Answer: -3 13/40
Steps: (-⅛ + ⅖) - 3 ⅗
Convert mixed numbers to improper fractions: 3⅗ = 18/5
(-⅛ + ⅖) - 18/5
Remove the parentheses: -⅛ + ⅖ - 18/5
Find the common denominator which is 40.
So: -5/40 + 16/40 - 144/40
Since the denominators are equal, combine the fractions: -5 + 16 -144 divided by 40.
Add/ subtract the numbers: -5 + 16 - 144 = -133
= -133/40
Convert improper fractions to mixed numbers: 133/40 = 3 13/40
The answer is -3 13/40

Ms. Bailey is taking her children and their friends to the movies. She will pay $10 for her adult ticket and $6 for each child ticket. Ms. Bailey spends $46.00 at the movies. Write and solve an equation to determine the number of child tickets Ms. Bailey purchases.
Equation
10+6x=46
subtract both sides by 10
10-10 46-10
to get 6x=36
divide both sides by six to isolate the variable
6x/6 36/6
which gives you
x=6
6x + 10 = 46 is the equation to determine the number of child tickets Ms. Bailey purchases and Ms. Bailey purchases 6 child tickets.
Let's assume that Ms. Bailey purchases "x" child tickets.
The cost of each child ticket is $6, so the total cost of child tickets would be 6x dollars.
Ms. Bailey also purchases one adult ticket for $10.
The total cost spent by Ms. Bailey at the movies is $46. Therefore, we can write the equation:
6x + 10 = 46
To solve for "x," we can start by subtracting 10 from both sides of the equation:
6x = 46 - 10
6x = 36
Divide both sides of the equation by 6 to isolate "x":
x = 36/6
x = 6
Therefore, Ms. Bailey purchases 6 child tickets.

-3(2x - 1) + 8x = 15
Answer:
x = 6
Step-by-step explanation:
use distributive property to multiply the -3 with the numbers inside the parentheses
-6x + 3 + 8x = 15
combine like terms
2x + 3 = 15
subtract 3 from both sides
2x = 12
x = 6
Answer:
x=6
Step-by-step explanation:
Distribute -3 through the parentheses
Collect like terms
Move constant to the right hand side and change it sign
Subtract the numbers
Divide both sides by 2

A marathon is 26.2 miles long. There is a water station every 114 miles along the race route and at the finish line. How many water stations are needed for this marathon?
Answer: 21 water stations
Step-by-step explanation:
From the question, we are informed that a marathon is 26.2 miles long and that there is a water station every 1 1/4miles along the race route and at the finish line.
To get the number of water stations that are needed for this marathon, we divide 26.2 miles by 1 1/4miles. This will be:
= 26.2miles/1 1/4 miles
= 26.2 miles/1.25 miles
= 20.96
= 21 water stations

Answer:
The answer is c-0.52
Step-by-step explanation:

Answer:
(-6), -72
Step-by-step explanation:
-6 and -72 are negatives. The sign in parenthesis (-) shows the number is negative. -1 and any other number that has a negative sign will always be less than zero. 2 and 0.52 are positive numbers and they will always be bigger than zero. 0.52 can be tricky though. But always know that 0.1 and any other number is always bigger than 0.
