a =55

b =16

c = 25

d = 9

Step-by-step explanation:

of means multiply  is means equals

20% of a is 11

.20 a = 11

Divide by .20

a = 11/.20

a=55

75% of b is 12

.75 b =12

Divide by .75

b = 12/.75

b = 16

80% of c  is 20

.80 c =20

Divide by .80

c = 20/.80

c =25

200% of d is 18

2.00 d = 18

Divide by 2.0

d = 18/2

d =9

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
