A school group has $140 to spend. Write and solve an inequality that represents the cost to rent the main hall, where h represents the number of hours the group can rent the room.
Answer:
a. 15h + 40 ≤ 140
b. h ≤ 6.6
Note: The question is missing a table. The table is shown in the attachment below.
Step-by-step explanation:
a. The school group has $140 to spend, and so can only spend an amount less than or equal to $140 when renting the main hall.
The cost of renting the main includes an hourly rate of $15 and a set-up fee of $40.
Let h represent the number of hours the group can rent the hall.
Cost of renting the main hall, C is given by:
15h + 40 ≤ 140
b. Solution of the inequality:
15h + 40 ≤ 140
15h ≤ 140 - 40
15h ≤ 100
h ≤ 100/15
h ≤ 6.6
Therefore, the main hall can only be rented for a maximum of 6.6 hours or less

explain why 3(5x) does not equal to (3 times 5)(3times x)
Answer:
Because 3(5x) is the same as 3 *5 * x
Step-by-step explanation:
When a number is next to another in parantheses, it signifies multiplication. In this case, we already have 5 and x grouped together by a multiplication sign, so the entire thing is 5 * x. The statement below is key
Distribution in multiplication is only possible if a variable is grouped to another real number by a plus or minus sign.
So in this case, we have 3 * 5 * x, which is 15x. However, if we had 3(5 + x), we would have 15 (3 * 5) + 3x (3 * x).
Hopefully that makes sense!

Answer:
slope : 3
y= 3x+2
Step-by-step explanation:
Answer:
Slope: 3 over 1 or 3
Y-intercept: 2
Equation: y = 3x +2
Step-by-step explanation:
Slope: You count up (or rise) from one point to another and you get 3. Then count right (or run) until you get to a point and you get 1. Slope is rise over run so 3 over 1 or simplified, 3.
Y-intercept: The point where the line crosses the y-axis. That is 2.
Equation: m=slope
b= y-intercept
So, y = 3x + 2

Step-by-step explanation:
Write the equation of the line, in slope-intercept form, with the following information slope:1/5 point: (20,-5)
Answer:
y = 1/5x - 1.
Step-by-step explanation:
Slope intercept form: y = mx + b
in this equation, the m is the slope (the amount the line moves vertically divided by the amount it moves horizontally from one point to another) and the b is the y-intercept (meaning where the line meets with the y-axis when graphed).
So, m is equal to 1/5 because that is the slope.
Now, to find b (the y-intercept), I am going to plug in the coordinate values of the point (20,-5) into the equation.
The 20 is the x coordinate and the -5 is the y-coordinate because the point is written in (x, y) form.
Here's how it looks with everything plugged in:
-5 = 1/5(20) + b.
The slope-intercept form is y = mx + b, and I just plugged in my values where
y (y-coordinate)= -5
m (slope)= 1/5
x (x-coordinate) = 20
Now that I know everything, I just need to solve for b, the y-intercept:
-5 = 1/5(20) + b.
-5 = 4 + b (simplified)
-1 = b
so, the y-intercept is -1.
Now, in slope-intercept form, the answer is: y = (1/5)x - 1.

Joey is standing on a diving board that is 5.6 feet above sea level. Joey dives into the water to a depth of -8.6 feet below sea level.
Answer:
14.2 feet
Step-by-step explanation:
I'm guessing the question is asking how far did Joey travel from the diving board.
Joey is 5.6 feet above 0 so to reach 0 we must subtract 5.6
-5.6 + - 8.6 = - 14.2 feet
Joey traveled 14.2 feet
You are saving for a new tablet? Suppose you have $200 to start, and you need to keep the money in a bank account. Plan A: An additional $20 per month will be added to your account each month.

Peyton is collecting data on the lunch habits of students at Hyattsville Middle School. In one class, 14 students bring lunch from home, and 20 buy a school lunch. Hyattsville Middle School has 1700 students. From the data collected, how many students would Peyton predict would buy a school lunch? *
Answer:
Answer: Around 1000 students would buy a school lunch.
Step-by-step explanation:
We know that in one class, 14 students bring lunch from home, and 20 buy lunch in the school. This will be our sample.
In total we have 20 + 14 = 34 students, this will be our 100%.
The percentage of students that bring lunch from home can be estimated as the quotient between the number of students that bring lunch from home and the total number of students, times 100%.
p1 = (14/34)*100% = 41.18%
And the percentage of students that buy lunch at school can be computed in the same way:
p2= (20/34)*100% = 58.82%
Then, out of the 1700 students in middle school, we can estimate that around 58.82% of them will buy lunch in the school.
Then the exact number will be:
N = (58.82%/100%)*1700 = 1000
Around 1000 students would buy a school lunch.

Answer:
PQ=30
Step-by-step explanation:
Knowing that the segment has 3 parts that are 3:1:1 and sum up to 50, you could find how much 1 would equal by finding the total in relation to the ratio (doing 3+1+1) which gets you 5 parts. Then you can divide the total (50) by 5 to figure out how much one part would equal (10). Now, since you know that 1 part is equal to 10 and that PQ is 3 parts, you can find that PQ is equal to 3x10, or 30.
