Treat this as an ordinary linear equation. Try to isolate x, as some value. Also remember the basic rules of inequalities: If you're dividing, or multiplying, by a negative, you flip the inequality.
Answer:
A) 2.50
Step-by-step explanation:
subtract 8.75 and 6.25 to get the cost of 1 pizza slice since Alfredo bought 1 more pizza than Jessica.
Supplementary means they add up to 180
X + 54 = 180
180-54= x
X = 126
126+54=180?
Yep
So your answer is
126
Solve for K by simplifying both sides of the equation, then isolate the variable.
K = 193
