The answer to the given questions are b = 54, c = 24, m = 75, y = 33, p =87.
What happens to a number or a variable when it is being moved from one side of the equation to the other side ?It changes it's sign.
We have to form equation for the given questions with a variable and find the value of the variable.
In the first question
There were 45 apples in the barn her dad picked some more apples and put them into it and now the total no. of apples in the barn is 99.
Assuming here dad picked b no. of apples the the equation will be of the form
45 + b = 99
b = 99 - 45
b = 54.
∴ Her dad put 54 apples in the barn.
In the second question
Gran sold 13 clothes in the sell and after that she had 11 clothes left and c is the total no. of clothes
∴ c = 13 + 11
c = 24
So Gran knitted 24 clothes for her school fundraiser.
In the third question
leah's friend gave her 12 dollars for her birthday and after her grandparents gave her some money (m) she had a total of
87 dollars.
∴ 12 + m = 87
m = 87 - 12
m = 75
So her grandparents gave her 75 dollars of money.
In the fourth question
Lorenzo had 96 passing yards before the football game and after that he had 129 yards for the season and y be the no. of passing yards during the football game.
∴ 96 + y = 129
y = 129 - 96
y = 33.
So he made 33 passing yards during the game.
In the fifth question
An artist took 105 art pieces and after he sold some of them which is p he is left with 18 pieces
∴ 105 - p = 18
p = 105 - 18
p = 87
So he sold 87 pieces of art in the fair.

Answer:
1. 157 in³
2. 12 in
3. volume of the rice container is 1.5 times the volume of the sugar container
4. 50.24 in³
5. Rice container has the greatest volume
Flour container has the smallest volume
Step-by-step explanation:
By inspection of the diagram, the three containers are all cylinders.
Volume of a cylinder = [tex]\pi r^2h[/tex]
(where r is the radius and h is the height)
Given [tex]\pi[/tex] = 3.14
1. volume of sugar container = 3.14 x 2.5² x 8 = 157 in³
2. 235.5 = 3.14 x 2.5² x h
⇒ 235.5 = 19.625h
⇒ h = 235.5 ÷ 19.625 = 12 in
3. height of sugar container = 8 in
height of rice container = 12 in
12 ÷ 8 = 1.5
⇒ height of rice container is 1.5 times the height of the sugar container
volume of sugar container = 157 in³
volume of rice container = 235.5 in³
235.5 ÷ 157 = 1.5
⇒ volume of the rice container is 1.5 times the volume of the sugar container
4. volume of flour container = 12.56 x 4 = 50.24 in³
5. volume of sugar container = 157 in³
volume of rice container = 235.5 in³
volume of flour container = 50.24 in³
Rice container has the greatest volume
Flour container has the smallest volume

What is the equation for the graph shown?
Answer:
y = 2x/3 + 4
Step-by-step explanation:
The line passes through (-6, 0) and (0, 4)
slope = (4 - 0)/(0 - (-6)) = 4/6 = 2/3
y = (2/3)x + b
when x = 0, y = 4, so
4 = (2/3)*0 + b
b = 4
so
y = 2x/3 + 4

R is
3.8/2.2=19/11Its greater than 1 .
So diverge series.Answer:
[tex]r=\dfrac{12}{7}[/tex]
series diverges
Step-by-step explanation:
To find the common ratio (r) of a geometric series, divide the (n+1)th term by the nth term.
When n = 1:
[tex]a_1=\dfrac{3^{1+1}}{3(1)+1}=\dfrac{3^2}{4}=\dfrac94[/tex]
When n =2:
[tex]a_2=\dfrac{3^{2+1}}{3(2)+1}=\dfrac{3^3}{7}=\dfrac{27}{7}[/tex]
Therefore,
[tex]r=\dfrac{a_2}{a_1}=\dfrac{\frac{27}{7}}{\frac{9}{4}}=\dfrac{12}{7}[/tex]
A series that converges has a finite limit. If |r| < 1, then the series will converge.
A series that diverges means either the partial sums have no limit or approach infinity. If |r| > 1 then the series diverges.
Therefore, as the limit of the series approaches infinity and it's r value is greater than 1, the series diverges.

