Hiroshi spends 30 minutes on history homework, 60 minutes on english homework, and x minutes on math homework. one fourth of his total homework time is spent on math. which equation can be used to find the amount of time hiroshi spends on his math homework? a. 1/4(x + 30 + 60) = xb. 1/4(x) = x(30 + 60)c. 1/4x(30 + 60) = xd. 1/4(x) = (30 + 60)

The equation can be used to find the amount of time Hiroshi spends on his math homework is 1/4 (30 + 60 + x) = x ⇒ answer a

Step-by-step explanation:

* Lets read the problem and take the information to solve the problem

- Hiroshi spends 30 minutes on history homework

- Hiroshi spends 60 minutes on English homework

- Hiroshi spends  x minutes on math homework

* From these information

- The total homework time is (30 + 60 + x) minutes

- Hiroshi spends one fourth of his total homework time on math

- The time of math homework is 1/4 the total homework time

∵ The total homework time = (30 + 60 + x)

∵ The time of math homework is 1/4 the total homework time

∴ The time of math homework = 1/4 (30 + 60 + x)

- Then equate the times of math homework

∵ Hiroshi spends  x minutes on math homework

∵ The time of math homework = 1/4 (30 + 60 + x)

∴ 1/4 (30 + 60 + x) = x

* The equation can be used to find the amount of time Hiroshi

  spends on his math homework is 1/4 (30 + 60 + x) = x

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.
