A graph of this inequality would be a number line, with the number -2 circled (not filled in), and the number line to the right of -2 shaded.
To solve this, you will combine like terms first:
-3x-7x < 20
-10x < 20
Divide both sides by -10:
-10x/-10 < 20/-10
When you divide an inequality by a negative number, you flip the inequality symbol:
x > -2
Answer:
x ≈ 8.66
Step-by-step explanation:
Using the sine ratio in the right triangle
sin60° = 
= 
Multiply both sides by 10
10 × sin60° = x, thus
x ≈ 8.66 ( to 2 dec. places )
Use distributive property to solve.
2x(5x+3) + 7(5x+3)
1. distribute
2x•5x = 10x^2
2x•3= 6x
10x^2+6x
7•5x = 35x
7•3= 21
35x+21
2. combine like terms
10x^2+6x+35x+21
10x^+ 41x +21 [final answer]
20L = 20,000mL. 20,000 / (22+3) people = 800mL/person
