Answer:

c=2.22

Step-by-step explanation:

1/a- 1/b=1/c- 1/d

1/1/2- 1/1/4=1/c- 1/1/5

0.5-0.25=1/c- 0.2

0.25=1/c- 0.2

0.25+0.2=1/c

0.45=1/c

cross multiply

0.45×c=1

0.45c=1

divide both sides by 0.45

0.45c=1/0.45

c=2.22

A light bulb consumes 960 watt-hours per day. How many watt-hours does it consumes in 4 days and 18 hours?
MaRussiya [10]
960 watts = 24 hours

4 days = 96 hours

960 (watts) x 4 (days) = 3840 watts

12 hours= 480 watts

6 hours = 240 watts

18 hours = 720 watts

3840 (4 days) + 720 (18 hrs) = 4560

4 times a number less than 6 is 8 more than twice that number. find the number.
Serhud [2]
First, let's break the worded equation up into two parts:

- "<span>4 times a number less than 6'

This is 4 * (6-x)

- "</span><span>8 more than twice that number"

This is 2x+8


Now combine these two expressions:

</span>4 * (6-x) =  2x+8

4 * (6-x) = 2 * (x+4) 

2 * (6-x) = x+4

12-2x = x+4

-3x = -8

x = 8/3


If you have any questions, please leave it in the comment section below.

Hope this helps!
