Let h = the $ Hope makes
Let t = the $ Tristan makes
a. h + t = 345
h = 35 + t
b. (35 + t) + t = 345
35 + 2t = 345
2t = 345 - 35
2t / 2 = 310 / 2
t = 155
h = (155) + 35
h = 190
c. graph above ^^ the point where they cross is the answer to the problem
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
