Answer:
x = ± 
Step-by-step explanation:
Given
x² = 20 ( take the square root of both sides )
x = ±
which can be simplified to
x = ± 2
[ ± means plus or minus ]
3x + 11.63 = 20
3x + 11.63 - 11.63 = 20 - 11.63
3x = 8.37
by subtracting the 11.63 from both sides, this tells us how much the grapes cost....not per lb., but for the total of all the grapes.
No, 3/4 is equivalent to 6/8 and 7/8 is in its final form
Answer:
To know what is the average of it
Step-by-step explanation:
Hey!
-------------------------------------------------
This just shows to substitute all of x with -1.
g(-1) = 3(-1) - 5
g(-1) = -3 - 5
g(-1) = -8
-------------------------------------------------
Hence, the answer is -8!
