B is the answer hope that help
1 1/9
To figure out how much walnuts to a pound of dried fruit you’d need to do proportions. So we cross multiply:
2/3 = X
—————- —————-
3/5 = 1
You multiply diagnols 2/3 x 1 = 2/3
3/5 times x is 3/5x.
2/3 = 3/5x. Isolate the variable. Divide 3/5 on both sides cancel out 3/5. 2/3 divide by 3/5 is 2/3 x 5/3 which is 10/9 which equals 1 1/9.
So for 1 lb of dried fruit you need 1 1/9 lb of walnuts to maintain the same mixture
Percent change formula states that
((New-old)/old) x 100 = the percent change / percent increase
So if we take your equation and plug it into our formula
((225-120)/120) x 100
(105)/120 x 100
.875 x 100
87.5 % increase of students on the trip
Hope this helps!
Answer:
10% is equivalent to the unit fraction 23
To find 10% of 230, multiply 230 by 0.10
10% of 230 is 23
Think about it, if 100% of 230 is 230, and 10% is 23, you can multiply 23 x 100 to get 230. I took a while to answer, but I hope my explanation helps.
we have
--------> equation
--------> equation
Multiply equation by both sides
------->
the two equations of the system are the same, both equations represent the same line
so
If a consistent dependent system that has an infinite number of solutions
therefore
<u>the answer is</u>
The system has infinite number of solutions
