Two teachers, Mr. Meehan and Mrs. Chipps, decide to buy compasses and rulers for their classrooms. Mrs. Chipps buys 30 compasses and 50 rulers for $95. Mr. Meehan buys 40 of each for $116. What are the individual costs of the compasses and rulers that were purchased? Explanation Please
Answers
Answer:
compass = $ 2.50 each ruler = $ 0.40 eachStep-by-step explanation:
Mrs. Chipps buys 30 c + 50 r = $95
Mr. Meehan buys 40 c + 40 r = $116 x (-1.25) to eliminate r
30 c + 50 r = $ 95
-50 c - 50 r = $-145
-20 c = -50
c = 50 / 20
c = $2.5
substitute c = 2.5 into eq. 1
30 c + 50 r = $95
30 (2.5) + 50 r = 95
75 + 50 r = 95
50 r = 95 - 75
r = 20 / 50
r = 0.40
therefore, the individual costs of the compasses and rulers are:
compass = $ 2.50 each
ruler = $ 0.40 each

Answers
Answer:X=3
y= -4
Step-by-step explanation:
If we're solving for x or y, then the intercept we're not solving for is equal to zero. Solving for y means x=0, solving for x means y=0.
so solving for x, 4x=12--> x=3, since y=0 in this scenario.
Solving for y, x=0, so -3y=12--> y=(-4)
9514 1404 393
Answer:
see below for a table
Step-by-step explanation:
You can easily identify intercept points by solving for one variable when the other is zero.
x-intercept (y=0)
4x = 12
x = 12/4 = 3
y-intercept (x=0)
-3y = 12
y = 12/-3 = -4
So, the coordinate pairs of these points are ...
(3, 0) and (0, -4)
__
If you solve for y, you get ...
-3y = 12 -4x
y = (4/3)x -4 . . . . . divide by -3
This suggests that x being a multiple of 3 will be useful for finding integer values of y.
We already have points for x=0 and x=3. We can add points for x=6 and x=-3.
y = 4/3(6) -4 = 4
y = 4/3(-3) -4 = -8
So, the additional points are ...
(6, 4) and (-3, -8)
Sansra and bernice are starting a nutrition and exercise that will last 12 weeks. Sandra is starting at 150 pounds and plans to lose 1 pound a week. Bernice is starting at 135 and plans to lose 1/2 a pound a week. When during the program will sandra weight the same?
Answers
Answer:
They won't have the same weight during the program
Step-by-step explanation:
Let w = number of weeks
SANDRA:
Starting weight = 150 pounds
Weight lost per week = 1 pound
150 - w
BERNICE:
Starting weight = 135 pounds
Weight lost per week = 0.5 pound
135 - 0.5w
WEEK in which they'll weigh the same :
150 - w = 135 - 0.5w
150 - 135 = - 0.5w + w
15 = 0.5w
w = 15/ 0.5
w = 30
Since the program will last 12 weeks, they'll not have the same weight during the program

A store sells toys in bulk. It sells wooden blocks for $5 a pound and plastic bricks for $10
a pound. How many pounds of wooden blocks and plastic bricks should be used to make a
10-pound mixture that would sell for $80?
Answers
Answer:
4 pounds of wooden blocks and 6 pounds of plastic bricks should be used.
Step-by-step explanation:
Let w = wooden block
Let p = plastic bricks
Given the following data;
Price of wooden block per pounds = $5
Price of plastic brick per pounds = $10
*Translating the word problem into an algebraic equation*
For the 10-pound mixture;
[tex] w + p = 10[/tex] .........equation 1
For the $80 mixture;
[tex] 5w + 10p = 80[/tex] ..........equation 2
Solving the linear equation by using the substitution method;
Making w the subject in equation 1:
[tex] w = 10 - p[/tex] .......equation 3
Substituting "w" into equation 2;
[tex] 5(10 - p) + 10p = 80 [/tex]
Simplifying the equation, we have;
[tex] 50 - 5p + 10p = 80 [/tex]
[tex] 50 + 5p = 80 [/tex]
Rearranging the equation, we have;
[tex] 5p = 80 - 50[/tex]
[tex] 5p = 30 [/tex]
[tex] p = \frac {30}{5} [/tex]
p = 6 pounds (For the plastic brick).
To find w;
Substituting "p" into equation 3;
[tex] w = 10 - 6[/tex]
w = 4 pounds (For the wooden block).
2 p
In a nursery, there are 5 adults and 14 children. Write the ratio of adults to
children in the form 1:n
*
can someone help me?
Answers
Answer:
5:14
Step-by-step explanation:
The ratio of adults to children using the form 1:n would look like this:
number of adults : number of children
So:
5 adults : 14 children = 5:14
Answer:
1 : 2.8
Step-by-step explanation:
in such a case what the question is asking you to is to compare the numbers and simplify them with the left hand number.
ratio of adult to children
write it as 5:14
put the 1 :n underneath
5 : 14 what we want to find is the n. among the 2 sides one is complete
1 : n only whole numbers. to get n look at the complete side . if
5:1 14=14 x 1 /5(cross multiplication). or you can
divide both sides by the left hand number(5)
5 and 14 = 1 : 2.8
5 5
the n is what we were trying to find and compare it to 1
this means for every 1 adult there are 2.8 children

