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
4/52
then u would divide both numbers by 4 and get
1/13

Answer:
x^8 * y^3
Step-by-step explanation:
Square both sides to get (x^10 * y^4)/(x^2 * y). Divide both sides by x^2 to get (x^8 * y^4)/y. Divide both sides by y to get x^8 * y^3.
