Answer:
80g
Step-by-step explanation:
Here's why:
SO you have 2:3 ratio which means the ratio for grams of butter/grams of flour has to be 2:3.
So we set up the following equation:
2/3 = 640/x (solve for x)
x= 960g
960g is what you should have to get to ratio, but the question is asking how much more you need from the initial given flour.
So you need (suppose x is the grams of flour you need)
x+880g = 960g (solve for x)
x=80g
Answer:
175/3 or 58.333...
Step-by-step explanation:
This is fairly complicated but I will try to make it as simple as possible. I also apologize in advance for how impossible it is to make fractions look like fractions. I also had to insert a bunch of unnecessary parentheses just because the fractions that I can make are relatively inaccurate.
The distance between 2 cities can be represented as d.
Time is d/r if r is rate, so B->NY=d/50
Similarly,NY->B is d/70
Obviously the average speed is 2d/(d/50+d/70), this is just an average time
Now just remove the d and get (d/d)*2/(1/50+1/70)
You can now multiply by the LCM/LCM, which is 350/350.
After calculating you will get 700/12 which is 58.333...(This is how to enter into your RSM browser) Hope this helps. Sorry it is so late.
<u><em>Answer:</em></u>
a. The point (4,9) appears in both tables
<u><em>Explanation:</em></u>
<u>Note:</u> This question can be solved without the need of the tables
<u>A solution of a system of equations</u> is defined as a point (or set of points) that satisfy both equations
<u>This means that,</u> this point should belong to all the equations in the system
Now, a table is used to show a set of points that belong to a certain line
This means that, all vales in the table belong to the line they represent
<u>Since the point (4,9) appears in both tables</u>, therefore, it belongs to both lines and, therefore, is a solution to the system of equations consisting of these two lines
Hope this helps :)
