Answer:
I believe the answer is c.) x=4
Step-by-step explanation:
I saw this on a webpage:
The moment we see “x,” we can consider picking numbers. The key here is contemplating how complicated the number should be. Swim with the current – let the question tell you. A quick look at the answer choices reveals that x could be something simple. Ultimately, we’re just dividing this value by 2, 3, 4, 5, or 6.
Keeping this in mind, let’s think about the first line of the question. If there are 3 times as many adults as children, and we’re keeping things simple, we can say that there are 3 adults and 1 child, for a total of 4 people. So, x = 4.
Now, we know that among our 3 adults, there are twice as many women as men. So let’s say there are 2 women and 1 man. Easy enough. In sum, we have 2 women, 1 man, and 1 child at this picnic, and a total of 4 people. The question is how many men are there? There’s just 1! So now we plug x = 4 into the answers and keep going until we find x = 1. Clearly x/4 will work, so C is our answer. The key was to let the question dictate our approach rather than trying to impose an approach on the question.
If there are 500 mg of medicine in 5 ml of liquid, we need to set up a proportion to find out how much liquid medication has 125 mg of medicine in it. Set up the proportion as follows:
.
Cross multiply to get 500x = 625. Divide by 500 to get that you need 1.25 ml of liquid if your dose is 125 mg of medicine.
