Answer:
Percent error is approx. 22%
Step-by-step explanation:
So to do this you need to know the formula for percent error, which is
percent error = l measured - theoretical / theoretical l * 100%
With this just plug in 18 (real) and 14 (measured).
percent error = l 14 - 18 / 18 l * 100%
percent error = l -4 / 18 l *100%
percent error = l -2/9 l *100%
You then do absolute value because the percent error must be positive not negative! So -2/9 becomes 2/9. You then divide 2/9 to get approx. 0.22... and you muliply by 100% to get 22%.

Second table: 3x+2=y
Step-by-step explanation:
It was really just testing it out, checking to see if an equation worked for one row, then try in the next. Its hard to explain, but its really just guess and check ;D
I hope this helps!

Step-by-step explanation:
Hello
let's assume that we are looking for x >=0
Let's assume that we are looking for x>=0
so the correct answer is 5
X = -6
y= -34

Multiplying decimals is basically the same thing as multiplying whole numbers, but a little tougher. For example, 3 X 2 = 6, which is quite easy, but yoou might need more education to solve 3.6 X 2.6 = 9.36
