Answer:
it is option 3
Step-by-step explanation:
-4(5p+3)
by opening brackets, you get
-20p -12
It is actually the top one on the second picture because if you were to rotate it 180 degrees, it would end up on the same points
I believe you would need to divide 123.75 by 7.50.
The equation would look something like this:
7.50x=123.75
Where x = # of hours worked
123.75 / 7.50 = 16.5
so x = 16.5
You worked for 16.5 hours
Answer:scales percent error=3.51%
Step-by-step explanation:
P ercent error = Experimental value - Theoretical value /Theoretical value x 100
Theoretical value = 6255 grams
Experimental value ( use of scale ) = 6475grams
Percent error =(6475- 6255)grams / 6255grams x 100
=220/6255 x 100
=3.51%
24)y=x-4
21) y=-3x+1
23) y=4/5x+6
