The student who solved the equation made an error(s). Explain the error(s). State the correct solution. (90−x)+2x+x=180
90−4x=180
4x=270
x=67.5

the negative sign before X in the bracket isn't supposed to affect the ones after the bracket

Step-by-step explanation:

(90 - x) + 2x + x = 180

90 - x + 2x + x = 180

90 + 2x = 180

sub. 90 from both sides

2x = 90

x = 45

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
