Procedure:
If you have a fraction turn it into a decimal by doing this:
6/10= 0.6
this works because the 6 is in the tenths place and it is 6/10 as a fraction.
It works with thousandths and hundreths:
4/100=0.04
9/1000=0.009
This works with even bigger place values.
Answer:
Initial charge is $2.5
Hourly charge is $3.5/hr
Equation is y=3.5x+2.5
Step-by-step explanation:
Getting slope
Get fixed charge
Get equation
The slope can be found as follows. For 1 hour, charges is $6 so making time in x axis while money charged in y axis, the first coordinate is (1, 6) while for 4 hours with charge of $16.5 the coordinate will be (4, 16.5)
The slope will be given by dividing change in y axis to change in x axis. This will be (16.5-6)/(4-1)=3.5
To get the fixed charge
Using the equation y=mx+c where m is slope while c is fixed charge, x is time and y is total cost then for 1 hour
6=3.5(1)+c
C=6-3.5=2.5
Therefore, generally the equation will be y=3.5x+2.5
Initial charge is $2.5
Hourly charge is $3.5/hr
Equation is y=3.5x+2.5
The value of the expression is 8. I hope this helps!!!
(6t-n)2
6x (2)-n(2)
6 *2t-n (2)
12t-n(2)
12x-2y is your answer,good luck!
