Answer:
-14
Step-by-step explanation:
Substitute the values for the variables.

60 plain pizzas last week
42 fewer pizzas this week
Number of pizzas sold this week = 60 - 42 = 18
60 ------------------------- 100
18 ------------------------ x
x = (18 x 100)/60
x = 1800/60
x = 30%
The percent change will be 100 - 30 = 70%
Answer:
800
Step-by-step explanation:
100x216=27
21600 divided by 27=800
Answer:
2x+3y+5=0
a = 2 b = 3 c=5
Step-by-step explanation:
We are asked to express 2x+3y=-5 in the form ax+by+c=0
Add 5 to both sides
2x+3y+5=0
We can now find the values of a, b and c now that the equation is in standard form.
