What is the sum of 12 and the quantity 8 times a number k is equal to 48? It was on my math homework, it hardly makes any sence to me, please help me, whats the answer?
For this question you are looking for the value of K. The question is asking what number multiplied with 8 and added with 12 equals 48. So the equation is:
12+8(K)=48
To solve the problem you need to balance the equation by doing the opposite of the equation to the answer until only K remains.
We start with the 12. The equation wants us to add 12 so we subtract it from both sides instead and get the new equation:
12+8(K)=48-12 : 8(K)=36
Now we need to get rid of the 8. The equation wants us to multiply by 8 so we divide it from both sides instead and get the new equation:
K=36/8 : K=4.5
So the answer is K=4.5. Now just to make sure we test the equation with the answer.
12+(8x4.5)=48
12+36=48
48=48
Since the two match we have confirmed that K does indeed equal 4.5.
