Answer:
a = -0.6b + 0.2c
Step-by-step explanation:
Simplifying
5a + 3b = c
Solving
5a + 3b = c
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-3b' to each side of the equation.
5a + 3b + -3b = -3b + c
Combine like terms: 3b + -3b = 0
5a + 0 = -3b + c
5a = -3b + c
Divide each side by '5'.
a = -0.6b + 0.2c
A general equation of a linear function is expressed as y = mx + b where m represents the slope and b is the y-intercept. The slope is the rate of change of y with respect x which is equal to 4 for this problem. The y-intercept represents the value when x is equal to zero. It is the initial value of y. In this case, it is equal to $1,000. The linear equation would be:
y = 4x + 1000
assuming y is the income and x is the consumption.
At an income (y) equal to $20,000, we can calculate for the consumption.
20000 = 4x + 1000
19000 = 4x
x = 4750
Answer:
3 musicans
Step-by-step explanation:
Hello there! Your answer is approximately 14 students.
To solve this question, you want to start by finding 40% of 24. To do this, convert 40% into a decimal (divide by 100) and multiply by 24.
24 x 0.40 = 9.6.
But - you can't have 9.6 of a student. So, we round up to 10.
Note that the question asks how many students <em>still need to complete</em> their assignment, meaning we are looking for the ones that haven't finished. We found the amount for students that <em>have</em> finished, so subtract that from the total to see approximately how many still have to finish.
24 - 10 = 14
So, this means approximately 14 students still need to complete their assignment.
I hope I could help you, have a great rest of your day! :D
