I think that the most accurate one is trial 3 since it is the least incorrect and closest percent-wise to the actual correct density of the metal.
Hope this helps!
Step-by-step explanation:
let father's age be f yr old and son age be s yr old
f = 5s -(1)
f + s = 60 -(2)
sub (1) into (2):
5s + s = 60
6s = 60
s = 10
f = 60 - 10 = 50
in 5 yr time, father age = 50 + 5 = 55
son age = 10 + 5 = 15
Answer:
<u>x = 5</u>
Step-by-step explanation:
Equating the terms :
Add 2 on both sides :
- x + 3 + 2 = 2x - 2 + 2
- x + 5 = 2x
Subtract x from both sides :
- x + 5 - x = 2x - x
- <u>x = 5</u>
Answer:
3.025 x 10³ sq ft
Step-by-step explanation:
Answer:
a) Find the value of the function when x = -2
b) we get f(-2)=65
Step-by-step explanation:
We are given the function f(x)=6(8-x)+5
a) What does the notation f(-2) mean?
The notation f(-2) means that we have to put x = -2 in the given function of f(x) and find the value of the function when x = -2
b) What is the value of f(-2) ?
We need to find the value of f(-2)
Put x = -2
So, we get f(-2)=65
