Answer:
Not true
Step-by-step explanation:
x + (2x + 5) = 3(x – 4)+7
Opening bracket on left and side and distributing 3 over (x-4) on right hand side
x+2x+5=3x-3 x 4 + 7
adding like terms
3x+5=3x-12+7
3x+5=3x-5
Hence
5 = -5
Which is not possible , Hence the equation given to us is false.
The conclusion is valid
it is a systematic random sample
and the second one is a line graph (I think)
18/7 or 2 4/7 bc 3/7 times 6 is 18/7 or 2 and 4/7
