What are the measurements for DBC, ABD, and ABC please. Best answer gets brainliest

DBC = 79

ABD = 31

ABC = 110

Step-by-step explanation:

DBC + ABD = ABC

4x + 19 + 2x + 1 = 8x - 10

6x + 20 = 8x - 10

-6x            -6x

20 = 2x - 10

+10         +10

30 = 2x

 2      2

x = 15

DBC = 4x + 19

DBC = 4(15) + 19

DBC = 79

ABD = 2x + 1

ABD = 2(15) + 1

ABD = 30 + 1

ABD = 31

ABC = 8x - 10

ABC = 8(15) - 10

ABC = 120 - 10

ABC = 110

 OR

DBC + ABD = ABC

79 + 31 = ABC

110 = ABC

$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)
