3 reds in the 10 remaining cards
so that is 30% are red
Answer:
There are 23 dimes in the box
Step-by-step explanation:
Let nickels=n
Let dimes=(35-n)
Equation: 0.05n+0.10(35-n)=2.90
Multiply both sides by 100: 5n+10(35-n)=290
-5n+350=290
-5n=-60
n=12
35-12=23
Therefore, there are 23 dimes in the box
can you make the pic little more clear if you can :)
I’m not 100% sure but isn’t it x2 +xy +y2?
