Answer:

$\boxed{x = -7~~and~~ y =-7}$

Step-by-step explanation:

y = 3x + 14

y = x

x = 3x + 14

3x - x = -14

2x = -14

$x = \frac{-14}{2}$

x = -7

y = x

y = -7

the pie chart shows the information about the favourite ice cream flavour of each student in a school there are 720 students in

kirill115 [55]

Answer:

chocolate= 180 students

vanilla= 120

strawberry= 210

mango= 210

Step-by-step explanation:

The chocolate section of the pie chart is at a right angle (90 degrees), which means a quarter of the students prefer chocolate

720/4= 180

The vanilla section is 60 degrees which is 2/3 of 90

180/3=60

60x2=120

the mango and strawberry sections represent whats left which is 420 students. The sections are equal to each other so they're each 210 students
