Answer:
x = 42.67
Step-by-step explanation:
Harmonic mean between two positive numbers x and y, The simplified formula is 
I.e. you need to double the product of x and y then divide it by the sum of x and y...~
Use the point-slope formula
y-y1=m(x-x1)
y-1=-3(x-1)
y-1=-3x+3
y=-3x+4
1/50? I can’t be sure....
Ok, so.. first you write both the problems down and write the 10 as a fraction (so it would automatically be 10/1). Then invert so it would be a multiplication problem (1/5 x 1/10). Since you can’t cross cancel, you multiply across. So, 1/5 x 1/10 (1 x 1 and 10 x 5)
1/50
