18 white and 27 black
Step-by-step explanation:
add 2 + 3 to get 5
45 ÷ 5 = 9
since white is 2, multiply 9 by 2 to get 18
since black 3, multiply 9 by 3 to get 27
What is the slope & y-intercept for
y= -2x - 5 ?
Answer:
Slope = 2, and y intercept = -5
Answer:
The overall equation for slope-intercept is
y = mx + b
M would equal slope
B would be equal y-intercept.
So, judging from both equations now,
-2 is slope, while y-intercept is -5
If you are confused on why the y-intercept is -5 I will answer it for you. Have a good day ^-^

y varies directly as x, if y = 9, when x = -3, find x when y = -27
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

Friday night a pizza parlor sold 5 large pizzas and some medium pizzas the pizza parlor made a totle of 291 how many mediom pizas werer sold wright and eqacion
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
He sold 24 medium pizza

The measure of an exterior angle of a triangle is x. The measure of the adjacent interior angle is at least twice x. List three possible solutions for x.
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°
does anyone know how to do this by solving with substitution
Answer:
Step-by-step explanation:
Question 1
System of equations is,
y = -6x -------(1)
y = -4x - 2 ---------(2)
Substitute the value of y from equation (1) to equation (2)
-6x = -4x - 2
-6x + 4x = -2
-2x = -2
x = 1
From equation (1)
y = -6(1)
y = -6
Question (2)
System of equations is,
-y = x --------(1)
3x + 5y = 20 ---------(2)
Substitute the value of x from equation (1) to equation (2)
3(-y) + 5y = 20
-3y + 5y = 20
2y = 20
y = 10
From equation (1)
-y = x
x = -10
Question (3)
System of the equations is,
y = -2x - 7 --------(1)
9x - 10y = 12 ----------(2)
Substitute the value of y from equation (1) to equation (2)
9x - 10(-2x - 7) = 12
9x + 20x + 70 = 12
29x = 12 - 70
29x = -58
x = -2
From equation (1)
y = -2(-2) - 7
y = 4 - 7
y = -3

Given that a = ( − 6 7 ) and b = ( − 1 − 3 ) . If a − b = ( x y ) , work out the values of x and y .
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

Expand 3(x+ 2.3)
Expand 1/3(9x-12)
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

Step-by-step explanation:
how can you represent all of the solutions to systems of inequalities?
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.
