Answer:
x=47
Step-by-step explanation:
Let's solve your equation step-by-step.
180=x+3x−8
Step 1: Simplify both sides of the equation.
180=x+3x−8
180=x+3x+−8
180=(x+3x)+(−8)(Combine Like Terms)
180=4x+−8
180=4x−8
Step 2: Flip the equation.
4x−8=180
Step 3: Add 8 to both sides.
4x−8+8=180+8
4x=188
Step 4: Divide both sides by 4.
4x4=1884
x=47

Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, then m=m equals negative StartFraction 1 Over 6 EndFraction.. What is the value of b?
Answer:
We get value of the value of b = 5
Step-by-step explanation:
Line AB passes through points A(−6, 6) and B(12, 3). If the equation of the line is written in slope-intercept form, y=mx+b, then m=m equals negative StartFraction 1 Over 6 EndFraction.. What is the value of b?
We have slope m: [tex]m=-\frac{1}{6}[/tex]
We need to find value of b (y-intercept)
Using the point A(-6,6) and slope [tex]m=-\frac{1}{6}[/tex] we can find b.
Using slope-intercept form, putting values of m and x and y we get the value of b:
[tex]y=mx+b\\6=-\frac{1}{6}(-6)+b\\6=1+b\\b=6-1\\b=5[/tex]
So, we get value of the value of b = 5

Enter the formula to find the surface area of a prism involving area of the Base and Perimeter of the base
Answer:
p=3+4+5=12
Step-by-step explanation:
Answer:
96 inches2 or 352 cm2
Step-by-step explanation:
-Okay so, we know that The lateral surface area of a prism is the sum of the areas of its lateral faces. And The total surface area of a prism is the sum of the areas of its lateral faces and its two bases. Then Usually, if "right" or "oblique" is not mentioned, you can assume the prism is a right prism. The general formula for the lateral surface area of a right prism is L.S.A.=ph where p represents the perimeter of the base and h represents the height of the prism.
A large bakery produces cakes in an assembly line. Sergio noticed a potential defect that seems to be showing in
every other cake. He decides that in the next production run, he'll take a random sample of cakes to get a better
idea of how many cakes might have this defect.
Why might Sergio choose a simple random sample instead of a systematic random sample?
The system random sampling involves the introduction of a sampling interval during the sampling process. Hence, the use of a fixed interval is more likely to miss the potential defect noticed based on the sampling interval selected.
The systematic random sampling simply involves choosing a fixed sampling interval during the sampling process. A simple random sampling however selects a truly random sample from a population and this techniques provides the best sample which is representative of the population. Since a sampling interval is required for a systematic random sample, the sample obtained for different values of k, which is the sampling interval will differ leading to a potential risk of missing the target .Therefore, with simple random sampling, Sergio stands a better chance of capturing the defect better than using systematic random sampling

Answer:
If the defect is in every other cake, a systematic random sample could miss it completely depending on what Sergio chooses for kkk.

Jorie leaves work 30 minutes late. She decides to make up time by taking the toll road instead of side streets. She can travel four times faster by taking the toll road. Create an equation to represent her total travel time, including wait time, where x is the number of minutes the drive was expected to take.
y equals one fourth times x minus thirty
y = 4x − 30
y equals one fourth times x plus thirty
y = 4x + 30
Answer:
option C
Step-by-step explanation:
We know that the toll road is 4 times faster than the side streets.If 'x' represents the number of minutes she usually spend taking the side streets. The represents the time she takes taking the toll road.Also we need to create an equation to represent her total travel time, including wait time

Twice a number added to another number is 15. The sum of the two numbers is 11. Find the numbers. Write the numbers from least to greatest
Answer:
4 and 7
Step-by-step explanation:
There are probably several ways to do this but this is how I did it:
First, I listed all the number combinations, that added together equaled 11.
This is what it looked like:
1, 10
2, 9
3, 8
4, 7
5, 6
6, 5
7, 4
I stopped here since the next step would be to double the first number and 8*2 would already be more than 15.
Then, I doubled the first number and added the second number to it, when I saw that didn't equal 15, I eliminated that possibility and moved on to the next set of numbers. When I reached 4, 7 I saw that 4*2 equaled 8 and 8 plus 7 equals 15 so I had the answer.
There are probably much more efficient ways to do this but this is how I did it.
Hope it helped!
The first number is 4 and second number is 7.
Let us consider that first number is x and second number is y.
[tex]2x+y=15\\\\x+y=11[/tex]
Substitute [tex]y=11 - x[/tex]in equation [tex]2x+y=15[/tex]
[tex]2x+11-x=15\\\\x=15-11=4[/tex]
So, [tex]y=11-x=11-4=7[/tex]

mowing lawns earns $10.00 for 1 hour and $42.00 for 5 hours. what is the slope
Answer:
The slope is $8 per hour
Step-by-step explanation:
Here, we want to get the slope of the relation
Mathematically, that will be;
m = y2-y1/x2-x1
Where ; (no of hours, money) represents each point
Thus, we have it that
m = (42-10)/(5-1) = 32/4 = $8/ hour
Jane is thirteen years younger than twice Ruby’s age. Nora is 5 years older than Ruby. If their ages sum to 52, find each girl’s age.
Answer:
J=17 N=20 R=15
Step-by-step explanation:
J=Jane
R=Ruby
N=Nora
J=2R-13
N=5+R
J+N+R=52
(2R-13)+(5+R)+R=52
Slove for R and plug into each equation
Answer:
Ruby is 15, Jane is 17 and Nora is 20.
Step-by-step explanation:
Let x represent the age of Ruby.
Jane: 2x - 13
Ruby: x
Nora: x + 5
52 = (x) + (2x - 13) + (x + 5)
52 = x + 2x - 13 + x + 5
52 + 13 - 5 = x + 2x + x
60 = 4x
x = 15
Jane:
2(15) -13
= 17
Nora:
(15) + 5
= 20
