So if you let x and y be the two numbers...
the sum of the two means you add them together... so you get:
x+y=56 : the difference means you subtract them.. so
x-y = 16
now you have two equations and two unknowns... which you can solve with a variety of methods... you can use elimination, substitution, or trial and error.
x+y=56
x-y = 16
I will use the elimination method: Because there is a plus y and a negative you cancel that out and you add the 2x's. Therefore:
2x=72
x=36
Now, you can plug in 36 into one of your original equation:
36+y=56
y=20
Those are your two numbers!
Answer:
no
Step-by-step explanation:
because the number of student tickets 160 is higher than the number of adult tickets 80 and the information tells us that the adult tickets were twice the amount of student tickets sold. If the numbers were swapped to be adult=160 and student=80 then it would be correct.
sorry for the long explanation especially if you find it confusing
2/52 or 3.846% chance
this is because there are 2 possible black aces to choose from and the other 2 are red.
2 minutes.
EXPLANATION:
To find the answer, we can find an equivalent fraction for each.
1/6 x 6 = 6/6
1/12 x 6 = 6/12
So every 1 minute Loki writes half a page.
Since 2 halves = 1.
2 minutes for 1 page.
Hope this helps!