Answers
Answer:
A)
[tex]y=10.25x[/tex]
B)
24 hours
C)
$410
Step-by-step explanation:
We are given that Kelly’s paycheck varies directly with the number of hours she works.
We know that she received $133.25 for 13 hours of work.
Part A)
The standard form for the direct variation equation is:
[tex]y=kx[/tex]
Where k is the constant of variation.
Here, y is the paycheck amount and x is the number of hours Kelly worked.
We know that Kelly received $133.25 for 13 hours of work. Hence, y = 133.25 when x = 13:
[tex]133.25=13k[/tex]
Solve for k:
[tex]k=10.25\\[/tex]
Therefore, our constant of variation is 10.25.
We can substitute this into our equation:
[tex]y=10.25x[/tex]
Therefore, our direct variation equation is:
[tex]y=10.25x[/tex]
Contextually, the equation tells us that Kelly earns $10.25 per hour.
Part B)
Using the equation, we can determine the the number of hours Kelly worked to earn $246. We can substitute 246 for y:
[tex]246=10.25x[/tex]
Solve for x:
[tex]\displaystyle x=\frac{246}{10.25}=24[/tex]
Therefore, x = 24.
Therefore, Kelly must’ve worked 24 hours for her paycheck to be $246.
Part C)
We can use our equation. This time, we will substitute 40 for x and evaluate. Hence:
[tex]y=10.25(40)=\$410[/tex]
So, Kelly will earn $410 for working 40 hours.
What’s the answer for this? Only if you know tho!

A constant function is a
function of the form
= b . The slope of a constant function is
Answers
Answer:
The slope of the constant function is 0
Step-by-step explanation:
The equation of the constant function is f(x) = b, where b is the y-interceptThe constant function is represented graphically by a horizontal line, the y-coordinates of all points lie on it is bThe slope of any horizontal line is 0 because the difference between the y-coordinates of any two points on the line is 0, then m = 0, so its equation is y = b∵ The equation of the constant function is in the form f(x) = b
∵ The equation of the horizontal line is y = b
∴ f(x) = y
∵ The slope of the horizontal line is 0
∴ The slope of the constant function is 0
We want to get the slope of a constant function, we will see that the slope is equal to zero.
Linear functions:
A general linear function is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
For the case of the constant function we have:
y = b
Notice that we can rewrite this as:
y = 0*x + b
Then is easy to see that the slope of the constant function is equal to 0.

A shop sells pairs of trainers for £52 each. They make a percentage profit of 30% on each pair. What was the cost of each pair of trainers to the shop?i will mark as brainliest if right answer.
Answers
Answer:
£15.6
Step-by-step explanation:
Method 1:
You are trying to find 30% of £52.
Therefore:
[tex]\frac{30}{100} * 52 = \frac{30 * 52}{100}[/tex]
If you solve this you will find that 30 × 52 = 1560, and 1560 ÷ 100 = £15.6.
So, the answer is £15.6.
Method 2:
You can solve 30% of £52 by using an algebra equation.
By using the rule that to convert a percentage to a decimal you divide by 100, you can change 30% to be 0.3.
Now, in order to write the equation, you will have to include 0.3 and 52.
The equation is:
0.3 * 52 = x
Once you multiply, you will find that the answer is £15.6.

Explanation: If two angles form a linear pair, the angles are supplementary. A linear pair forms a straight angle which contains 180º, so you have 2 angles whose measures add to 180, which means they are supplementary. If two congruent angles form a linear pair, the angles are right angles.
