Answer:
t = 8.9
Step-by-step explanation:
6.35t = 56.515
56.515 / 6.35 = t
t = 8.9
What is being solved for is r.
heather can do 2 problems in 10 minutes....60 minutes in an hr
2/10 = x / 60...2 problems to 10 min = x problems to 60 min
10x = 120
x = 120/10
x = 12....so she can do 12 problems in 1 hr
Joel can complete 3 problems in 15 minutes...
3/15 = x / 60
15x = 180
x = 180/15
x = 12....so he can do 12 problems in 1 hr
so 24 problems can be done in 1 hr
Heather started with 3 problems done and Joel started with 2 problems done....added = 5 problems already done
and it is asking between 30 and 50 hrs.....so there is no equal sign in ur problem
ur answer is : 30 < 24x + 5 < 50 <==
I'd definitely factor 4x^2-48 first. Factors are (4)(x^2-12).
This factors further: (4)* (x-2sqrt(3) ) * (x+2sqrt(3) )
