Puzzles are packaged in groups of 3. If the store has 183 nature puzzles and 165 animal puzzles, how many packages of puzzles are there?
Answers
Answer: 116 packages
Step-by-step explanation:
From the question, we are informed that Puzzles are packaged in groups of 3 and that the store has 183 nature puzzles. The number of packages here will be:
= 183/3
= 61 packages
For the 165 animal puzzles, the number of packages will be:
= 165/3
= 55 packages
The total number of packages of puzzles will be:
= 61 + 55 packages
= 116 packages
Answer:
116
Step-by-step explanation:
First find total number of puzzles.
183+165=348
Then divide the total puzzles by puzzles in a package (3)
348÷3=

peter has 6/7 of a stack of baseball cards left. If he is planning on splitting what he has left into stacks that are each 3/28 of a pack of cards, how man stacks can he make?
Answers
=======================================================
Work Shown:
Let's say there are 28 cards in a full stack.
6/7 = 24/28 after multiplying top and bottom by 4
Since he has 24/28 of a stack left, this means he has 24 cards left.
He wants to arrange the remaining cards into piles so that each pile consists of 3/28 of a full stack. In other words, he wants each pile to have 3 cards.
So this must mean he will get 24/3 = 8 piles
(8 piles)*(3 cards per pile) = 8*3 = 24 cards total
A fraction is a way to describe a part of a whole. The number of stacks that Peter has left into stacks that are each 3/28 of a pack of the left cards is 8.
What is a Fraction?A fraction is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25.
Given that Peter has 6/7 of a stack of baseball cards left. Also, he makes small stacks from the left cards of size 3/28. Therefore, the number of stacks Peter made,
[tex]\text{Number of stacks Peter made} = \dfrac{\text{Stack of baseball cards left}}{\text{Size of small stack of cards}}\\\\\\\text{Number of stacks Peter made} = \dfrac{\frac{6}{7}}{\frac{3}{28}}\\\\\\\text{Number of stacks Peter made} = \dfrac{6 \times 28}{7 \times 3} = 8[/tex]
Hence, the number of stacks that Peter has left into stacks that are each 3/28 of a pack of the left cards is 8.

A rectangular price tag has a cemeter of 30 centimeters, It's area is 54 square centimeters
What are the dimensions of the price tag
Answers
Answer:
l = 9 inches and b = 6 inches.
Step-by-step explanation:
Given that,
The perimeter of a rectangular price tag, P = 30 cm
The area of rectangular price tag, A = 54
We need to find the dimensions of the price tag.
The area of rectangle is given by :
A = lb
So,
54=lb ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
So,
30=2(l+b)
15=(l+b) ...(2)
We need to solve equation (1) and (2) such that,
l = 9 inches and b = 6 inches.

A total of 328 tickets were sold for the school play. They were either adult tickets or student tickets. The number of student tickets sold was three times the
number of adult tickets sold. How many adult tickets were sold?
Answers
Answer:
246 adult tickets were sold
Step-by-step explanation:
System of equations:
Variables:
x = number of adult tickets sold
y = number of student tickets sold
There were a total of 328 tickets sold, thus:
x + y = 328
The number of student tickets sold was three times the number of adult tickets sold, thus:
y = 3x
Substituting in the first equation:
x + 3x = 328
Simplifying:
4x = 328
Dividing by 4:
x = 328/4
x = 82
y = 3*82= 246

A college student completed some courses worth 3 credits and some courses worth 4 credits. The studentearned a total of 59 credits after completing 18 courses.How many courses worth 3 credits did the student complete?
Answers
Answer:
The student completed 13 courses worth 3 credits
Step-by-step explanation:
System of Equations
Let's assign the following variables:
x = number of courses worth 3 credits
y = number of courses worth 4 credits
Some student completed 18 courses thus:
x + y = 18 [1]
The student earned a total of 59 credits:
3x + 4y = 59 [2]
From [1]:
y = 18 - x
Substituting in [2]:
3x + 4(18 - x) = 59
Operating:
3x + 72 - 4x = 59
Simplifying:
-x = 59 - 72 = -13
x = 13
The student completed 13 courses worth 3 credits

Answer:
x = 10°, y = 20°
Step-by-step explanation:
Fill in the missing angle measures, 20° and 70°.
7x = 180 - 90 - 20
7x = 70
x = 10
2y = 180 - 7x - 5x - 20 = 40
y = 20
Y=20
Explanation-you would take 20+90 then subtract that from 180 which gives you 70 and 7x10 is equal to 70. 70+110=180. If x=10 then 5x would give you 50, then you add 20 and get 70. Then you add another 70 because the angle between the green line and black line is equal to 7x. This would give you 140. So 2y would have to be 2(20) which give you the remaining 40.

Two chemical plants, one at Macon and one at Jonestown, produce two types of fertilizer, low phosphorus (LP) and high phosphorus (HP). At each plant, the fertilizer is produced in a single production run, so the two types are produced in fixed proportions. The Macon plant produces 1 ton of LP and 3 tons of HP in a single operation, and it charges $600 for what is produced in one operation, whereas one operation of the Jonestown plant produces 1 ton of LP and 1 ton of HP, and it charges $1,000 for what it produces in one operation. If a customer needs at least 100 tons of LP and 180 tons of HP, how many production runs from each plant should be ordered to minimize the cost.

33 - 9x + 48 = 180
81 - 9x = 180
- 9x = 99
