2 answers:

7 0

4(2r - 1) = -2(3r + 16)...distribute thru the parenthesis
8r - 4 = -6r - 32
8r + 6r = -32 + 4
14r = - 28
r = -28/14
r = -2 <===

4 (2r-1) = - 2 (3r + 16)
Distribute 4 and 2 in brackets

8r-4 = -6r-32
8r+6r = -32+4
14r = -28
r = -28/14
r = -2

A block of ice melts 8oz every 5 minutes it began melting at 8:00am weighing 250 pounds at what specific time will it be complet

dimulka [17.4K]

Answer:

1:40 am the next day

Step-by-step explanation:

1 pound = 16 oz

The block of ice melts 1 pound or 16 oz in 10 minutes

10 x 250 = 2,500

It will take 2,500 minutes to melt completely.

2,500 divided by 60 = 41.66666 or 41 hours and 40 minutes

60 minutes = 1 hour

1 day = 24 hours 41.6666666 - 24 = 17.6666666

8 am + 17 hours and 40 minutes = 1:40 am the next day
