Question

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?

Answer 1

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.
