From this question I take it that you need to know what is 130% of 45 mg. 130% of 45 is equal to 1.3x45, which is 58.3. So, your answer is 58.3 mg of the vitamin.
Answer: y= -2 - 1/2
Step-by-step explanation:
-4x -2y = 1
+4x +4x
-2y = 4x + 1
/-2 /-2 /-2
y= -2 - 1/2
I think, i may be incorrect but the verbal explanation is; -4x is needed to be moved so you add 4x to both sides and 4x cancels out on the left which leaves -2y on the left (when it was moved "x" is always first). then divide all numbers by -2 to get y by itself. this gives you y= -2 - 1/2 if my calculations are correct.
89 divided by 7 + 46^2 = 2128.71428571...

Step-by-step explanation:
Take John's sister's age as "x"

And 5 years more, means = 2x + 5
So finally John's age = 2x + 5
