Can someone please professionally explain the math equation. (Not just answer the question)
12b + 12 ≥ 60
SOLVE the inequality.
GRAPH the solution.
Make sure to solve and graph the equation please.
I will mark as brainliest!
Answer:
b ≥ 4
Step-by-step explanation:
12b + 12 ≥ 60
Subtract 12 from each side
12b + 12-12 ≥ 60-12
12b ≥ 48
Divide each side by 12
12b/ 12 ≥ 48/12
b ≥ 4
Close circle at 4 line to the right
Answer:
Step-by-step explanation:
12b + 12 ≥ 60
1) add -12 at both members
12b + 12-12 ≥ 60 -12
12b ≥ 48
2) divide both members by 12
12/12 b ≥ 48/12
b ≥ 4
for graph the solutions we have to draw two lines
the first one is an horizontal line that has as equation the right part of the inequality
y = 60
the second one is a line the that passes from the origin and interecpts the first line in (4;60). 4 is the the first number that can be a possible value of the inequality
Equation a line that passes for two points A (0,0) , B (4,60)
(y-y1)/(y2-y1) = (x-x1)/(x2-x1)
(y - 60)/ (0 -60) = (x - 4) / (0-4)
(-y+60)/60 (-x+4)/4
-y + 60 = -15x + 60
y = 15x
the solutions of the inequality are all the points between the two lines with x≥4 and y≥60
What is the value of x in the equation 2(5x + 4) = 17?
A 5/2
B 2/5
C 9/10
D 17/18
Answer:
[tex]\frac{9}{10}[/tex]
Step-by-step explanation:
[tex]2(5x+4)=17,\\10x+8=17,\\10x=9,\\x=\frac{9}{10}[/tex]
Analysis:
2(5x+4)=17
Distribute10x+8=17,
Subtract 8 from both sides to isolate x10x=9
Divide both sides by 10 to isolate xx=9/10 (ans)
Answer:
x = 9/10
Step-by-step explanation:
2(5x + 4) = 17
Distribute
10x+8 =17
Subtract 8 from each side
10x +8-8 = 17-8
10x = 9
Divide by 10
10x/10 = 9/10
x = 9/10

Answer:
He traveled 520 miles
Step-by-step explanation:
8 x 65 = 520
Answer: 520 miles
Step-by-step explanation:
Data: Juan drove 8 hours
Drove at an average Speed of 65 mph
Miles driven=x
Only step: Multiply 65 by 8 which is 520
Explanation: Since Juan drove at an average speed of 65 miles per hour, that means he drove 65 mile for every hour he drove. So since he drove for 8 hours, you multiply 8 hours by 65 miles so that you get get the total amount of hours driven by him.
Don't forget to add "Miles" to the end of your answer because most math teachers tend to want that in an answer like this.

Answer:
Oki Doki, read below this will be long.
Step-by-step explanation:
So, lets start with mr moy.
First off, we need to figure out the total hours that mr moy worked.
Throuhgout the 7 days of the week, he worked 5 days. These were his hours:
8, 8, 8, 8, 9
Adding these together, you get a total of 41 hours.
Next we have total wage.
To find this, multiply the total hours by the hourly income. We know the hourly income is 12.5, and the total hours is 41:
12.5*41=512.5
So 512.5 is the total wage.
Lets do this for the next four people, I am just going to speed it up a bit:
Ms wong - hours - 8+8+7+9+9 =41. Hourly income - 9.5. Total income: 9.5*41:
389.5 is total income
41 is total hours
Maria - hours - 5+5+6+8+9=33. Hourly income - 7.5. Total income: 7.5*33:
247.5 total income
33 total hours
Tom - 4+4+4+4+4+8+8=36. Hourly income - 7.5. Total income: 7.5*36:
270 total income
36 total hours
Jacob - 5+5+5+7+7 =29. Hourly income - 7.5. Total income: 7.5*29:
217.5 total income
29 total hours
OK, now for the total sums:
Total hourly wages - 7.5+7.5+7.5+12.5+9.5=44.5
Total of the total hours - 41+41+33+36+29=180 hours
Total of total wages - 217.5+512.5+389.5+270+247.5=1637
Ok, thats it for the first page.
On the next pages, I was slightly confused. But Ill try my best.
A - for each employ, calculate total hours and wages. We already did this before.
B - What is the total amount that is paid out in wages in a week. We already did this before(1637)
C - which day is the busiest day of the week - Saturday. The slowest? Monday
So we know the slowest day has to be monday, since the total employment hours is 8+8+4=20. WHich is lower than the rest.
We also know the busiest day has to be saturday, since the total employment hours is 9+9+8+5=31. Which is higher than the rest.
Now to the the third page.
What is the average employe wage?
Lets add up all the wages, and divide by the amount of wages:
7.5+7.5+7.5+9.5+12.5=44.5
44.5/5
=
8.9
This is the average wage.
I dont totally understand part b or c of this answer.
I cannot draw or make a graph and table right now, so I cannot finish your answers.
I hope these help though!

