Question

Can some one help me set up an equation out of these word problems? PLEASE HELP!!!

Answer 1

Answer:

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

Answer 2

1: 2/5=emails 3.6hrs=emails, 3.6=2/5 5-2=3 3.6•3=__hours of work

2. 294+83=$__

3. 3•x=hw 64/4=__•3=__hrs on math

4. Idk sorry


Sorry if some of these are wrong but I'm pretty sure there right.
