The ratio of blue crayons to red crayons in a classroom is 32:28. The classroom has 16 blue crayons.
How many red crayons are in the classroom?
Answer:
14 red crayons
Step-by-step explanation:
since we already know the ratios of the crayons we are going to use ratio and proportion to solve our question B:R is 32:28 and they are directly proportional meaning we can scale the quantities by multiplying.32:28 and 16:R , r is the unknown quantity ,then we cross multiply the 2 ratios to get 32R= 448, then we divide by32 both sides so we can remain with the value of R which is 14

What linear function in form y=Mx+b for the line passing through (4.5,-4.25) with y-intercept 2.5
For us to write the equation for this line, we need to (1) find the slope of the line, and (2) use one of the points to write an equation:
The question gives us two points (one of which is the y-intercept), (4.5,-4.25), and (0, 2.5), from which we can find the slope and later the equation of the line.
Finding the Slope
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (2.5 - (- 4.25)) ÷ (0 - 4.5)
= −1.5
Finding the Equation
Now that we know the slope and the y-intercept, we can write the equation of the line in the point-slope form (y = mx + b)
y = −1.5x + 2.5
Checking my answer:
I used Desmos to graph the line I got and the points. Since the line passes through the points then the line is correct.

1) Delectable Cookie Company sells chocolate chip cookies for $6.95 per pound and
white chocolate cookies for $5.95 per pound. How many pounds of chocolate chip
cookies should be mixed with 4 pounds of white chocolate cookies to obtain a mixture
that sells for $6.75 per pound?
Answer: 16lbs
Step-by-step explanation: CCC=Chocolate Chip Cookie; WCC=White Chocolate Cookie.
Set up a table showing the pricing ($/lb) and pounds (lbs) for both cookies. The total value of the WCC is $23.8 ($5.95/lb x 4 lbs). The value of the CCC is 6.95x, where x is the lbs CCC.
CCC WCC
6.95 5.95 $/lb
x 4 lbs
6.95x 23.8 $ Total value [$/lb * lbs]
We want x lbs of CCC cookies such that the total value of cookies divided by the total number of lbs is equal to $6.75/lb. That can be written as:
(6.95x + 5.95*4)/(x+4) = 6.75 [Total value of cookies divided by total weight equals $6.75]
(6.95x + 23.8)/(x+4) = 6.75
6.95x + 23.8 =6.75x + 27
0.2x = 3.2
x = 16 lbs
We need 16 lbs of CCC added to the 4 lbs of WCC for a total weight of 20 lbs and a price of $6.75/lb.
Find the measure of each marked angle.
Answer:
X= 15, m∠78°
Step-by-step explanation:
Since the angles are vertically opposite
Therefore their measurements are equal
Therefore (2x + 48 ) = (5x + 3 )
So,
[tex](2x + 48) = (5x + 3)\\(2x-5x)= (3-48)\\-3x = -45\\x = -45/-3\\x = 15[/tex]
[tex](2x + 48)\\=( 2* 15 + 48)\\= 30 + 48\\=78\\\\(5x + 3)\\=(5*15 + 3)\\=75+3\\=78[/tex]
They both equal 78°

How do you graph 2x+5
Answer:
Read explanation
Step-by-step explanation:
First you put a point on (0,5). Then you perform rise/run which is the slope. The slope is 2. So from (0,5) you go up 2 and to the right one and make another point. You then use a ruler and draw a line connecting them and put arrows at the end.
In the given figure, the alternate interior angles are
A: 2,1
B: 2,3
C: 2,4
D: 2,5

Answer: sqrt 91
Step-by-step explanation:
We can substitute in y here as 30, so that 60+102=2x^2
182=2x^2
In the order of operations, it states that exponents comes before multiplication
91=x^2
So x will be the square root of 91
Consider the system of equations.
5x + 2y = 12
5x – 2y = 28
What is the solution to the system of equations? Show work using substitution or elimination to support your answer.
A (4, -4)
B (-4, 4)
C (5, -6.5)
D (4, 16)
Show how u got the answer.
Answer:
(4, -4) = (x, y) = A
Step-by-step explanation:
5x + 2y = 12
- (5x - 2y = 28)
4y = -16
y = -4
5x + 2(-4) = 12
5x - 8 = 12
5x = 20
x = 4
What is the slope of the line that passes through (-8, 12) and (4, 3)?
The sum of two numbers is -12.6 identify the two negative addends that make the statement true
The sum of the two numbers = -12.6
The two negative addends that make the statement "The sum of two numbers is -12.6" true are -8.6 and -4
Let x represent the first negative number
Let y represent the second negative number
x + y = -12.6
To make the above equation to be true, assume a value f x that is negative but greater than -12.6
Let x = -8.6
Substitute x = -8.6 into the equation x + y = -12.6
-8.6 + y = -12.6
Add 8.6 to both sides of the equation
-8.6 + 8.6 + y = -12.6 + 8.6
y = -4
As a proof:
-8.6 - 4 = -12.6
The two negative addends that make the statement "The sum of two numbers is -12.6" true are -8.6 and -4
