24. This is because when you multiply a negative times a negative you get a positive number. Meaning that the new equation would be 12×2
X = 12
27x - 45 = 18x + 63
-18x
9x - 45 = 63
+45
9x = 108
108/9
Answer:
27/14 or 1 13/14
Step-by-step explanation:
First you simplify the problem to 3/7 × 9/2. then you multiply them to get 27/14 or 1 13/14.
In geometry proofs, we commonly use step-by-step logic to figure out the proof. This is commonly used in Computer Science for understanding how computers work, process, and store information(I speak from personal experience). This is also commonly used in Law. You use this in Law as a lawyer to deduce information using step-by-step logical processes and logic, otherwise it's just wishful thinking. So, Law also uses the same reasoning skills used in Geometry proofs.
Yards= 42 2/3 yd=42 + 2/3 yd=(42*3 + 2)/3 yd=128/3 yd
Gallons=1 1/3 Gallons=1+1/3 gallons=(3*1+1)/3 gallons=4/3 gallons.
Rate=number of yards / number of gallons.
Rate=(128/3 yd) / (4/3 gallons)=32 yd/gallon.
Answer: Angela´s rate=32 yards / gallons
