Step-by-step explanation:

Evaluate 5 x + x/2 - 29.4 where x = 11/5:

5 x + x/2 - 29.4 = 5×11/5 - 29.4 + 1/2×11/5

Hint: | Express 5×11/5 as a single fraction.

5×11/5 = (5×11)/5:

(5×11)/5 - 29.4 + (11/5)/2

Hint: | Express (11/5)/2 as a single fraction.

(11/5)/2 = 11/(2×5):

(5×11)/5 - 29.4 + 11/(2×5)

Hint: | Cancel common terms in the numerator and denominator of (5×11)/5.

(5×11)/5 = 5/5×11 = 11:

11 - 29.4 + 11/(2×5)

Hint: | Multiply 2 and 5 together.

2×5 = 10:

11 - 29.4 + 11/10

Hint: | Approximate 11/10.

11/10≈1.1:

11 - 29.4 + 1.1

Hint: | Evaluate 11 + 1.1 using long addition.

| 1 | 1. | 0

+ | | 1. | 1

| 1 | 2. | 1:

12.1 - 29.4

Hint: | Factor out a negative sign in 12.1 - 29.4 in order to subtract.

12.1 - 29.4 = -(29.4 - 12.1):

-(29.4 - 12.1)

Hint: | Subtract 12.1` from 29.4`.

Answer:

950 feet

Step-by-step explanation:

the area of a triangle is a=(bh) 1/2

plug in the values for a triangle into that equation, then do it to the other triangle.

add the solutions to get 150 feet

then find the area of the rectangle: 20 x 40= 800

add 800 and 150 to get the total area: 950 feet

Answer:

Use the graph to write a linear function that relates y to x. The points lie on a line. Find the slope and y-intercept of the line. Because the line crosses the y-axis at (0, −3), the y-intercept is −3.w

Step-by-step explanation:

There are three standard forms for linear functions y = f(x):

f(x) = mx + b (The "slope-intercept" form),

y - yo = m(x - x0) or, equivalently, f(x) = y0 + m(x - x0) (The "point-slope" or "Taylor" form), and.

Ax + By = C (The "general form") which defines y implicitly as a function of x as long as B 0.

Answer:

B. 77

Step-by-step explanation:

because (72 + 97 + 82 + 77) ÷ 4 = 82

Pls Brailniest! ;) It would mean a lot.

Answer:

77

Step-by-step explanation:

If you add all the numbers you would get 251 and if you divide that by 3 you get 83.67. So what I did to get a mean of 82 was add those 3 numbers then the individual answer choice. so 72+97+82+77=328. 328/4 is equal to 82
