The linear equation where y is the price of the number of markers x is as follows:
y = 1 / 2 x + 2Let
the price of each marker = y
Therefore,
The price of a box with 10 markers = $7
The price of a box with 24 markers = $14
(10, 7)(24, 14)
Using linear equation
Slope intercept formy = mx + bwhere
m = slope
b = y-intercept
Therefore,
m = 14 - 7 / 24 - 10
m = 7 / 14
m = 1 / 2
Therefore, let's find b
7 = 1 / 2(10) + b
7 - 5 = b
b = 2
Therefore, the linear equation where y is the price of the number of markers x is as follows:

Answer:
y = 1/2x+2
Step-by-step explanation:
We have two points ( 10,7) and (24,14)
We need to determine the slope using the slope formula
m = ( y2-y1)/(x2-x1)
= ( 14-7)/(24-10)
= 7/14
= 1/2
The slope is 1/2
The slope formula is y=mx+b where m is the slope and b is the y intecept
y = 1/2x+b
Using one of the points
7 = 1/2 (10)+b
7 = 5+b
7 -5 =b
2=b
y = 1/2x+2

Solve the following equation:
2/3 - 1/x = 13/15
Answer:
x=−5
Step-by-step explanation:
Steps:
Step 1 to 4 : Simplify
Steps 5: Calculating the Least Common Multiple
Steps 6: Calculating Multipliers
The correct answer for this question is x=−5
Answer: x=−5
Hope this helps.
Answer:
x = -5
Step-by-step explanation:
2/3 - 1/x = 13/15
Subtract 2/3 from each side
2/3 -2/3 - 1/x = 13/15 -2/3
-1/x = 13/15 - 2/3
Getting a common denominator
-1/x = 13/15 -2/3*5/5
-1/x = 13/15 - 10/15
-1/x = 3/15
Using cross products
3x = -15
Divide each side by 3
3x/3 = -15/3
x = -5
A 13-foot board is cut into two pieces. The length of the shorter piece is 1 ft more than half the length of the longer piece. Find the length (in ft) of the shorter piece.
Answer: 1
Step-by-step explanation: 1
Length of the shorter piece of board is equals to 5foot.
What is length?
" Length is defined as the distance between two end points of any object."
According to the question,
Length of the board = 13foot
'l' represents the length of the longer piece
As per the condition given we have,
Length of the shorter piece = [tex]\frac{l}{2} +1[/tex]
Therefore,
[tex]l + \frac{l}{2}+1=13[/tex]
⇒ [tex]\frac{3l}{2} =13-1[/tex]
⇒[tex]l= \frac{2}{3} (12)[/tex]
⇒ [tex]l= 8foot[/tex]
Length of the shorter piece = [tex]\frac{8}{2} +1[/tex]
= [tex]5foot[/tex]
Hence, length of the shorter piece of board is equals to 5foot.

Step-by-step explanation:
students in the group i would get 30 by adding all the frequency column together
the mean is 40/5 which is 8
the range of marks is the difference between the smallest number and the greatest number in the set so the difference of 6 and 10 which is 4
Answer:
Ans no.1) 4
Ans.no.2) 30
Ans.no3) 8
Step-by-step explanation:
no.1) to find a range we have to do subtract from the highest mark and the smallest mark
no.2) to find the total student you have to add up the frequency
no.3) to find the range first add up all the mark and count the total no. ( 5 ) then divide it by the sum of the no. and the count of no.

Please see the attachment below.
I hope this helps!
Answer:
4. 121800
5. 591.09375
6. 0.25
Step-by-step explanation:
4. It's an AP with:
first term(a): 12
common difference(d): 24-18 = 6
Sn = (n/2)(2a + (n-1)d)
S200 = (200/2)[2(12) + (200-1)(6)]
= 121800
5. It's an GP with:
first term(a): 12
common ratio(r): 18/12 = 1.5
Sn= a(r^n -1)/(r-1)
S8 = 12(1.5⁸-1)/(1.5-1)
= 18925/32 = 591.09375
6. It's an infinite GP with:
first term(a) = 1/12
common ratio: 1/18 ÷ 1/12 = ⅔
Sinfinity: a/(1-r)
= (1/12) ÷ [1-⅔]
= 1/12 ÷ 1/3
= 1/12 × 3
= 1/4 = 0.25

