8p + 3q - 18 when p = 1/2 and q = 7
You are given that p is equal to 1/2 and q is equal to 7, so plug these values into p and q in the expression to find your answer.
Rewrite your expression to include the values of p and q plugged in. Your expression should look like:
8(1/2) + 3(7) - 18
According to PEMDAS, multiplication should be solved first before doing subtraction, so multiply 8 by 1/2 and 3 by 7. Rewrite your expression; your expression should look like this:
4 + 21 - 18
According to PEMDAS, addition and subtraction should be solved from left to right; they are not prioritized. So solve the expression from left to right and then you will have your answer.
4 + 21 = 25
25 - 18 = 7
Your answer is 7.

Below is the solution:
<span>distance = 475
</span>time = 9.5 hrs
<span>since distance and time varies directly
</span>
therefore in 9.5 hrs train travels 475 miles
=> In 1 hr train travels 475 / 9.5 miles = 50 miles
<span>and in 4 hrs train travells 50*4 i.e 200 miles </span>
Fractions and whole numbers ordered on the number line are similar because it tells parts throughout the line, like skip counting using adding or subtraction for example.
Whats different from them is because the fractions tell the parts more detailed between the whole numbers, such as 2 3/4 as a fraction on the number line. And 3 as a whole number on the number line.
