Step-by-step explanation:

1) 16/25=64/100=0.64

2)3/4=75/100=0.75

3)55/100= 11/20

4)80/100=4/5

5)850/100= 8.5

6) 245=70x→x=3.5

7)·3²·5=720

8)2·2·2·5·5=200

9) 36= 9·4=3·3·2·2

10)100=10·10=5·2·5·2

11) 3+5x=23→5x=20→x=4

12)x+19<22→x<3

13)2x-6=9→2x=15→x=7.5

14)x+3>6→x>3

15)12x=480→x=40

16)x+24=60→x=36

17)114.50=8.50x→17=x

18)25/100=2/8, 33 1/3= 2/5, 40/100=4/10, 20/100=2/10

19)9%= 9/100, 1/12=8.3/100, 17%=17/100, 1/25=4/100

20)x-32>17→x>49

21)9x<45→x<5

22)0.08k<28→k<350

23)55/100=11/20=0.55=55%

24)25/50=1/2=0.50=50%

25)15/4=375/100=3.7, 3 1/7=22/7=314.29/100=3.14,

step-by-step explanation:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
