Okay first you need to do distribute the -3 to remove the parentheses:
y - 4 = -3x + 9
Then you need to move -4 to the right by adding on both sides
y = -3x + 9 + 4
The answer is —> y = -3x + 13
Answer:
x must be 14/4 = 7/2
Step-by-step explanation:
The sum of the three interior angles of a triangle must be 180 degrees.
Thus, in this particular case,
82 + 64 + 4x + 20 = 180, or
146 + 4x = 160, or
4x = 160 - 146 = 14
Then 4x = 14, and x must be 14/4 = 7/2
Answer:
2.63
Step-by-step explanation:
29/11=2.63
Answer:
The value of 'x' is 31 unit
Step-by-step explanation:
Given:
Measure of each side = 
Perimeter of sails = 63 units.
We need to find the value of x.
Solution:
Now we can see that from given data.
A sailboat's Saul has three sides.
Now assuming it to be triangle we get;
"Perimeter of triangle is equal to sum of all side."
So we can say that;

Now adding both side by 30 we get;

Now dividing both side by 3 we get;

Hence the value of 'x' is 31 units.
