Answer:
Equation: 15 - f = n
Answer: n = 9
Step-by-step explanation:
The question is asking to write the equation. The equation would be
"15 - f = n" where f shirts folded
n = shirts remaining to fold
Then the question has gave us the value of f and has told us to solve it. Below is the solution.
15 - 6 = n
=> n = 9
Therefore, there is 9 shirts remaining after 6 of them are folded.
What did we solve?
We wrote our equation and solved what was required in the question.
I hoped this helped.
If possible... May I have brainliest :)
Answer: 2 1/2 1 1/6 2 2/5
Step-by-step explanation:
It will cost about $0.72 for three pair of shoes assuming shoe box is rectangular shape having 12 square inches of packing paper.
Step-by-step explanation:
- Assuming a shoe box rectangle in shape and the same size is required.
- Length of rectangle box assuming to be 4 inches.
- Width of rectangle box assuming to be 3 inches.
- as we know area of rectangle is Length * Breath(Width) .
- 12 square inches is the total packing paper required for each box.
- To cover cost of three pairs of shoes $0.02 per square inch.
- Each box would cost about 12 square inches * 0.02 pr square inches.
- 0.24 square inches of packing paper will be required.
- let three pairs of shoes be x
- Total pairs of shoes would be= (12 * 0.02)*x
- Answer would be for 3 pairs of shoes = 0.24*3 = 0.72 square inches.
Remark
Please number your pairs of equations going from left to right. The pair on the extreme left is (1) and the pair on the extreme right is (5).
(1)
If you multiply to top member of the pair by 2, you will get the bottom equation of the pair. What that tells you is that there are many (infinite) numbers of solutions.
(y = 3x + 4) * 2 remove the brackets.
2y = 6x + 8 Exactly the same equation as the bottom one = infinite solutions.
(2)
If the slopes are the same (both are -1) and the y intercepts are different (0,-2) and (0,-6) then the lines are parallel (they never meet) and have no solutions.
(3)
If the slopes are different, there is one solution. (9 and 1) There is one solution.
(4)
Four gives 1 solution as well at 0,0. That is because the slopes are different.
(5)
trick question. the slopes are quite different. one is 0 and the other is undefined. They meet at one point.(-6,-3). I solution.
