Answer:

I believe that the correct answer is 57.5.

Step-by-step explanation:

If you do the problem straight up the answer will be 20, but if you use order of operations (or PEMDAS) the answer will be 57.5.

Answer: 57.5

Step-by-step explanation: The first thing you need to know about the order of operations is that multiplication and division come before addition and subtraction.

So in this problem, we are going to divide before we add.

Since 30 divided by 4 is 7.5, our next step will read 50 + 7.5 and 50 + 7.5 simplifies to 14.

There is a proportional relationship between your distance from a thunderstorm and the time from when you see the lightning and
eimsori [14]

Answer:

Yes.

Step-by-step explanation:

The relation would be 3 = k*9  as there is a direct proportional relationship.

So k = 3/9 = 1/3  and we can write the relation as d = 1/3 t   where d=distance and t = time.

So if we double the time t we have:-

d = 1/3 * 18

= 6 kilometers.

So the distance is doubled.

The perimeter of a rectangle is 44 inches. If the length is 1 more than twice the width, what is the length and width?
Jlenok [28]

Answer:

The width is 7 inches, the length is 15 inches

Step-by-step explanation:

If the width is x inches, then the length is 2x+1 inches. Since the perimeter of a rectangle is 2 times the width plus 2 times the length, the perimeter will be 2x+2(2x+1), which simplifies to 6x+2. Since the perimeter is 44 inches, we get the equation 6x+2=44, which makes x=7. So, the width is 7 and the length is 15.
