Section 1:
using this format we can determine what the answer is:
42 105
—— • ——-
100 x
(the spacing may be off but imagine two separate fractions)
first multiply 100 by 105 to get 10,500
then divide by 42 to get 250
this means that sasha’s book has 250 pages
section b:
using the same formula we can solve this problem:
first we need to multiply 250 by 2 to get the total cost of both tickets
175 x
—— • ——
100 500
(again spacing may be off but think of two separate fractions)
then multiply 500 by 175 to get 87,500
then divide by 100 to get 875
to find the profit subtract 875-500
this means he will make $375 profit
conclusion:
sasha’s book has 250 pages
trevor will make $375 profit
this is the method my teacher taught me last year so it should be right, hope this helps and please mark brainliest!!
In general, when you state "the difference between a point A and a point B" meaning that you have to take the final value at the point B subtract the initial value at the point A"
<span>For example: Find the difference in distance between a point A =2 m and a point B = 5 m? </span>
<span>In this case: </span>
<span>In general: The difference in distance = 5 m - 2 m = 3 m </span>
<span>You can also write it as: </span>
<span>The difference in distance = 2 m - 5 m = -3 m </span>
<span>Since the distance between 2 points CAN'T be a negative value, you've to take the absolute value of -3 m to get the positive answer of 3 m. </span>
<span>This based on a scalar quantity. </span>
<span>Unless you're working on a Vector problem in Physics. In this case, you must take the final point subtract the initial point since the motion not only describes the magnitude but also describes the direction of the motion as well. </span>
<span>Again, in this case, you can have the magnitude is always a POSITIVE number and the direction can be either POSITIVE or NEGATIVE depends on the direction that you chose as a positive. </span>
<span>Back to your question. "the difference between 15 and the product of 5 and y" </span>
<span>I would write this statement as 5y - 15 </span>
Answer:
The answer would be 2 1/4 days
Step-by-step explanation:
Take 54 and divide it by 24 (since there are 24 hours in a day):
54 / 24 = 2.25 or 2 1/4
Hope this helps! If so, please mark brainliest!! :)
2y=10+5x
y=2x+5 so there ya have it i need 20 characters
