Answer:
A. 2x+4y=20 B. x+6y=10 C. 3x+3y=13 D. 4x+2y=20
Answer:
2 and 8
Step-by-step explanation:
Larger number = y
Smaller number = x
---------------------------------
y = 2x+4
y - x = 6 -> y= x+6
---------------------------------------
x + 6 = 2x + 4
2 = x
y = x+ 6
y = 2 + 6
y = 8
Hope this makes sense!!!!
Answer:
see below
Step-by-step explanation:
If x represents the number of dimes, then 2x will represent twice the number of dimes. This is the number of quarters, since there are twice as many quarters as dimes.
There are 6 more nickels than dimes, so the number of nickels is 6 more than x. It is (x+6).
If we use the monetary values in cents, then the total of all coins is ...
25(2x) +10(x) + 5(x+6) = 485 . . . . . . matches choice D
