Answer:
45
Step-by-step explanation:
These work problems are always done in terms of fractions ie if both (Kevin & Eric) took 30mins to mow and Kevin took 1.5hrs (90mins) alone then we can make an equation like below
1/time took for both = 1/time took for Kevin + 1/time took for Eric
1/30 = 1/90+1/x ==> calling time took for Kevin x
solving the above 1/x = 1/30-1/90
1/x=2/90
x=45
Answer:
Step-by-step explanation:
if we are supposed to solve + 2x + 9 = 0 there here is the solution
using the quadratic formula
= (-2 ± )/2
= (-2 ± ) / 2
= (-2 ± i )/2
= (-2 ± i 4)/2
= -1 ± i 2
