Similar to one-step and two-step equations, the basic objective of multi-step problems is to isolate the unknown variable on one side of the equation while maintaining the constant or number on the other side.
Solving a 3-step problem typically involves the following steps:
Read the problem carefully and understand what it is asking for. Make sure you know what the given information is and what you need to find.Identify the relevant information and decide what you need to do with it. You may need to do some calculations or use some formulas to help you solve the problem.Use the appropriate steps to solve the problem. Make sure you show all of your work and double-check your solution to make sure it is reasonable.It can be helpful to break the problem down into smaller parts and solve each part separately. This can make the problem feel more manageable and help you avoid making mistakes.
If you get stuck at any point, it can be helpful to take a break and come back to the problem later, or to ask someone for help.

Add fractions with unlike denominators
Answer:
2.1
Step-by-step explanation:
Natasha conducted a survey to determine how many of the 215 workers in her office building use public transportation to get to work. She surveyed 30 randomly selected workers who entered the office cafeteria throughout the day. Of the 30 workers surveyed, 9 used public transportation to get to work.
Which change to Natasha's survey process would make the data more reliable?
A. Ask a randomly selected sample of people who use public transportation whether their office is in the building.
B. Use a different sample size so the predicted number of workers who use public transportation is a whole number.
C. Have workers complete a written survey so there is a written record of the responses.
D. Randomly select the sample in the lobby of the building so workers who do not enter the cafeteria can be included.

Find the measure of CGD.
Answer:
23°
Step-by-step explanation:
For this scenario say point G is the center point,
If we look to the left, we see angle FGE has a value of 23
and in this case angle CGD is a congruent angle to FGE therefore the two angles must be the same
so therefore angle CGD should be 23 degrees

The ratio of mango ice cream to strawberry ice cream is 2 : 5 .Total no. of ice cream is 49.what is the no. of strawberry ice cream.
Answer:
35
Step-by-step explanation:
First, we add the ratio of the mango to strawberry ice cream and we're going to end up with 2+5=7. If we divide 49 by 7, we're going to find out how much we need to multiply to both sides of the ratio to get the specific amounts. So, if we multiply 7 (49/7) to 5, we're going to get 35. Therefore the number of strawberry ice cream is 35.
Also, we can check this by multiplying 7 to 2 as well, where we will end up with 14. 35 + 14 = 49 so we know this is correct!
35 is Answer:
Step-by-step explanation: if you do 2:5 and like keep doing it you'll get to a number and another one and it'll make 49

Find the slope of the line with x intercept 9 and y intercept of -2
Answer:
2/9
Step-by-step explanation:
Find the slope of the line with x intercept 9 and y intercept of -2
Given that the equation of the line is y = mx+b
x intercept occurs when y = 0
The coordinate of x intercept is (9,0)
y intercept occurs at x = 0
The coordinate of y intercept is (0, -2)
Slope m = y2-y1/x2-x1
m = -2-0/0-9
m = -2/-9
m = 2/9
Hence the required slope is 2/9

Teresa is going to make 3 batches of cookies. She needs 3/4 milk for each. Her measuring cup only holds 1/4 gallon. How many tines will she need to fill up the measuring cup 3 times
Given :
Teresa is going to make 3 batches of cookies.
She needs 3/4 milk for each. Her measuring cup only holds 1/4 gallon.
To Find :
How many times will she need to fill up.
Solution :
Amount of milk need per batch, A = 3/4 gallon.
Measuring cup only holds, m = 1/4 gallon.
Number of times she need to fill up,
n = A/m = (3/4)/(1/4) = 3
Now, number of batches are three.
So, number of time she need to fill up in three batch.
[tex]N = n \times 3 \\\\N = 3 \times 3 \\\\N = 9[/tex]
Therefore, this is the required solution.
Given the arithmetic sequence where an= 3 + 2(n-1), what is the domain for n?
Answer:
The set of all positive integers equal to or greater than 1
Step-by-step explanation:
n can take on the integer values 1 ... ∞
The formula for the nth term is a(n) = a(1) + 2(n - 1)
First term: n = 1. Then a(1) = 3 + 2(0) = 3 (as expected).
5th term: n = 5. Then a(5) = 3 + 2(5 - 1) = 3 + 8 = 11
...
and so on.
