Solve the inequality 6x+1<5x−8
.(1 point)
x
To solve the inequality 6x + 1 < 5x - 8, we need to isolate the variable x on one side of the inequality.
First, subtract 5x from both sides:
6x + 1 - 5x < 5x - 8 - 5x
This simplifies to:
x + 1 < -8
Next, subtract 1 from both sides to isolate the x term:
x + 1 - 1 < -8 - 1
This simplifies to:
x < -9
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)
at least
hours
To calculate how many hours Shantel must work each month to earn a profit of at least $600, we need to consider her expenses and the revenue she generates from tutoring.
Let's assume she works x hours per month.
Revenue from tutoring: $25.00/hour x x hours = $25x
Expenses: $3,200.00
To calculate the profit, we subtract the expenses from the revenue:
Profit = Revenue - Expenses
Profit = $25x - $3,200.00
We want the profit to be at least $600, so we can set up the following inequality:
$25x - $3,200.00 ≥ $600.00
Adding $3,200.00 to both sides:
$25x ≥ $600.00 + $3,200.00
$25x ≥ $3,800.00
Now, we can divide both sides by 25 to solve for x:
x ≥ $3,800.00 / $25.00
x ≥ 152
Shantel must work at least 152 hours per month to earn a profit of at least $600.
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, La’Shondra begins by subtracting 6 from both sides of the inequality:
6 + 3x - 6 ≤ 24 - 6
3x ≤ 18
Next, to solve for x, she needs to divide both sides of the inequality by a number. In this case, the number she needs to divide by is 3.
Dividing both sides by 3:
(3x) / 3 ≤ 18 / 3
x ≤ 6
Therefore, the number she divided both sides by is 3.
