Answer:
12 games
Step-by-step explanation:
Let x be the number of games played
The y won 75% of the games played and that was 9
x * 75% = 9
Change to decimal form
x * .75 = 9
Divide each side by .75
x * .75 /.75 = 9/.75
x =12
They played 12 games
Answer:
2.57 cm
Step-by-step explanation:
sides of full frame with photo:
2x+16 and 2x+10
Area A= (2x+16)(2x+10)
Area of photo alone P= 16*10
As per question: A=2P
- (2x+16)(2x+10)= 2*16*10
- 4(x+8)(x+5)=2*2*8*10
- x²+13x+40=80
- x²+13x-40=0
- solving this we get x= 2.57 cm
