First of all move all the Xs to the left side, and the numbers to the left.
So
x/2-x = -13
Which means
X/2-x/1 = -13
Which means x/2-2x/2 = -13
So u combine to two fractions
-x/2 = -13
-x = -13 * 2
Which means x = 26 (u flip the negativity)
Answer: Yes
Step-by-step explanation:
The ratios of number found to the number of days are all equal to 14 fossils per day.
(Plus I just did this and got it wrong but saw the right answer which is this)
This is the concept of perimeter of geometric figures;
We are required to approximate the perimeter of the triangle given if JA=10, AL=23, CK=9
Summing the above measures we get;
10+23+9=42
assuming that this is half the perimeter of the whole triangle then;
perimeter=2*42=84
The answer is A
