Since each table had 7 women and 3 men at each table, that would mean each table has 10 people. Since there are 9 tables he was waiting on, and 10 people at each table, multiply 9 x 10, and you will find that he served 90 people in total.
Answer:
Step-by-step explanation:
The given system of equations is 4x - 9y = 7 and -2x + 3y = 4
In this system of equations in order to eliminate the x- terms we will multiply by a number so that coefficients of x may become same.
Therefore, to eliminate the x - terms we multiply second equation by 2.
Similarly to eliminate the y-terms we will multiply the equation by a number so that coefficient of y in both the equations become same.
Therefore, we will multiply second equation by 3.
The relationship iof the ostrich running at 43 miles per hour is proportional.
<h3>Speed of the ostrich</h3>
Since speed = distance per unit time
The speed of the ostrich is 43 miles per hour. This means that the ostrich covers a distance of 43 miles every hour.
Since the ostrich always covers a distance of 43 miles every hour, we see that distance is proportional to time.
So, the relationship iof the ostrich running at 43 miles per hour is proportional.
