The answer is b. There is a picture of the graphed function: y=3(1/2)^x
2x+9+8x+1=180
2x+8x+9+1=180
10x+10=180
10x=170
X=17
2/3 × 42 = 28 × = 280 is ur answer
5:8
is the ratio .he she and shd
What you need to do is divide 32 by 40 so you end up with 1%. Then you need to multiply that by 25 and you will get 25%
32÷40=0.8
0.8x25=20
