Do you need help solving the sequence?
The equation to calculate percent error is # experimental - #theoretical / # theoretical * 100. The experimental value is 24 and the theoretical value is 42. Here's the calculation 24-42/42 * 100 = -42.86 rounded. Hope this helped :))
Answer:
x=2.5
Step-by-step explanation:
the first thing you want to do is simplify like terms.
you could say this is as 4(x+7)=38
this can easily be solved algebraically.
first use distributive property on the four
this leaves you with 4x+28=38
next, subtract 28 from both sides
4x=10
now divide everything by four and you get x=2.5
You multiply .65 times 100 and you get 65 which is 65% of 100
