Answer: 348 and 355
Step-by-step explanation:
Let two positive numbers are x and y
so,
when the difference is 7 then equation will become
x-y=7 Eq(1)
when product is 2439 then equation will become
x*y=2438 Eq (2)
By rearranging Equation (2)
x= 2438/y Eq(3)
Now put the value of x as in eq (3) in eq(1) to get y's value
(2438/y)-y=7
(2438-1)/y =7
2437 / y =7
2437/7 =y
y=348.14 approx 348
Put the value of y in Eq(1) for x
x-348=7
x=7+348
x=355
so the two positve numbers are 355 and 348
For Check
x-y=7
355-348=7
7=7
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!
