This is the same as 9 x 10^4 = 90000 in this case 'e' means 'exponent'
75 m/hr x 5280 ft/m x 1hr/3600 sec = 110 ft/sec
30/24 = ( 24 + 6 )/24 = 1 6/24 = 1 3/12 = 1 1/4
Absolutely nothing we can do with this without a leeeeeeetle more information......do you have some more of the equation?
A 2200 m/hr x 2 hr = 4400 miles
I think you can do the other two....pretty straightforward....
-20000 + 18800 = -1200
-1200/(10^6) = -1200 x 10^(-6) = -1.2 x 10 ^(-3)

4 38 12
- 2 42 23
= 1 55 49
Yes it is linear... it is y = mx + 0 0 is the y axis intercept (just sub in x=0 to find the y intercept in line equations)
1 /4 x = 1/4 of a number x
1/4 x -7 = - 1 Add 7 to both facts
1/4 x = 6 Multiply both sides by 4
x = 24
