Step-by-step explanation:
u should:
7t = t + 48 » 7t - t = 48 » 6t = 48 » t = 8
and another one is:
2u + t + 13 = 10t + u - 44» 2u + 8 + 13 = 80 + u - 44»
» 2u + 21 = u + 36 » 2u - u = 36 - 21 » u = 15
1/14 in 30 mins
30 mins x 14=420 mins
420 mins in hours =7 hours
I'm pretty sure it's graph A. I apologize if it's wrong hope this helped.
It's diameter is 17.98. (I'm pretty sure I'm right I even used a calculator, if not sorry)
In order to find the slope of line that passes through 2 points, use the equation slope=rise/run
rise = 5-(-4) =9
run = 2- 0 =2
slope = rise/run = 9/2
