Laura left Dunkin Donuts at 1 PM traveling 30 mph. Two hours later her friend Jen left the same Dunkin Donuts and started after her on the same route traveling 45 mph. At what time will Jen catch up to Laura?
Answer:
It took Jen 4 hours to catch up with Laura
Step-by-step explanation:
Gaining speed 45-30= 15 mph
Laura's head start 30×2=60 miles
Time for Jen to catch up 60÷15= 4 hours
In other words
30(t+2)= 45t
30t+60= 45t
60=45t-30t
60= 15t
t=4 hours

Raul earns $37.50 for 3 hours of babysitting. He earns the same amount
per hour each time he babysits. How many hours does Raul have to babysit to earn $100
9 hours
Step-by-step explanation:
cuz that's the answer
Raul would have to babysit for 8 hours to earn $100.
What is the division operation?In mathematics, divides left-hand operands into right-hand operands in the division operation.
To determine the number of hours Raul has to babysit to earn $100, you need to divide the amount he wants to earn ($100) by the amount he earns per hour.
The amount of Raul earns per hour by dividing the total amount he earned by the number of hours he worked.
As per the question, Raul earned $37.50 for 3 hours of babysitting,
So, he earned $37.50 / 3 hours = $12.50 per hour.
This means that to earn $100, he would have to work:
⇒ $100 / $12.50 = 8 hours.
Therefore, he would have to babysit for 8 hours to earn $100.

Answer:
Here are ten numbers:
3 7 2 4 7 5 7 1 8 8
a)
Write down the mode. 7
b)
Work out the median.
c)
Calculate the mean. add all and divide by 10
d)
What is the range? 7
Answer:
Mode: 7
Median: 6
Mean: 5.2
Range: 5
Step-by-step explanation:
For the mode you have to find which number is present the most times
For the median you have to find the middle number if the total sum of numbers is an odd number, and find the average of the two if it is an even number ,like i did here (7+5)/2=6
For the mean you have to add every number and then devide with the total number of the numbers given:
(3+7+2+4+7+5+7+1+8+8)/10=5.2
For the range you have to find the largest number and subtract the smallest number from it (8-3)=5

The following table shows the total number of quizzes taken in high school. How many quizzes are taken per week?
Answer:
4
Step-by-step explanation:
y÷x
12÷3=4 and 20÷5=4
4 quizzes are taken per week.
A linear equation is given by:
y = mx + b;
where y, x are variables, m is the rate of change and b is the y intercept.
Let y represent the total number of quizzes after x weeks.
From the table we can see that when y = 12, x = 3 and when y = 20, x = 5. Hence:
Number of quizzes per week = 12/3 = 20/5 = 4
Hence, 4 quizzes are taken per week.

describe a system of linear equations that has no solution?
Answer:
If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line. If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.
Step-by-step explanation:
Hope this helps - Good luck ^w
we can conclude that the system of linear equations has no solution when the graphs of equations are parallel.
What is a linear system of equations?A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.
The collection of one or more linear equations, such that each of those equations have same set of variables, are known as system of linear variables.
If a consistent system has an infinite number of solutions, it is dependent. When we graph the equations, both equations represent the same line.If a system has no solution, it is said to be inconsistent . The graphs of the lines do not intersect, so the graphs are parallel and there is no solution.Therefore, we can conclude that the system of linear equations has no solution when the graphs of equations are parallel.

Which of the following best describes the solution to the equation below? 3(x+ 7) = 3x + 21
Answer:
x = x; the solution has infinite solutions
Step-by-step explanation:
3(x+ 7) = 3x + 21; distribute the 3 on the left side
3x + 21 = 3x + 21; now subtract 21 from both sides
3x = 3x; divide by 3
x = x; the solution has infinite solutions. Since both terms are equal any value for x will be true on this equation.
