I need some help with checking my awnsers on a math quiz please.
1. Solve the equtaion. 3x-3=_18
2. 12+4m=24
3. No more then 12 people can enter the haunted house every 10 minetus. Write an inequality.
4. Solve the inequlity. d-6>_4
Is 44 <,>,= to 21+18
1. To solve the equation 3x - 3 = 18, you need to isolate the variable x.
First, add 3 to both sides of the equation:
3x - 3 + 3 = 18 + 3
This simplifies to:
3x = 21
Then, divide both sides of the equation by 3 to solve for x:
(3x)/3 = 21/3
This simplifies to:
x = 7
So, the solution to the equation 3x - 3 = 18 is x = 7.
2. To solve the equation 12 + 4m = 24, you need to isolate the variable m.
First, subtract 12 from both sides of the equation:
12 + 4m - 12 = 24 - 12
This simplifies to:
4m = 12
Then, divide both sides of the equation by 4 to solve for m:
(4m)/4 = 12/4
This simplifies to:
m = 3
So, the solution to the equation 12 + 4m = 24 is m = 3.
3. In order to write an inequality for the statement "No more than 12 people can enter the haunted house every 10 minutes," you should use the less than or equal to symbol (≤).
Let's let p represent the number of people entering the haunted house. Since there can be no more than 12 people, we can write the inequality as:
p ≤ 12
4. To solve the inequality d - 6 ≥ 4, you need to isolate the variable d.
First, add 6 to both sides of the inequality:
d - 6 + 6 ≥ 4 + 6
This simplifies to:
d ≥ 10
So, the solution to the inequality d - 6 ≥ 4 is d ≥ 10.
We'll be glad to check your answers.
