Can some one me set up an equation out of these word problems? ! 1: sam is an accountant. he finds that he spends two-fifths of his work day answering emails. if he spent 3.6 hours answering emails yesterday ,how many hours did he work.2: elaina charged $83 on her credit card to buy groceries. if the balance is now $294, what was the balance before she bought groceries.3: max spends three times as long on his math homework than he does on his science homework. if he spent a total of 64 minutes on math and science homework last night, how long did he spend on math homework.4 the gardenview hotel is seventeen less than twice the height of the plaza hotel .if their combined height is 361 feet, how tall is the gardenview hotel

1 He spent 9 hours working

2.  Her balance before she bought groceries is 83 + 294 = $ 377

3.He spent 16 × 3 = 48 minutes on his math homework.

4. Garden view hotel is 235  in height

Step-by-step explanation:

1. Sam spent 2/5 of his work day answering mail.  He spent 3.6 hours answering email yesterday  . To calculate how many hours he work let make the hours he worked yesterday = a

time he spent answering email  

2/5 × a = 3.6

cross multiply

3.6 × 5 = 2a

18  = 2a

divide both sides by 2

a = 18/2

a = 9 hours

2. Elena was charged $ 83 from her credit card to buy groceries. Her final balance after buying groceries was $ 294.  Her balance before she bought groceries is 83 + 294 = $ 377

3. Let say he spent a minutes long on science homework.

Time he spent on math homework = 3a

He spent a total of 64 minutes on math and sciences

3a + a = 64

4a =64

a = 64/4

a = 16

He spent 16 × 3 = 48 minutes on his math homework.

4.Let the plaza hotel height  = a

garden view hotel height = b

2a - b = 17(i)

a + b = 361(ii)

b = 361 - a

2a - (361 - a) = 17

2a - 361 + a = 17

3a = 17 + 361

3a = 378

divide both sides by 3

a = 378/3

a = 126

insertthe value of a in equation (ii)

a + b = 361(ii)

126 + b = 361

b = 361 -126

b = 235
