The answer is 2 for 5.80 is cheaper for buying 30 t-shirts.
Answer:
67 mph
Step-by-step explanation:
Well the average speed is miles per hour so simply its 301.5 miles and 4.5 hours
which to see how many miles in one hour:
301.5/4.5 = 67
Answer: FALSE.
Step-by-step explanation:
Given the following equation provided in the exercise:

You need to solve for the variable "x".
In order to solve for "x" you can folllow the steps shown below:
1. You must apply the Addition property of equality and add 13 to both sides of the equation. Then:

2. Finally you need to apply the Subtraction property of equality and subtract "x" from both sides of the equation. So you get:

Therefore, as you can observe, the given equation has no solutions.
Answer:
3. 0
4. n = -2
Step-by-step explanation:
I haven't taken pre-calc but this looks a lot like algebra.
For #3, just plug in -2 for the x values, so:
x^2 + 4x +4
(-2)^2 + 4(-2) + 4
= 4 - 8 + 4
= 0
For #4, move the variables to one side and solve( im not sure what the pi is for tho, or is that a n?):
5n + 6 = -3n - 10
add 3n to both sides
8n + 6 = -10
subtract 6 from both sides
8n = -16
divide both sides by 8
n = -2
