Help Please! Would Appreciate It

Answers

Answer 1

Answer:

yes

Step-by-step explanation:

just plug in

2+3 is equal to 5 so that works

4(2)+13(3) is greater than 20 so that also works

Answer 2

Answer:

Yes

Step-by-step explanation:

I can explain more in-depth if you'd like, but basically plug in 2 where x is and plug in 3 where y is. The first equation would turn into 2 + 3 ≤ 5, which is correct, and the second equation would transform to 4(2) + 13(3) > 20. Multiply, then it'll be 8 + 39 > 20, then add 8 and 39 and it'll be 47 > 20, which is true. I hope I explained that well, but yes, (2, 3) is a solution :)

At 11:45 A.M. Jason glanced at the clock. His doctor's appointment was in 2 ½ hours. At what time was his appointment

Answers

Answer:

14 : 15 or 2 : 15 pm

Step-by-step explanation:

Time of the appointment = 11: 45 +  2 ½ hours

Jason's appointment is in  2 ½ hours. His appointment is in 2 hours + 1/2 of an hour

1/2 of an hour = 1/2 x 60 = 30 minutes

Remember that 60 minutes make one hour

Time of the appointment = 11:45 + 2:30

 [tex]11 : 45[/tex]

+ 2 : 30

 13 :  75

we would have to adjust the time derived from the addition because the maximum minutes that exist is 60

To adjust, remove 60 minutes from the minutes and add it to the hour

this gives 14 : 15 or 2 : 15 pm

Na casa de Isabel, a leitura do hidrômetro, feita no dia 20 de março, indicava 2431 metros cúbicos. Uma nova leitura, feita um mês depois, indicou 2 590 metros cúbicos. Quantos metros cúbicos de água Isabel e seus familiares consumiram nesse período?

Answers

Answer:

159 metros cúbicos

Step-by-step explanation:

Os metros cúbicos de água que Isabel e sua família consumiram durante este período são calculados como:

Nova leitura - primeira leitura

Primeira leitura = 2.431 metros cúbicos

Nova leitura = 2590 metros cúbicos

Conseqüentemente:

2.590 metros cúbicos - 2.431 metros cúbicos

= 159 metros cúbicos

I would say c. Because if you add the 12 to each if the x numbers it adds up to be correct

Answer:

C. y = x + 12

Step-by-step explanation:

As,

y : 14 = 2 (x) + 12

y : 16 = 4 (x) + 12

y : 18 = 6 (x) + 12

y : 20 = 8 (x) + 12

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Answers

Answer:

8 38/45 inches

Step-by-step explanation:

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?

Let us represent:

Length of regular size chocolate bar = x

Length of king size chocolate bar = y

A regular size chocolate bar is 5 and 4/9 inches long.

x = 5 4/9 inches

If the king size bar is 3 and 2/5 inches longer,

Hence:

y = x + 3 2/5 inches

The length of the king size bar is calculated as:

5 4/9 inches + 3 2/5 inches

(5 + 3) + ( 4/9 + 2/5)

Lowest common denominator = 45

8 + (20 + 18/45)

8 38/45 inches