If a salesman averages a new order every other week, he will break the office record for the year. However, after 32 weeks he is four orders behind schedule. In what proportion of the remaining weeks does he have to obtain a new order to break the record?
The proportion of remaining weeks that he has to obtain a new order to break the record is: 0.7 = 70%.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
He needs a new order every other week, that is, 0.5 orders per week, hence over one year = 52 weeks, the number of orders is:
O = 0.5 x 52 = 26 orders.
Over the first 32 weeks, the expected number was:
E = 0.5 x 32 = 16.
He was four orders behind schedule, that is, he had 12 orders, hence he needed 26 - 12 = 14 orders in the remaining 52 - 32 = 20 weeks, hence the proportion is:
p = 14/20 = 0.7.

Use a net to find the surface area of the right triangular prism shown:
Answer:
256 ft²
Step-by-step explanation:
Net comprises: 2 equal triangles, 2 equal rectangles and 1 smaller rectangle
Area of a triangle = 1/2 x base x height
⇒ area of one triangle = 1/2 x 10 x 7 = 35 ft²
Area of a rectangle = width x length
⇒ area of larger rectangle = 6 x 12 = 72 ft²
⇒ area of smaller rectangle area = 6 x 7 = 42 ft²
⇒ Total area = (2 x 35) + (2 x 72) + 42 = 256 ft²

Answer:
-3.5 14
Step-by-step explanation:
2y=-7x+28
y=-3.5x+14
Answer:
Y-intercept = (0, 14) and Slope = -7/2
Step-by-step explanation:
7x + 2y - 15 = 13
2y = -7x + 28
y = -7/2x + 14
Slope = -7/2
Y-intercept = (0, 14)
Can someone explain the three solutions in math: one solution, no solution, and all real numbers please. What does it mean when then the statement is false how do I know when it’s false?I’m confused I don’t know how to identify the solutions please help me thank you so much!!!
Step-by-step explanation:
Note that when lines intersect, that when they show a solution.
All Solutions:
When we graph two equations, and they line on the same curve thus all points will be a point of intersection..
Let say we have two linear equations.
[tex]4x + 4y = 16[/tex]
[tex]x + y = 4[/tex]
This are all solutions, because
if we do the graphical way, when we graph this on a calculator or desmos, they will lie on the same curve so it has infinite points of intersections.
If we do algebraic way,
Notice that the top equation is the same as The bottom equation but just multiplied by 4. So the top and bottom equations are the same.
So whenever the two or more equations have same slope and same y intercept, the solutions will be all real solutions or infinite solutions.
One Solution:
In plane geometry, note that a line that isn't parallel to another one, will intersect eventually once.
This means that for example
[tex]4x + 4y = 16[/tex]
[tex]x + 2y = 32[/tex]
These equations have different slope so they will intersect once. Which means it'll have one solution.
NO Solutions:
Parallel Lines never intersect which means they have no solutions.
Consider this
[tex]4x + 4y = 16[/tex]
[tex]x + y = 1[/tex]
We know the slopes are the same but y intercept is different they will never intersect.

Answer:
-5/4
Step-by-step explanation:
We can use the slope formula to find the slope
m = ( y2-y1)/(x2-x1)
= ( -3 -2)/( 3 - -1)
= ( -3-2 ) /( 3+1)
= -5/4
Answer:
m = -5/4
Step-by-step explanation:
The slope formula is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].
[tex]\frac{(-3)-(2)}{3-(-1)}[/tex] [tex]\frac{-5}{3+1}[/tex] [tex]\frac{-5}{4}[/tex]Therefore, m = -5/4.

27 is 30% of what number?
Answer:
im pretty sure that the answer your looking for is 90
Step-by-step explanation:
Answer:
90
Step-by-step explanation:
STEP 1 27 = 30% × Y
STEP 2 27 = 30/100 × Y
Multiplying both sides by 100 and dividing both sides of the equation by 30 we will arrive at:
STEP 3 Y = 27 × 100/30
STEP 4 Y = 27 × 100 ÷ 30
STEP 5 Y = 90
Finally, we have found the value of Y which is 90 and that is our answer.
