Answer:
1 and 7/12 hours
Step-by-step explanation:
2 and 1/3 is the whole. You need to subtract 3/4. To bring both of these to the same denominator, multiply each fraction by the others denominator. That means 1/3 is now 4/12 and 3/4 is now 9/12. They can now be subtracted. 2 and 4/12 - 9/12 = 1 and 7/12.
Answer:
418/3 sec
Step-by-step explanation:
We know it can crawl 6 cm in 22 sec, so we set up a proportion:
, where x is the time for the bug to crawl 38 cm
Cross multiplying, we get: 6x = 22 * 38 = 836; so, x = 836/6 = 418/3 sec
Thus, the answer is 418/3 seconds.
Hope this helps!

The equation becomes,
Answer:
C
Expand the bracets then simplfy and then factorise
Answer:
C
Step-by-step explanation:
we have to solve the associated equation:
(x+5)(2x-8) = 0
a product is equal to 0 if at least one of its factors is equal to 0
so we can solve this two equations
x + 5 = 0 x = -5
2x - 8 = 0. x-4 = 0 x = 4
