Answer:
0 < cc + dd ≤ 11
Step-by-step explanation:
≤ means equal to or less than.
It has to be more than zero, obviously.
The answer is yes. If you solve both expressions it would be 5m-10.
Answer:
0.26 minutes
Step-by-step explanation:
So if you want to solve this, you need to make all the units the same first. What you first need to work on is the rate, since what it is asking is minutes given distance in feet.
We know that there are:
5280 ft in a mile
60 minutes in an hour
We then convert the rate knowing this:

In short, the car is traveling 3,828 ft every minute.
To determine how many minutes it will take for the car to travel just remember that:

Now we plug in what we know and solve what we don't know:

Answer:
10, -10
Step-by-step explanation:
Take the sqrt(100)
What number times itself = 100
10*10 = 100
-10*-10 = 100
sqrt(100) = +10 or -10
Answer:
x = 27
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is number of sides
Here n = 7 , then
sum = 180° × 5 = 900°
sum the interior angles and equate to 900
3x + 31 + 135 + 5x - 4 + 7x - 64 + 120 + 6x - 8 + 4x + 15 = 900 , that is
25x + 225 = 900 ( subtract 225 from both sides )
25x = 675 ( divide both sides by 25 )
x = 27
