First let's define variables:
r: reading
s: skimming
We write the system of equations that adapts to the problem:
r + s = 275
(15/10) r + (10/15) s = 355
We solve the system of equations:
r = 206
s = 69
Note: see attached image for system solution.
Answer:
Jayden had to skim 69 pages through
I agree with the answer being B because since it's a common ratio you could just multiply -1/4 with -2 and keep doing that with each new term
Answer:
5
Step-by-step explanation:
because ?*9=45
45÷9=5
4/3 is your answer because if you simplify 8/6 by dividing both the numerator and the denominator by 2, you will get 4/3.
Also, if you want a mixed number, it is 1 1/3.
Hope this helps!
31.75 as an improper fraction is 127/4. The mixed number fraction is 31 3/4.
