Answer:
27. My fiend solved the inequality correctly but graphed it incorrectly. The statement "x > 5" is correct but but since the symbol is "greater than" it should have been graphed with an open circle to the right rather than a closed circle to the right.
28. My friend is incorrect for both solving the inequality and graphing. The correct answer for solving the inequality would be "5 ≥ x ". And for graphing the correct answer would be closed circle to the right since the symbol is greater than.
Step-by-step explanation:
27. Solving the inequality
x - 7 > -2
+ 7 + 7
------- ------
0 5
answer: x > 5
Graphing the inequality
Since the symbol is greater than, it would be a open circle to the right because the the right of the number line is positives and the bigger numbers. It would be an open circle because unlike question 28 the symbol is just greater than, not greater than or equal to.
28. Solving the inequality
8 ≥ x + 3
-3 - 3
-------- --------
5 0
answer: 5 ≥ x
Graphing the inequality
Since the symbol is greater than than or equal to, it would be a closed circle to the right because the the right of the number line is positives and the bigger numbers. It would be an open circle because unlike question 27 the symbol is just greater than or equal to, not just greater than.
This might not be the right way to do it or the right answer for that matter, I am very new to solving and graphing inequalities so I just decided to give this one a shot.
Hope this helps ; )

Minh and Mikayla are selling wrapping paper for a school fund-raiser. Customers can
buy either packages of folded paper or rolls of paper. Minh sold 6 rolls of paper and 2
packages of folded paper for a total of $44. Mikayla sold 3 rolls of paper and 9 packages
of folded paper for a total of $54. How much does each roll cost? How much does each
package of folded paper cost?
Answers
Answer:
Let x=rolls of paper,y=folded paper:
6x+2y=44
3x+9y=54
-------
6x+2y=44
6x+18y=108
16y=108-44=64
y=4
x=6
Thus, a roll of paper cost $6,folded paper was $4 each

-8(1+4x)+7x=-25-8x
Answers
Answer:
x = 1
Step-by-step explanation:
-8(1+4x)+7x=-25-8x (Given)
-8 + -32x + 7x = -25 - 8x (Distribute)\
-8 + -25x = -25 - 8x (Combine like terms)
-17x = -17 (Move variables(x) to the left and constants to the right)
x = 1 (Divide) (the answer is positive because when you divide a negative number by a negative number it turns positive)

5/8-1/8=4/8, we know this because when subtracting fractions with the same denominator, you keep the denominators the same and subtract the numerators. 5-1=4. this gives you 4/8. now, we know 4 is half of 8, so this is equal to 1/2, but we also can divide both 4 and 8 by 4, giving us 1/2.
WILL MARK BRAINLIEST PLS HELP. Fill in the table by following the rules provided for each backpack.
Answers
Answer:
See complete answer
Step-by-step explanation:
Backpack 2 is 2x, 2y, so double each number:
(0,2) = (0, 4)
(8,2) = (16, 4)
(6,5) = (12, 10)
(2,5) = (4, 10)
(0,2) = (0,4)
Backpack 3 is x + 8, y - 2 so add 8 to x and subtract 2 from y:
(0,2) = (8, 0)
(8,2) = (16, 0)
(6,5) = (14, 3)
(2,5) = (10, 3)
(0,2) = (8, 0)
Backpack 4 is x, 2y, so keep the same x and multiply y * 2
(0,2) = (0, 4)
(8,2) = (8, 4)
(6,5) = (6, 10)
(2,5) = (2, 10)
(0,2) = (0,4)

A phone company advertises a new plan in which the customer pays a fixed amount of $ 25 per month for unlimited calls in the country and $ 0.10 per minute for international calls . If a customer paid 120 dollars , how many international minutes did they use ?
Answers
Answer: The answer would be 950 international minutes. Only if assuming that this is in one month since the question doesn't give much detail.
Step-by-step explanation:
X would be used to represent the number of months.
25+0.10x=120
0.10x=95
950 international minutes used
Answer:
950
Step-by-step explanation:
An equation to model this scenario would be: y = 0.1x + 25
y would mean the amount of money paid depending on x, which is the number of minutes.
In this problem, we know the amount of money. So we know y is 120.
We can then put 120 into the equation to find x.
120 = 0.1x +25
95 = 0.1x
x = 950
Therefore, x is 950.

11.50 + 1.15x = 12.65
11.50 - 11.50 + 1.15x = 12.65 - 11.50
➗ 1.15x = 1.15 ➗ what does x equal? Please explain in great detail how you figured this out also replace the = with the proper inequality sign and explain how you did that as well.
Answers
Answer: the answer is x= 1
Step-by-step explanation:
So we are dealing with 11.50 - 11.50 + 1.15x = 12.65 - 11.50
our first step is Simplify both sides of the equation so:
11.5 + -11.50 + 1.15x = 12.65 + -11.50 turns into:
(1.15x) + (11.5+ -11.5)= (12.65 + -11.5)
**we know 11.5 + -11.5 will cancel each other since they are opposite**
so it will be 1.15x= 1.15
now the very last step is to divide 1.15x on both sides which gives us 1
