1. Mr. Hudson bought some shirts for the new members of his band. The cost for the number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. Write an equation to represent the scenario. Use x as your variable. 2 Mr. Hudson bought some shirts for the new members of his band. The cost for the number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. How many shirts were purchased?
Answer:
6x + 4 - 1/100 = 77.5
Step-by-step explanation:
Inc shipping all shirts 77.49
Shirt individual cost = 12.25
We find the division first = 77.49-3.99 = 73.5 = 73 1/2
Then we divide 73.5 / 12.25 = 6
Then we have our equation
6x + 4 - 1/100 = 77.5
The perimeter of an airplane ticket is 30 centimeters. The area is 50 square centimeters. What are the dimensions of the ticket?
Answer:
The length can be 5 and the width 10.
Step-by-step explanation:
perimeter is equal to 2L + 2W
area is equal to L * W
you get 2 equations:
30 = 2L + 2W
50 = L*W
we'll solve by substitution.
you can use either equation to solve for either variable.
we'll use the second equation to solve for L.
second equation is:
50 = L*W
divide both sides of this equation by W to get:
L = 50/W
we now have a value of L that we can substitute in the first equation which we can then use to solve for W.
the first equation is:
30 = 2L + 2W
replace L with 50/W to get:
30 = 2*(50/W) + 2W
simplify to get:
30 = 100/W + 2W
multiply both sides of this equation by W to get:
30W = 100 + 2W^2
subtract 30W from both sides of this equation to get:
2W^2 - 30W + 100 = 0
factor this equation to get:
(2W - 20) * (W - 5) = 0
solve for W to get:
W = 10 or W = 5
if W = 10, then use the equation of 50 = L*W to get L = 5
if W = 5, then use the equation of 50 = L*W to get L = 10
you have 2 possible solutions.
L = 5 and W = 10 or:
L = 10 and W = 5
both are plausible so we'll test them both out.
when L = 5 and W = 10:
the first equation becomes 2*5 + 2*10 = 10 + 20 = 30
the second equation becomes 5*10 = 50
both equations confirm that the solution of L = 5 and W = 10 is good.
when L = 10 andW = 5:
the first equation becomes 2*10 + 2*5 = 20 + 10 = 30
the second equation becomes 10*5 = 5
both equations confirm that the solution of L = 10 and W = 5 is good.
the ticket can have either:
a length of 5 and a width of 10 or:
a length of 10 and a width of 5.
since the length is usually longer than the width, you are free to choose that the ticket most likely has a length of 10 and a width of 5.
alternatively, you can simply say that the dimensions are 5 by 10 and let the recipient of that information determine which is the length and which is the width.
mathematically, the length can be 10 and the width 5 or the length can be 5 and the width 10.

You can split apart the shape into to two different rectangles. The first one would have dimensions 3yd by 5 yd. The second one would have 2 yd by 4 yd. So your area is (3 * 5) + (2 * 4) = 15 + 8 = 23 yards
What is the solution to this system?
Answer: There is no solution
Step-by-step explanation:
The system of a systems of equations on a graph is the coordinate where the 2 lines intersect, or come together. In this picture, the 2 lines don't intersect at a point, so there is no solution. Here are some rules for systems of equations on a graph:
How to know if it has 'infinite' solutions: If it has infinite solutions, the 2 lines share the same points. In other words, they are basically just on top of each other, or in the exact same spot.
How to know if there are 'no solutions': The 2 lines never come together (intersect). This is true in this graph because they are always apart.
How to know if there is 'one solutioin': The 2 lines cross each other, come together, or intersect (all the same meaning), at 1 point .
Hope this helps :)) Also brainliest would be appreciated :D

Lily and Mackenzie collected some stamps. If Lily gave 4 stamps to Mackenzie, Mackenzie would have twice as many stamps as Lily. If Mackenzie gave 4 stamps to Lily, they would have the same number of stamps. How many stamps did each girl have?
GIVING BRAINLIEST. PLS HELP. SHOW UR WORK TOO
Answer: hope this helps ♡
Lily had 16 stamps and Mackenzie had 20 stamps.
Step-by-step explanation:
Lily gives 4 stamps to Mackenzie
(Mackenzie) m + 4 = 2(L - 4) (Lily)
Solve for Lily:
m + 4 = 2L - 8
m + 4 + 8 = 2L
(m + 12) ÷ 2 = 2L ÷ 2
(m + 12) ÷ 2 = L
L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)
Mackenzie gives 4 stamps to Lily
(Mackenzie) m - 4 = L + 4 (Lily)
m - 4 = ((m + 12) ÷ 2) + 4
m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4
2m - 4 + 4 = (m + 12) + 4 + 4
2m - m = (m - m + 12) + 8
m = 12 + 8
m = 20 (we will substitute this value of m in the next equation)
L = (m + 12) ÷ 2
L = (20 + 12) ÷ 2
L = 32 ÷ 2
L = 16

Which one of the numbers does not belong in the following series?
2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281
A-FIVE
B-SEVEN
C-FOURTEEN
D-FORTY-ONE
E-ONE HUNDRED TWENTY-TWO
Answer:
i think 7
Step-by-step explanation:
Option B: SEVEN
The number that goes not belong in the following series is SEVEN
Given :
The numbers in the series is
2 - 5 - 7 - 14 - 41 - 122 - 365 - 1094 - 3281
First number is 2
[tex]2 \cdot 3 -1=5\\[/tex]
Lets multiply the previous term by 3 and subtract 1 to check the other terms
[tex]5 \cdot 3 -1= 14\\14 \cdot 3 -1= 41\\41 \cdot 3 -1= 122\\122 \cdot 3 -1= 365\\365 \cdot 3 -1= 1094\\1094 \cdot 3 -1= 3281\\[/tex]
From the series we can see that 7 does not belong to the series .
So, SEVEN does not belong to the series .
