Answer: $12.87
Step-by-step explanation:
You need to set up your equation. We are trying to find x.
Step 1: [tex]\frac{x}{39} = \frac{33}{100}[/tex]
Step 2: Multiply across: 39 x 33 divided by 100.

whats slope intercept form for 2x- 5y=10
Answer:
y=-2/5x-2
Step-by-step explanation:
First, you put x to the other side of the equation so you get y alone, getting the equation of -5y=-2x+10. In order to just have y on one side, you need to divide the whole equation by -5. This leads to the final answer of y=-2/5x-2.

What are the Coordinates?Coordinates are the set of points in a geometrical plane or space, which is used to denote the exact point in the coordinate plane or space.
Given a line segment with the given coordinates for the end points.
Midpoint of a segment with end points (x, y) and (x', y') is,
Midpoint = ((x + x') / 2, (y + y') / 2)
Here the end points of the segment are (-6, -2) and (-1, 5).
Midpoint of the segment = ((-6 - 1) / 2, (-2 + 5) / 2)
= (-7/2, 3/2)
Hence the mid point of the segment is (-7/2, 3/2).

Determine whether each number is a solution of the
given inequality.
6-n > 11
when n = -5
O YES (n = -5 is a solution of the inequality)
O NO (n = -5 is not a solution of the inequality)
Answer:
NO (n = -5 is not a solution to the inequality).
Step-by-step explanation:
Given
[tex]6-n-6>11-6[/tex]
Subtract 6 from both sides
[tex]6-n-6>11-6[/tex]
Simplify
[tex]-n>5[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\left(-n\right)\left(-1\right)<5\left(-1\right)[/tex]
Simplify
[tex]n<-5[/tex]
Therefore, n = -5 is NOT a solution of the inequality because 'n' must be less than -5.
Hence,
NO (n = -5 is not a solution to the inequality).
Verification:
Given
[tex]6-n-6>11-6[/tex]
substitute n = -5
6 - (-5) - 6 > 5
6+5-6 > 5
5 > 5

Which equation below does NOT represent a function?
A
y = -4
B
y = x2 + 1
C
x2 + y2 = 6
D
y = 2x + 5
Answer:
C
Step-by-step explanation:
x2+y2=9 is an example of a non function because there is at least one x value with two or more y values .
The equation below does NOT represent a function is D x² + y² = 6
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) .
x² + y² = 9 is an example of a non function because there is at least one x value with two or more y values .
Now, y = 4
y = x - 4
y = x^2 - 4
Also, x² + y² = 6
This is not a function as there should be minimum one x value with two or more y values. this equation does not meet the criteria so this represent non-function.

Will is w years old.
Ben is 3 years older.
1. Write an expression, in terms of w, for Ben's age.
Jan is twice as old as Ben.
2. Write an expression, in terms of w, for Jan's age.
If you add together the ages of Will, Ben and Jan the total comes to 41 years.
3. Form an equation and solve it to work out how old Will, Ben, and Jan are.
Answer:
Will is 8 years old, Ben is 11 years old, and Jan is 22 years old
Step-by-step explanation:
Since Ben is 3 years older, his age can be represented by w + 3
Jan is twice as old as Ben, so her age can be represented by 2(w + 3)
Set up an equation that adds up these expressions and sets it equal to 41:
(w) + (w + 3) + 2(w + 3) = 41
Simplify, add like terms, and solve for w:
(w) + (w + 3) + 2(w + 3) = 41
(w) + (w + 3) + (2w + 6) = 41
4w + 9 = 41
4w = 32
w = 8
So, Will is 8 years old.
Find Ben's age by adding 3 to this:
8 + 3
= 11
Find Jan's age by multiplying this by 2:
11(2)
= 22
So, Will is 8 years old, Ben is 11 years old, and Jan is 22 years old

Write the sum, and then write an equivalent expression by collecting like terms and removing parentheses
b. 2x - 7 and the opposite of 2x
Step-by-step explanation:
We need to write the sum of 2x - 7 and the opposite of 2x
Opposite of 2x is (-2x)
Sum means to add the number :
2x-7 + (-2x)
Remove parentheses,
2x-7 - 2x
Taking like terms together,
2x-2x-7= 0-7
= -7
Hence, the answer is -7.

Ethan is planning flowers in boxes East flower box can hold 4 Ethan wants to plan 38 red flowers and 33 white flowers in the flower boxes what is the fewest number of flower boxes he would need to plant all the flowers
Answer:
18 flower boxes
Step-by-step explanation:
Given that:
Capacity of each flower box = 4
Number of flowers to plant :
Red = 38
White = 33
Total = (38 + 33) = 71 flowers
Fewest number of flower boxes needed to plant all flowers :
Total flowers to plant / capacity of each plant
71 / 4
= 17.75
= 18 boxes
