Step-by-step explanation:
65=(4x+1)
65=4x+1)
65-1=4x
64=4x
64/4=4x/4
x=16
Answer: + + + 2
Step-by-step explanation:
f(x) = - 4x + 2
g(x) = + 2
To find fg(x) , we have
fg(x) = f( + 2 )
The next thing is that , we will substitute + 2 for the value of x in f(x) , so we have:
- 4( + 2) + 2
which will give
+ + + 2
Therefore :
fg(x) = + + + 2
Answer:
5 groups
2 extra children
Step-by-step explanation:
The computation of a number of groups and number of extra children is shown below:
Given that
There is 27 children
And, this group would be divided into group 5
So,
As we know that 25 is easily divided by 5
So there are 5 groups
And, the extra children is
= 27 - 25
= 2 chidren
A.43 72-12=60+3=63-20=43
20 came from temperature dropping 2 degrees every 30 minutes for 5 hours means that it dropped a total of 10 times, and 10x2=20 so the answer is 43
