Answer:
The 3 statements that are correct are:
<em><u>1. "Plan A offers fewer movies than Plan B for monthly costs greater than 20$"</u></em>
<em><u>2. "The two plans cost the same for 10 movies per month"</u></em>
<em><u>3. "The two plans offer the same number of movies for 20$ a month."</u></em>
Answer:
a. True
b. False
c. True (I'm not 100% certain but I believe that it is true)
d. True
Step-by-step explanation:
It represents a proportional and linear relationship.
It costs $9.75 for each ticket.
No because 3 x 4 = 12 and 8 x 4 ≠ 24
Answer:
4
Step-by-step explanation:
If x is the third number, then x−1 and x−2 are the second and first numbers.
10(x−2) + 10(x−1) = 10 + 10x
x − 2 + x − 1 = 1 + x
2x − 3 = 1 + x
x = 4
Answer:
x=2√5
Step-by-step explanation:
<u>1st method:</u>
sin(30)=opposite/hypotenuse=√5/x
sin(30)x=√5
x=√5/sin(30)
x=2√5
<u>2nd method:</u>
cos(60)=adjacent/hypotenuse=√5/x
cos(60)x=√5
x=√5/cos(60)
x=2√5
<u>3rd method:</u>
This is a 30-60-90 triangle, so we can multiply the short side, √5, by 2, to get x=2√5
