Answer:
12 CDs and 15 DVDs
Step-by-step explanation:
Let
x----> the number of CDs
y---> the number of DVDs
we know that
x+y=27 -----> x=27-y ----> equation A
15x+19y=465 ----> equation B
Solve by substitution
substitute equation A in equation B and solve for y
15(27-y)+19y=465
405-15y+19y=465
4y=465-405
4y=60
y=15 DVDs
Find the value of x
x=27-y
x=27-15=12 CDs
That answer would be 28 because 8 + 0= 8 and there is no number to add with the 2 so it stays the same making the 28
Answer:10+5=15 8+8= 16. 15+16=31
Step-by-step explanation:
31
8 i believe hope it helps!
