Answer:
First situation
More than 3 hours
At least 10
15
75
Step-by-step explanation:
Let x be the number of hours
The equation will be
[tex]5x>15\\\Rightarrow x>\dfrac{15}{5}\\\Rightarrow x>3[/tex]
So, she needs to work more than 3 hours in order to make more than $15.
The situation that represents [tex]5x>15[/tex] is the first one.
Let x be the additional number of cans
The inequality will be
[tex]x+5\geq15\\\Rightarrow x\geq 15-5\\\Rightarrow x\geq 10[/tex]
So, the additional number of cans to be bought is at least 10.
Let x be the number of comic books Clarice has.
[tex]x>15[/tex]
So, Clarice needs to have more than 15 comic books.
Let x be age of Elizabeth
The equation will be
[tex]x=5\times 15\\\Rightarrow x=75[/tex]
So, Elizabeth is 75 years old.

According to the information the correct match would be: 3 1/2 - This is a rational number, but not an integer, 0.56 - This is a rational number, but not an integer, 5 - This is an integer, Square root of 11 - This is an irrational number, -3 1/2 - This is a rational number, but not an integer.
How to determine the type of number?To determine the type of number, we need to understand the properties of each number.
3 1/2 can be expressed as the fraction 7/2, which is a rational number (a number that can be expressed as a fraction), but not an integer (a whole number without a fractional or decimal part).
0.56 is a rational number as it can be expressed as the fraction 28/50, but it is not an integer as it has a decimal part.
5 is an integer because it is a whole number without any fractional or decimal part.
The square root of 11 is an irrational number since it cannot be expressed as a fraction or a terminating or repeating decimal.
-3 1/2 can be expressed as the fraction -7/2, which is a rational number (a number that can be expressed as a fraction), but it is not an integer (a whole number without a fractional or decimal part).

Help plsss I don’t get it
Answer:
y > 3x - 3
Step-by-step explanation:
First off, to write a linear equation or linear inequality, we use the slope-intercept form: y = mx + b, where m represents the slope of a line, and b represents the y-intercept.
The slope of the line is found using rise/run. The rise, in this case, is 3, and the run is 1. 3/1 is 3. So, we can replace the m in the equation with 3 to get:
y = 3x + b
To find b, simply look for where the line crosses the y-axis (vertical line). In this case, it's -3.
The equation you have now is y = 3x + (-3), which is y = 3x - 3.
You're not done yet. A dotted line like here means a point ON the line is not a solution to the equation, so you have to replace the = with < or >. In this case, the shaded region is everything GREATER THAN -3, meaning you use the > (greater than) symbol.
Your final answer is y > 3x - 3.
Hope this helped!

Step-by-step explanation:
The other answer should get the Brainliest. Don't neglect awarding it. They are very good to get.
I'm only going to add a graph for you to see. All it does is point out what < and > mean.
As the other responder said, when the boundary is dotted, it is not included in the shaded part.
Also he pointed the difference between < and >. That is what I wanted to address. It is easy to tell.
< is less than the boundary and it is blue.
> is greater than, and it is green.
if the line is solid, then ≤ or ≥ is used.
Solve for c.
2(c +1) = 10
Answer:
c = 4
Step-by-step explanation:
[tex]2(c+1) = 10[/tex]
Lets divide both the sides by 2.
[tex]=> \frac{2 (c+1)}{2} = \frac{10}{2}[/tex]
[tex]=> c + 1 = 5[/tex]
Now , lets substract 1 on both the sides.
[tex]=> c + 1 - 1 = 5 - 1[/tex]
[tex]=> c = 4[/tex]
The solution to the equation 2(c + 1) = 10 is c = 4.
We have,
To solve for c in equation 2(c + 1) = 10, we will apply the distributive property and simplify the equation step by step.
Let's solve it:
Distribute the 2 to the terms inside the parentheses:
2c + 2 = 10
Move the constant term (2) to the right side by subtracting 2 from both sides of the equation:
2c + 2 - 2 = 10 - 2
Simplifying further:
2c = 8
Divide both sides of the equation by 2 to solve for c:
(2c) / 2 = 8 / 2
Simplifying further:
c = 4
Therefore,
The solution to the equation 2(c + 1) = 10 is c = 4.

Miya flips a coin and rolls a 6-sided number cube labled 1-6 and records tge outcome. About how many times is she likely to flip heads and roll a 3 out of 48 trials
Answer:
4 times
Step-by-step explanation:
Sample space :
6 sided cube = (1, 2, 3, 4, 5, 6)
Coin = (H, T)
Probability = required outcome / Total possible outcomes
Probability of head (H) = P(H) = 1 /2 = 0.5
Probability of 3 = P(3) = 1 /6 = 0.166666
Probability of heads and 3 on a single try = p(H) * p(3) = 0.5 * 0.166666 = 0.083333
Hence, expected number of times this is likely to occur in 48 tries :
0.083333 * 48 = 4
Four times a number plus five times the number is the same as ten more than eight
times the number. Find the number
Answer:
The number is 10.
Step-by-step explanation:
Given that:
Four times a number plus five times the number is the same as ten more than eight times the number.
Let,
x represent the number.
According to given statement,
4 times the number + 5 times the number = 10 + eight times the number
4x+5x=10+8x
Solving the equation,
9x=10+8x
Subtracting 8x from both sides
9x-8x=10+8x-8x
x=10
Hence,
The number is 10.

This equation shows how the total amount of paper Scott's office has recycled depends on the number of weeks since they started the new recycling plan. p = 12w The variable w represents the number of weeks the office has been on the new recycling plan, and the variable p represents the total kilograms of paper recycled. How many weeks will it take Scott's office to recycle a total of 12 kilograms of paper?
Answer:
1 week
Step-by-step explanation:
Given:
p = 12w
Where,
w = number of weeks the office has been on the new recycling plan
p = total kilograms of paper recycled.
How many weeks will it take Scott's office to recycle a total of 12 kilograms of paper?
Find w when p = 12
p = 12w
12 = 12w
Divide both sides by 12
w = 12/12
= 1
w = 1 week
Mariana plans to visit an amusement park where she must pay for admission and purchase tickets to go on the rides. Mariana wants to find the total cost for a day at the amusement park. She wrote the equation c = 1.50x + 12 to predict c, the total cost for a day at the amusement park. What could the number 12 represent in Mariana's equation?
Answer: The number 12 represents admission charge in Mariana's equation.
Step-by-step explanation:
As per given ,
Total cost = ( Charge per ticket) (Number of tickets) + (Admission fees) (i)
For x = Number of tickets, the total cost (c) for a day at the amusement park is given as
[tex]c = 1.50x + 12[/tex] (ii)
Here, 12 = Admission fees [Comparing (i) and (ii)]
Hence, the number 12 represents admission charge in Mariana's equation.

What is the difference between the let statements of consecutive even integers and consecutive odd integers
Answer and Step-by-step explanation:
The word, "Consecutive" means, "Back-to-back" or "One after the other." Therefore, consider these integers:
1, 2, 3, 4, 5, 6, 7, 8, . . .
If we write down these integers in such a way that only even integers follow back-to-back, we have:
2, 4, 6, 8, . . .
If we write down these integers in such a way that only odd integers follow back-to-back, we have:
1, 3, 5, 7, . . .
Since 2, 4, 6, 8, . . . Are all even integers that follow back-to-back, then this is known of consecutive even integers.
Since 1, 3, 5, 7, . . . Are all odd integers that follow back-to-back, then this is known of consecutive odd integers.
