Solve the inequality 6x+1<5x−8.
Certainly! Let's solve the inequality 6x+1<5x-8 step-by-step:
6x + 1 < 5x - 8
We can start by subtracting 5x from both sides to isolate the x term:
6x - 5x + 1 < 5x - 5x - 8
This simplifies to:
x + 1 < -8
Next, we can subtract 1 from both sides to isolate the x term:
x + 1 - 1 < -8 - 1
This simplifies to:
x < -9
So the solution to the inequality is x < -9.
Shantel offers online tutorial services. She charges $25.00 an hour per student. Her budget tracker reflects a total of $3,200.00 monthly expenses. How many hours must Shantel work each month to earn a monthly profit of at least $600.00?(1 point)
Let's assume the number of hours Shantel needs to work each month is represented by "h".
Shantel charges $25.00 per hour per student, so her revenue for the month can be calculated as 25h.
Her total expenses are given as $3,200.00.
To calculate her profit, we subtract the expenses from the revenue:
Profit = Revenue - Expenses
Profit = 25h - 3200
We want Shantel to earn a profit of at least $600.00, so we can set up the following inequality:
25h - 3200 ≥ 600
Adding 3200 to both sides of the inequality, we have:
25h - 3200 + 3200 ≥ 600 + 3200
25h ≥ 3800
Lastly, we divide both sides of the inequality by 25 to solve for h:
h ≥ 3800 / 25
h ≥ 152
Therefore, Shantel must work at least 152 hours each month to earn a profit of at least $600.00.
La’Shondra solves the inequality 6+3x≤24. She begins by subtracting 6 from both sides of the inequality and then divides both sides of the equivalent inequality by a number. What is the number?(1 point)
To solve the inequality 6 + 3x ≤ 24, let's go through the steps as described:
1. Subtract 6 from both sides of the inequality:
6 + 3x - 6 ≤ 24 - 6
3x ≤ 18
2. Now to isolate the variable x, you mentioned that La'Shondra divides both sides of the inequality by a number. In this case, we need to divide both sides by 3:
(3x) / 3 ≤ 18 / 3
x ≤ 6
Therefore, the number that La'Shondra divides both sides of the inequality by is 3.
Solve the inequality Rx>10, where R is a number greater than 0.(1 point)
To solve the inequality Rx > 10, where R is a number greater than 0, we can divide both sides of the inequality by R. However, since R can be any positive number, we need to consider two cases separately:
Case 1: R > 0
If R is positive, we can safely divide both sides by R without changing the direction of the inequality:
(Rx) / R > 10 / R
x > 10 / R
Case 2: R = 0
If R is equal to zero, then the inequality Rx > 10 does not hold, since any number multiplied by zero is still zero. Therefore, we exclude this case.
In conclusion, when R is any positive number greater than 0, the solution to the inequality Rx > 10 is x > 10 / R.
Solve the inequality Ay+3<12, where A is a number greater than 0.(1 point)
To solve the inequality Ay + 3 < 12, where A is a number greater than 0, we can subtract 3 from both sides of the inequality:
Ay + 3 - 3 < 12 - 3
Ay < 9
Now, we can divide both sides of the inequality by A. Since A is greater than 0, we don't need to consider any separate cases:
(Ay) / A < 9 / A
y < 9 / A
Therefore, when A is any number greater than 0, the solution to the inequality Ay + 3 < 12 is y < 9 / A.
