Hello I have two questions for my math homework.
The first question is the attachment-
The second questions is- Mr. Candelaria estimates that the drama club sold 400 tickets to the school play. The drama club actually sold 462 tickets. Calculate Mr. Candelaria’s percent error.
TY!!!!
Answers
Answer:
Answers are listed :)
Step-by-step explanation:
1. -81/2 or -40.5
Both answers are correct forms I just didn't know if you wanted fraction or decimal form :)
2. Lots of answers for this one but ill give you mine: Mr. Candeleria probably rounded down his estimate number and in most cases like this you should round up.
Hope this helps :)
The solution is
a) The value of the equation is -40.5 or -81/2
b) Percentage error of Mr.Candelaria in estimating the tickets is 13.42 %
What is Percentage Error?
The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.
Percentage error is the difference between the measured value and the true value , as a percentage of the true value
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Given data ,
a)
Let the equation be represented as A
Now , the value of A is
A = ( 3 4/5 )x - ( 2 1/2 )
On simplifying the equation , we get
A = ( 19/5 )x - ( 5/2 )
when x = -10 , substitute the value of x = -10 , we get
A = ( 19 × -2 ) - 5/2
A = -38 - 5/2
A = -81/2
A = -40.5
Therefore , the value of A is -40.5
B)
The measured value = 400 tickets
The true value = 462 tickets
Now , the percentage error in estimating the tickets by Mr. Candelaria is given by the formula ,
Percentage Error = [ ( | Measured Value - True Value | ) / True Value ]x 100
Substituting the values in the equation , we get
Percentage Error = [ | 400 - 462 | / 462 ] x 100
Percentage Error = [ | -62 | / 462 ] x 100
Percentage Error = 0.134199 x 100
Percentage Error = 13.419 %
Therefore , the percentage error is 13.42 %
Hence , the percentage error of Mr.Candelaria in estimating the tickets is 13.42 %

The value of x would be 75 degrees beacuse of corresponding angles on the same line of tranversal.
What are corresponding angles?In literal sense, corresponding means pair wise angles. Like the right corner angles of two triangles etc. But usually we take them as: For two similar figures, the pair by pair similar angles of those two similar figures are called corresponding angles. They are of same measurement.
Given that AD and EH are parallel lines
So Angle GFE is equals to angle FBA.
And angle CBA equals to 180°
Angle FBA = 180°-105°
Angle FBA = 75°
Hence, The value of x would be 75 degrees beacuse of corresponding angles on the same line of tranversal.

What is the equation of this graph?
Answers
Answer (assuming it is allowed to be written in slope-intercept form):
[tex]y = -\frac{2}{3} x + 1[/tex]
Step-by-step explanation:
When knowing a line's y-intercept and its slope, you can write its equation using slope-intercept form, or [tex]y = mx + b[/tex].
1) First, find the slope of the line. Read the graph and look at the two points marked on the line - they are (0,1) and (3,-1). Use the slope formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] , substitute the x and y values of those points, and solve:
[tex]\frac{(-1)-(1)}{(3)-(0)} \\= \frac{-1-1}{3-0} \\= \frac{-2}{3}[/tex]
Thus, the line's slope is [tex]-\frac{2}{3}[/tex].
2) Now, use the slope-intercept formula, [tex]y = mx + b[/tex], to write an equation. Substitute the [tex]m[/tex] and [tex]b[/tex] for real values.
The [tex]m[/tex] represents the slope, so substitute [tex]-\frac{2}{3}[/tex] in its place. The [tex]b[/tex] represents the y-value of the y-intercept, or the point at which the line crosses the y-axis. Looking at the graph, we can see that the line intersects the y-axis at (0,1). Thus, substitute 1 for [tex]b[/tex]. This gives the following equation and answer:
[tex]y = -\frac{2}{3} x + 1[/tex]

X-11 = 8
Answers
First, you have to get x alone by getting rid of the terms next to it. In this case, it’s -11.
To get rid of a term, do the opposite.
So x - 11 + 11 = 8 + 11
Remember to do it on both sides.
x = 19
Why?
You have to get x alone so you have to add 11 to both sides
X-11+11= 8+11
The 11 cancel out on the left and 8+11 equals 19 so x=19
Brown Delivery Company delivers its standard crates using a fleet of vans and trucks. A van can hold up to 20 standard
crates, and a truck can hold up to 35 standard crates. If Brown Delivery Company needs to deliver exactly 270 standard
crates at one time using 12 vehicles, which system of linear equations could be used to determine the number of vans, x,
and the number of trucks, y, needed for this delivery?
x + y = 12
20x + 35y = 270
x + y = 270
20x + 35y = 12
x + y = 12
35x + 20y = 270
x+y = 270
35x + 20y = 12
Answers
Answer:
x + y = 12
20x + 35y = 270
Step-by-step explanation:
Let us represent:
The number of vans = x
The number of trucks = y
From the above question, we are told that:
A van can hold up to 20 standard crates, and a truck can hold up to 35 standard crates. If Brown Delivery Company needs to deliver exactly 270 standard crates at one time using 12 vehicles.
Hence, our system of equations is given as:
x + y = 12..... Equation 1
20 × x + 35 × y = 270
= 20x + 35y = 270...... Equation 2

find the equation of a line that is parallel to the straight line 2x-y=-3 and crosses the x-axis at x=-5
Answers
Answer:
y=2x+10
Step-by-step explanation:
In line equations its helpful to write your line in the form y = ax + b. This helps because a is always the gadient of the line and b is always the y intercept.
In this case it is y=2x+3
All parallel lines have the same gradient. The gradient of this line = 2.
If the line crosses the x axis at x=-5, then when x =-5 y = 0.
If you put all this in the form y =ax + b you get 0 = 2(-5) +b
So all you need to do to find b is rearrange. b = 10.
Therefore your line has gradient 2 and y intercept 10.
y = 2x + 10

slope is 2/3
Step-by-step explanation:
To solve for slope: y2-y1 / x2- x1.
Two points can be (0,50) and (30,70) since they intercept.
70-50 / 30- 0 = 20/30 = 2/3.
The slope is also going 20 units up and 30 units across which gives you 2/3.
