Answer:
Ming must add 0.375 L of a 10% sugar solution
Step-by-step explanation:
if 3 L = 80%
1.5 L should = 40% (since it is half of 80%)
and if 40 divided by 4 = 10%
1.5 also needs to be divided by 4
so 1.5 divided by 4 = 0.375
that means Ming must add 0.375 L of a 10% sugar solution
Answer:
2cents
Step-by-step explanation:
40/20=2
<span>f(x) = 2x – 4
</span><span>inverse
x = 2y - 4
2y = x + 4
y = x/2 + 2
answer
inverse
f-1(x) = </span>x/2 + 2
