A would be the answer because you -7of both sides then it would leave 4x=16 so then divided both sides by 4 so x=4

A knife is three times the cost of a spoon. 9 spoons and 12 knifes cost ?82.80 workout the cost of 1 knife.
tankabanditka [31]

Let S = spoon

Let K = knife


1 knife is thee times the cost of a spoon, so it would be 3S

Now you have 9S + 12K = 82.80

We can replace the K with 3S:

9S +12(3S) = 82.80

Simplify the left side:

9S + 36S = 82.80

Add:

45S = 82.80

Divide both sides by 45"

S = 82.80 / 45

S = 1.84

One spoon cost $1.84


We know one knife cost 3 times as much, so multiply the cost of a spoon by 3:

Knife = 1.84 x 3 = $5.52

Answer:

The concentration of hydrogen ions in moles per liter (M) is 3.981 * 10^{-9}

Step-by-step explanation:

As we know

The hydrogen ion concentration of any solution at pH is given by

H^+ = 10^{-pH}

Substituting the given values in above equation, we get -

H^+ = 10^{-8.4}\\H^+ = 3.981 * 10^{-9} mol/l

The concentration of hydrogen ions in moles per liter (M) is 3.981 * 10^{-9}