The Happy-Go-Lucky Beach was 163 feet long from parking lot to high tide. After last year's hurricane came ashore, the beach only measured 154 feet
long. What was the percent of change?
About 94.5% of increase
About 94.5 % of decrease
About 5.5% increase
About 5.5% decrease
Answer:
About 5.5% decrease
Step-by-step explanation:
Here, we want to calculate the percentage increase or decrease and its value.
The first thing to do here is to check if we are going to have a decrease or an increase.
since the value before the change is higher than the value after the change, then what we have is a decrease.
Mathematically, the percentage decrease is calculated as follows;
% decrease = (old value - new value)/old value * 100%
old value = 163 feet
new value = 154 feet
% decrease = (154-163)/163 * 100%
% decrease = -9/163 * 100%
% decrease = -5.52%
Thus the best answer is about 5.5% decrease

find the coordinate of K' after a Glide reflection of the triangle: translation 4 units up and 4 units right then a reflection across the line y = 1.
Part 3a
Answer:
a. (-1, 3)
Step-by-step explanation:
The "glide" 4 units right and up is the transformation ...
(x, y) ⇒ (x+4, y+4)
The reflection across y=1 is the transformation ...
(x, y) ⇒ (x, 2-y)
Combined, you have the transformation ...
(x, y) ⇒ (x +4, 2-(y +4)) = (x +4, -2-y)
Then, ...
K(-5, -5) ⇒ K'(-5 +4, -2-(-5)) = K'(-1, 3)

G/2 + 7 = 21
Can I get help with this??
Answer:
g = 28
Step-by-step explanation:
g/2 + 7 = 21
Subtract 7 on both sides.
g/2 = 21-7
g/2 = 14
Multiply 2 on both sides.
g = 2(14)
g = 28
Answer:
g=28Solution,
[tex] \frac{g}{2} + 7 = 21 \\ or \: \frac{g + 7 \times 2}{2} = 21 \\ or \: \frac{g + 14}{2} = 21 \\ or \: g + 14 = 42(cross \: multiplication) \\ or \: g = 42 - 14 \\ g = 28[/tex]

Find the volume of the pyramid. 100 points
120 yd^3
Step-by-step explanation:
The formula for the volume of a pyramid is...
[tex]V=\frac{1}{3}Bh[/tex]
B is the area of the base and h is the height from the middle of the pyramid to the top. Since we know both of these we can plug them in.
[tex]V=\frac{1}{3}(45*8)[/tex]
[tex]V=\frac{1}{3}*360[/tex]
[tex]V=[/tex]
120
The volume for the pyramid is 120 yd^3.
Answer:
120 yards ^3
Step-by-step explanation:
To solve we need to know the formula.
The formula for the volume of a pyramid is 1/3 B * H
B= 45 and H = 8. We can sub those values in to the formula to solve.
= 1/3 45*8
= 1/3 360
=120
Since we multiplied yd^2 by yd, we get yd^3
So the answer is 120 yd^3

Samantha and Jillian were going for a walk. Jillian left 15 seconds ahead of Samantha. • Samantha walked at a speed of 7 feet per second. • Jillian walked at a speed of 6 feet per second. How many seconds had Jillian been walking when the two girls had walked the same distance?
Is the answer 105?
Answer:
105 seconds
Step-by-step explanation:
To solve this, we can set up an equation.
First, let's find how far ahead Jillian is.
15*6=90
Jillian is 90 feet ahead.
Let's name the time that Samantha walks x.
7x is the distance Samantha walks.
90+6x is the distance Jillian walks.
We want to find how many seconds they have walked when the distance is equal.
So let's form an equation.
7x=90+6x
Subtract 6x from both sides.
x=90
Samantha needs to walk 90 seconds.
Jillian started 15 seconds before that.
90+15=105
Jillian had been walking for 105 seconds when the two girls had walked the same distance.

Answer:
P=96;A=540
Step-by-step explanation:
To find the perimeter, the distance around the pool, all you need to do is add 18+18 then add 30+30. Why? Because assuming the pool is a rectangle, it would have 4 sides. The two width sizes as 18 and the two lengths as 30. Now, finding the area is even simpler. All you have to do is multiply the width by the length. 18*30.
