Answer 1

1. D:9=50

D=50.9

D=450

2. 81=3X

81:3=X

X=27

3. 500:r=25

500:25=r

r=20

4. 124 = 4h

124:4=h

31=h

5- 4 + k = 32

k=32-4

k=28

6- 66-b = 42

-b=42-66

-b=-24

b=24

7- h + 120 = 135

h=135-120

h= 15

8- 8y = 200

y=200:8

y=25

9 - 2f = 46

f=46:2

f= 23

10- m - 28 = 72

m=72+28

m=100

11 - 25p = 1000

p=1000:25

p=40

12- m + 12 = 60

m=60-12

m=48

13- 100-n = 45

-n=45-100

-n=-55

n=55

14- c + 13 = 51

c=51-13

c=38

15- 24 + a = 36

a=36-24

a=12

16- c+9 = 10

c=10-9

c=1

17- 2b = 16

b=16:2

b=8

18- k : 6 = 15

k=15.6

k=90

19- e : 4 = 25

e=25.4

e=100
