Answer:
The symbols that we will use are:
a > b (a is larger than b)
a < b (a is smaller than b)
a ≥ b (a is larger than or equal to b)
a ≤ b (a is smaller than or equal to b).
1) if x represents the inches of snow, we have:
"More than 4 inches" means that x must be strictly larger than 4 inches, this can be written as:
x > 4 inches.
2) "less than 25 inches" means that x must be strictly smaller than 25 inches, this can be written as:
x < 25 inches.
3) If T represents the temperature
"No more than 8°F" means that the temperature can be smaller than 8°F, or equal to 8°F, then we can write this situation with:
T ≤ 8°F
4) "At least 7°F" means that the temperature can be 7°F or more than that, then we can write this situation as:
T ≥ 7°F
Answer:
Step-by-step exA wall is 1200 sq ft.
A gallon of paint covers 200 sq ft.
Complete the conversion factor: 1 gallon / ? sq ftplanation:
5(squareroot(3)) would be simplest radical form.
Example problem:
2x+58=5x-2
First we need to get the variable on one side so we can do that by subtracting 2x from both sides.
58=3x-2
Then we need to isolate our variable to make it by itself on one side. We can do that by adding 2 to both sides.
60=3x
Finally divide each side by 3 and you end up with x=30.
(If you end up with something like 30=30 that means there are infinite solutions. If you end up with something like 24=30 there are no solutions.)
I hope this helps! If you have any questions you can reply and I will try to get back as soon as possible.
