Answer:
equation of the table is y=30x+60
60 degrees is what the temperature starts at
to get to 440 degrees he needs 12 minutes and 40 seconds
Step-by-step explanation:
the change in y over change in x is 90/3 which is the slope
slope is 30
if slope is 30 then 30*2+b=120 60+b=120 so b=60 and it is the y intercept
440=30x+60
380=30x
x=12 2/3
x= 12 minutes and 40 seconds
Answer:
The equation for that would be n+15=27
Step-by-step explanation:
We can use any variable to represent 'a number'.
W will add since the value is getting increased by n
n+15=27
If we wanted to solve this, we would subtract 15 from 27 to get 12=n
hope this helps :)
Answer:
The graph in the attached figure
The point (-1,4) represent a solution
Step-by-step explanation:
we have
----> inequality A
----> inequality B
using a graphing tool
The solution is the shaded area
see the attached figure
Remember that
If a ordered pair is a solution of the system of inequalities, then the ordered pair must lie on the shaded area of the solution of the system of inequalities
The point (-1,4) represent a solution
First we need to convert pt into qt
1qt = 2pt
That means that 50 pt is:
50/2 = 25 qt
And now we convert qt to L
25/1.06 = 23,6 L
Answer is A) 23,6 liters
