Solve the system by substitution.<br> - 2 + 3y = 20<br> 7y = x

Savatey [412]

Answer:

x = 22, y = 22/7

Step-by-step explanation:

solve for y using first equation:

-2 + 3y = 20

3y = 22

y = 22/7

substitute 22/7 into second equation:

7y = x

7(22/7) = x

x = 22

You ask 125 randomly chosen students to name their favorite food. There are 1500 students in the school. Predict the number of s

alekssr [168]

You need to find the percent of the 125 surveyed students to find the number of estimated students that like pizza.

58/125 = .464 or 46.4%

1500*.464 = 696 students like pizza.

Hope this helps!
