Answer:
x = 20
Step-by-step explanation:
To solve this, your goal should be to get x by itself in front of the equal sign. To do this, first add 12 to both sides of the equal sign. This gets rid of the -12 since -12 + 12 = 0.
3x - 12 + 12 = 48 + 12
3x = 60
The last step is to divide 3 from both sides.
3x / 3 = x.
60 / 3 = 20.
This leaves you with x = 20 which is the answer.
0.16, just put a line over the six so it can show its repeating
Answer:
The answer to your question is 10 units ²
Step-by-step explanation:
To solve this problem I will use the formula
3 3
A = 1/2 3 -1 = 1/2 [ (3 x -1) + (3 x -5) + (-2 x 3) - (3 x -5) - (-2 x -1)
-2 -5 -(3 x 3)]
3 3 = 1/2 [ -3 - 15 - 6 + 15 - 2 - 9]
= 1/2 [ -20]
= 1/2|20|
= 10 units²
Sorry, I don't remember how to use the formula 1/2 b x h
Answer:
12/4 and 3/5 =x42 2 then 3/9 and 2/27 = x24
Step-by-step explanation:
Answer:
Since, an airplane descended 4,000 feet before landing.
Now, we have to determine the integer which represents the number of feet, the airplane was above the ground before its descent.
Before the descent, airplane was at the height of 4,000 feet.
And the distance above the ground is represented by the positive integers and distance below the ground is represented by the negative integers.
Since, 4,000 feet is the distance of airplane above the ground.
So, the airplane was +4,000 feet above the ground before its descent.