A $100 MP3 player is marked up by 10% and then marked down by 10%. What is that final price?
Answer:
$99
Step-by-step explanation:
MP3 Player: $100
10% Mark up: $100/10= 10
Therefore, Mark-Up Price: $100+$10= $110
This was then Marked down by 10%.
Therefore,
10% Marked down: $110/10= $11
(We then take this away from the marked up price)
Hence, Final Price : $110-$11= $99

Answer:
382.50
Step-by-step explanation:
Area of the Shaded region = Area of the larger triangle - Area of the smaller triangle;
Let's find the area of the large triangle first;
A = 1/2(base) * (height)
A = 1/2(33) * (33)
A = 16.5 * 33
A = 544.5
Now let's find the area of the small triangle;
A = 1/2(base) * (height)
A = 1/2(18) * (18)
A = 9 * 18
A = 162
Area of the shaded region;
=> 544.5 - 162
=> 382.5 (if rounded to the nearest hundredths, 382.50)
Hope this helps!

Find the distance between (1, -5) and (-6, 2).
**If necessary, round to the nearest tenth**
98 units
34 units
9.9 units
5.8 units
Answer:
d = 9.9 units
Step-by-step explanation:
Picture a right triangle with one acute vertex at (1, -5) and the other at (-6, 2). Going from one to the other, we see a change in x (run) of 7 and a change in y of 7. Applying the Pythagorean Theorem, we find the distance between the two points as follows:
d = √(7² + 7²) = 7√2, or approximately 9.9 units.
The figure shows two parallel lines cut by a transversal. what is the measure in degrees of angle ABC?
Answer:
70
Step-by-step explanation:
2x and (4x-70) have the same measurements.
Set your formula up as
2x = 4x-70
2x-4x=-70
-2x=-70
x=35
Now substitute 35 in place of x
2x = 2*35 = 70
4x-70 = 4*35 - 70 = 70

A class' test scores are normally distributed with a mean of 48 points and a standard
deviation of 3 points. What percentage of test scores are are between 47 and 52
points? Round to the nearest hundredth of a percent.
Answer:
53.94%
Step-by-step explanation:
We solve using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean = 48 points
σ is the population standard deviation = 3 points
For x = 47 points
z = 47 - 48/3
= -0.33333
Probability value from Z-Table:
P(x = 47) = 0.36944
For x = 52 points
z = 52 - 48/3
= 1.33333
Probability value from Z-Table:
P(x = 52) = 0.90879
Hence, the probability of test scores that between 47 and 52 points is calculated as:
P(x = 52) - P(x = 47)
= 0.90879 - 0.36944
= 0.53935
Therefore, the percentage of test scores that are between 47 and 52
points is given as:
0.53935 × 100
= 53.935%
Approximately to the nearest hundredth of a percent ≈ 53.94%

Answer:

624,612 rounded to the nearest hundred is
Answer:
624 600
Step-by-step explanation:
624 612
you have to concentrate at the 1 because because it's at the tens place, if the 1 is not greater than 5 you don't have to do anything. you just have to remove the two numbers before the the number 6 and you so it automatically should be 624 600.
To round a number to the nearest hundredth , look at the next place value to the right (the tens this time). Same deal: If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the hundredths place, and then remove all the digits to the right.
A soccer field is 110 yards long and 80 yards wide. What is the longest pass that one player can make to another player on a soccer field?
Answer and Step-by-step explanation:
To find the answer, we need to first think of what length in the rectangle can make the longest path, then use the Pythagorean Theorem.
The diagonal in a rectangle (going from one corner to another) is the longest distance.
If we were to split that rectangle by its diagonal, we would get a triangle. By the Pythagorean Theorem, we can find the length of that diagonal (the hypotenuse of the triangle).
[tex]A^2 + B^2 = C^2\\\\110^2+80^2 = C^2\\\\12100 + 6400 = C^2\\\\18500 = C^2\\\\10\sqrt{185} = C = 136.0147 yards[/tex] <- This is the answer (the decimal version or this ^ version).
