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.

Line m has the equation y= 2/3 (x) - 3 . Line n has the points given in the table to the right. Holly says the two lines have the same slope. Is Holly correct?
A. Yes, they both have a slope of .
B. Yes, they both have a slope of -3.
C. No, the slope of line m is and the slope of line n is .
D. No, the slope of line m is -3 and the slope of line n is .
Answer: A) Yes, they both have a slope of 2/3
=============================================================
Explanation:
The equation y = (2/3)x - 3 has slope 2/3 since it is the coefficient of x
The coefficient is the number to the left of the variable.
-------------------------------------
Now let's pull two points from the table.
Pick any two points you want. I'll pick the last two rows to get the two points (4,2) and (13,8)
Subtract the y values to get 8-2 = 6
Subtract the x values in the same order: 13-4 = 9
Divide the differences:
slope = rise/run
slope = (change in y)/(change in x)
slope = 6/9
slope = 2/3
We get the same slope as before. Holly is correct.
What is the slope of a line perpendicular to the line whose equation is

Fun, which looks promising. Here's what you learn when you call Jump and Fun:
There is a flat fee of $120 to rent a room. There is an additional charge of $5 per
child for access to the bounce houses and miniature golf course. The more
friends your sister invites, the more the party will cost.
Write an equation to express what the cost will be for the party. Use x for the
number of kids that will attend.
Your answer
Answer:
Y=x(5)+120
Step-by-step explanation:
Y= the money you have to pay for the party
X(5)= you multiply x by 5
+120= you add the fee

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.

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
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.
4 Write the equation of a line in slope-intercept form that has a slope of -2 and passes through the point (-1,8
Answer:
y = -2x + 6
Step-by-step explanation:
Slope-intercept form: y = mx + b
Given:
Slope(m): -2
Point: (-1, 8)
To write the equation in slope-intercept form we need to find the slope(m) and the y-intercept(b).
Since we already know the slope is -2, we can move on to finding the y-intercept. To find the y-intercept, input the values of the slope and the point into the equation format and solve for b:
y = mx + b
8 = -2(-1) + b
8 = 2 + b
6 = b
The y-intercept is 6.
Now that we know the slope and the y-intercept, we can write the equation:
y = -2x + 6

Answer: [tex]g = 6\sqrt{6} \ \ \text{yards}[/tex]
=============================================
Explanation:
When dealing with a 30-60-90 triangle, the short leg x and the long leg y can be tied together using this formula
[tex]y = x*\sqrt{3}[/tex]
We see that the long leg is exactly [tex]\sqrt{3}[/tex] times longer than the short leg.
Therefore we can say,
[tex]y = x*\sqrt{3}\\\\y = 6\sqrt{2}*\sqrt{3}\\\\y = 6\sqrt{2*3}\\\\y = 6\sqrt{6}\\\\g = 6\sqrt{6}\\\\[/tex]
