0.578 rounded to the nearest tenth would be 0.6, since the 7 in the hundredths spot is higher than 5.
Pls mark me brainiless
(4/5)(x - 2) = 18
4(x - 2) = 90
4x = 98
x = 24 1/2
Hmm, one way is this
there's 500 times 0.10 or 50 grams of salt in the water
if we want to make 50 grams=4% of everything, how much water do we need to add
50=4% of all
50=0.04 of all
divide both sides by 0.04
1250=all
so
500+what=1250
minus 500 both sides
what=750
750 grams of water
