28 students picked pizza the the 12 students picked the burgers what percentage of the students picked the pizza

Answer:A closed, or shaded, circle is used to represent the inequalities greater than or equal to (≥) or less than or equal to (≤) . The point is part of the solution. An open circle is used for greater than (>) or less than (<). The point is not part of the solution. Solving" systems of linear inequalities means "graphing each individual inequality, and then finding the overlaps of the various solutions". So I graph each inequality, and then find the overlapping portions of the solution regions.Step 1: Line up the equations so that the variables are lined up vertically. Step 2: Choose the easiest variable to eliminate and multiply both equations by different numbers so that the coefficients of that variable are the same. Step 3: Subtract the two equations. Step 4: Solve the one variable system.

Answer:

9

Step-by-step explanation:

x Is -1/3 of y

-27x-1/3= 9

The value of x when y = -27 is 9.

y varies directly as x

Therefore,

y ∝ x

y = kx

where

k = constant of proportionality

Let's find k when y = 9 and x = -3

y = kx

9 = -3k

k = 9 / -3

k = -3

Let's find x when y = -27

y = kx

-27 = -3x

x = -27 / -3

x = 9

Answer:

[tex]2(x+7)[/tex]

Step-by-step explanation:

Factoring is when takes out the GCF (greatest common factor) between two numbers. Between the numbers [tex]( 2x + 14 )[/tex] The GCF is ([tex]2[/tex]). Hence one divides both numbers by ([tex]2[/tex]), groups the numbers and then writes ([tex]2[/tex]) on the outside.

The decimal is 8.44444

Decimals are a set of numbers lying between integers on a number line. They are just another way to represent fractions in mathematics. With the help of decimals, we can write more precise values of measurable quantities like length, weight, distance, money, etc. The numbers to the left of the decimal point are the integers or whole numbers and the numbers to the right of the decimal point are decimal fractions. If we go right from ones place, the next place will be (1/10) times smaller, which will be (1/10)th or tenth place value.

Answer:

3x+6.9 and 3x-4

Step-by-step explanation:

since 3 x x is 3x and the sign in the bracket is addition you place it there then place 3 x 2.3

being 6.9.

1/3 x 9is 9/3 and 3 can multiply both sides to get 3/1 or 3 then bring the minus and 1/3 x 12 is 12/3 3 can multiply both sides to get 4/1 or 4

Answer: 24

Step-by-step explanation:

The other information regarding the question is that the Medium pizza cost $9 while the Large pizza cost $15.

The number of medium sized pizza that Wright sold will be represented by x.

(5 × $15) + ($9 × x) = $291

$75 + 9x = $291

9x = $291 - $75

9x = $216

x = $216/9

x = 24

Answer:

x=60°

x=48°

x=21°

Step-by-step explanation:

Inequalities

The sum of the exterior and the interior angle of a triangle is 180°.

The measure of an exterior angle of a triangle is called x, thus the interior angle is 180-x.

This angle is said to be at least twice x, thus:

180 - x ≥ 2x

Adding x:

180 ≥ 3x

Dividing by 3:

60 ≥ x

Swapping the inequality:

x ≤ 60°

The measure of x must be less or equal to 60°.

Three possible solutions are:

x=60°

x=48°

x=21°

Answer:

x = -5 , y = 10

Step-by-step explanation:

As given ,

a = ( x₁ , y₁ ) = ( -6, 7)

b = ( x₂ , y₂ ) = (-1, -3)

For a -b = ( x₁ - x₂ , y₁ - y₂ )

            = ( -6 - (-1) , 7 - (-3) )

            = ( -6 + 1 , 7 + 3 )

            = ( -5 , 10 )

⇒ a - b = ( -5, 10 ) = ( x, y)

∴ we get

x = -5 , y = 10
