Two numbers have a sum of 42. the larger number is 6 more than the smaller. find the nunbers

x + y = 42

y=6x

x + 6x = 42

7x = 42

x=6

y = 6 x 6 = 36

numbers are 36 & 6

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

1332.

this is because to get from 333 to 999 you multiply by 3, and you should do the same to the number of hours.

therefore you would do 444*3=1332
