The table shows the amount of lemon juice needed to make lemonade. (Unit 9 Lesson 3) Lemon juice (cups) 5 10 20 Servings 35 70 1
40 Are the two quantities proportional? If so, what is the constant of proportionality?
1 answer:
Lemon Juice (cups) 5 10 20
Servings 35 70 140
The two quantities are proportional. Lemon Juice (cups) is the x-value ; while servings is the y-value.
35 ÷ 5 = 7
70 ÷ 10 = 7
140 ÷ 20 = 7
The constant of proportionality is 7.
The equation would be: y = 7x

Answer:
x>15
Step-by-step explanation:
Given the inequality: 2x + 10 < 4x - 20
Collect like terms
2x-4x<-20-10
-2x<-30
x > -30/-2
x>15
Hence the solution is x>15
