Solve it considering correct order of operations:
9 - 3 ÷ 1/3 + 1 = Division first9 - 3 × 3 + 1 = Multiplication first9 - 9 + 1 = Subtraction is same priority with addition 0 + 1 = Addition1 AnswerAnswer:
9 - 3 ÷ (1/3) + 1 = 1
Step-by-step explanation:
Given problem,
→ 9 - 3 ÷ (1/3) + 1
Let's solve the problem,
→ 9 - 3 ÷ (1/3) + 1
→ 9 - (3 × 3) + 1
→ 9 - 9 + 1
→ 9 - 8 = 1
Thus, the answer is 1.
Flagship Cinemas sells movie tickets that are $4 for matinees and $7 for regular shows. One night the theater sells 578 tickets and collects $3365 in total ticket sales. Whích system best represents the situation?
Answer:
4x + 7y = 3365
x + y = 578
x = matinees
y = regular
Step-by-step explanation:
Given
$4 = matinees
$7 = regular
Total tickets = 578
Money collected = $3365
If one calls the amount of matinees that when "x" and the amount of regulars that went "y", then one can form the system;
4x + 7y = 3365
x + y = 578
Solving the system;
Multiply the second equation by (-4)
4x + 7y = 3365
-4x - 4y = -2312
Add the equations
4x + 7y = 3365
-4x -4y = -2312
3y = 1053
Inverse operations
3y = 1053

Rachel has a ribbon that is 16.2 metres long. Sheena has a ribbon that is 8.3 metres shorter than Rachel's ribbon.What is the total length of the two ribbons?
Answer:
24.1m
Step-by-step explanation:
We have these informations to answer this question with.
Length of Rachel's ribbon = 16.2 m
Sheena's ribbon = 8.3m shorter than Rachael's
So,
Sheena's ribbon = length of Rachael's ribbon - 8.3m
= 16.2m - 8.3m
= 7.9m
The total length of the two ribbons
= length of Sheena's ribbon + length Rachael's ribbon
= 16.2 + 7.9
= 24.1 m

Daniel and Lisa are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of holiday wrapping paper. Daniel sold 5 rolls of plain wrapping paper and 3 rolls of holiday wrapping paper for a total of $74. Lisa sold 1 roll of plain wrapping paper and 3 rolls of holiday wrapping paper for a total of $58. Find the cost each of one roll of plain wrapping paper and one roll of holiday wrapping paper
Answer:
P = 4 & H = 18
Step-by-step explanation:
Daniel : 5 plain paper + 3 holiday paper = 74, 5P + 3H = 74 . Lisa : 1 plain paper + 3 holiday paper = 58, P + 3H = 58 . Solving two equations, P = 4 & H = 18

rewrite in simplest form (-4x+6y-)-(-9x-8y
Answer:
5x + 14y
Explanation:
−4x+6y−(−9x−8y)
Distribute the Negative Sign:
= −4x+6y+−1(−9x−8y)
= −4x+6y+−1(−9x)+−1(−8y)
= −4x+6y+9x+8y
Combine Like Terms:
= −4x+6y+9x+8y
= (−4x+9x)+(6y+8y)
= 5x + 14y
