h=[
Answers
To solve for h:
Factor out h from the right-hand side of the equation:
f = h(5g)
Divide both sides by (5g):
f /(5g) = h(5g)/(5g)
f/5g = h

Jack had m that problems to complete during his vacation. He solved the same number of problems every day and finished them all in 5 days. How many problems did Jack solve per day?
Answers
Answer: 1 problem per day
Step-by-step explanation:
m/5 problems completed in 5 days.
substite m with 5 because 5 days
5/5
5/5=1
Therefore Jack solved 1 question per day.
The number of problems Jack solve per day is 4 problems.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
We are given that;
Number of days= 5days
Now,
To find how many problems Jack solved per day, we need to divide the total number of problems by the number of days. This is because he solved the same number of problems every day. So, we can write an equation as:
m / 5 = p
where m is the total number of problems and p is the number of problems per day.
To solve for p, we need to multiply both sides of the equation by 5 and get:
p = m
This means that Jack solved m problems per day.
For example, if m = 20, then Jack solved 20 / 5
= 4 problems per day.
Therefore, by algebra the answer will be 4.

If cost is represented by C(x)=1.8x+10,000 and revenues are represented by R(x)=8.5x, which equation could be used to find the break-even point?
Answers
Answer:
8.5x=1.8x+10,000
Step-by-step explanation:
The break-even point is the point where the expressions for the functions have the same value: 8.5x=1.8x+10,000.
A missile uses an internal computer clock to measure time in tenths of a second. The missile guidance system needs the time from launch, in seconds, in order to calculate its distance from the launch site. It obtains this by multiplying the computer clock time by 0.1. So, for example, a reading of 50 tenths of a second is 5 seconds. For one particular missile system, the conversion factor of 0.1 is stored in 8 bits as the binary number 0.000110012.
The missile’s internal computer clock shows 200 tenths of a second. Convert this to seconds using your result from Part (i) of this question. Do not round your answer. The missile guidance system now records that it has travelled for this number of seconds.
Answers
Using proportions, it is found that the missile's internal computer clock is of 20 seconds.
According to the information given, this question can be solved by proportions, using a rule of three.50 tenths of a second is equivalent to 5 seconds, and we want to find the equivalent to 200 tenths of a second, thus, the rule of three is:
50 tenths - 5 seconds
200 tenths - x seconds
Applying cross multiplication:
[tex]50x = 5(200)[/tex]
[tex]50x = 1000[/tex]
[tex]x = \frac{1000}{50}[/tex]
[tex]x = 20[/tex]
The missile's internal computer clock is of 20 seconds.

62 points! a bus traveled on a level road for 3 hours at an average speed of 20 miles per hour faster than it traveled on a winding road. The time spent on the winding road was 6 hours. Find the average speed on the levelroad if the entire trip was 482 miles.

Answer:
≈ 66.89 mphStep-by-step explanation:
Let the average speed on the level road was x.
Then the average speed on the winding road was x - 20.
The total distance is:
3x+ 6(x - 20) = 4823x + 6x - 120 = 4829x = 482 + 1209x = 602x = 602/9x ≈ 66.89 mphQUESTION 18

[tex]\sqrt{4x^2}=2|x|[/tex]
Step-by-step explanation:
We are given the radical [tex]\sqrt{4x^2}[/tex] and we have to simplify it down as much as possible.
We first will have to find out what numbers are inside the square root, we can see that there is a 4 and an [tex]x^2[/tex], of which both can be taken out of the square root by simplification.
The square root of 4 is 2, and the square root of [tex]x^2[/tex] is [tex]x[/tex].
Due to how radicals work, we have to multiply 2 and [tex]x[/tex], but before that, we have to preserve how the radical was beforehand. We know that a radical cannot have a negative radicand, and due to that we must add absolute value to keep the equation's original status the same.
To sum it all up, our answer is [tex]2|x|[/tex], due to us simplifying it down, and applying absolute value to preserve the answer before it was simplified.

Answer:
3x was subtracted from the left side, but 3x was subtracted from the right side. The Subtract Property of Equality states that you can subtract the same number from each side and the equation will remain true. But 3x and 3 are not the same number (unless x is 1).
x = -8/5
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
[tex](7x+3x)+(21)=5[/tex] [tex]10x + 21 = 5[/tex]Step 2: Subtract 12 from both sides.
[tex]10x + 21 - 21 = 5 - 21[/tex] [tex]10x = -16[/tex]Step 3: Divide both sides by 10.
[tex]\frac{10x}{10} = \frac{-16}{10}[/tex] [tex]x = -\frac{8}{5}[/tex]9514 1404 393
Answer:
3x31x = -1.6Step-by-step explanation:
You answer this sort of question by comparing each line to the line above to see what the differences are. In the second line, the term 3x is missing from the left side of the equal sign, and the value 5 has been changed to the value 2 on the right side. The wording of the statement you're to fill in tells you that it should read ...
3x was subtracted from the left side, but 3 was subtracted from the right side.
... 3x and 3 are not the same number (unless x is 1 .)
__
The correct solution is ...
7x +21 +3x = 5 . . . . . . given
10x +21 = 5 . . . . . . . . . collect terms
10x = -16 . . . . . . . . . . . subtract 21 from both sides
x = -1.6 . . . . . . . . . . . . divide both sides by 10

Additional comment
It can often work well to "read ahead" when answering a question or series of questions. The later questions or comments often provide clues that help you understand how to answer the earlier questions.
Here, for example, it becomes clear that 3x and 3 were subtracted from the different sides of the equation. You can find that out simply by reading the rest of the statement you're to fill in. These are the answers to the questions asked in the first part of the statement.
