Answer:
187
Step-by-step explanation:
We make an equation to find the average of all three games: (139+184+x)/3=170 . x is the value of the third game to get an outcome of at least 170, and when you solve the equation you get 187.
Answer:
Step-by-step explanation:
The area of the equilateral triangle is 
Pythagorean Theorem is for right triangles
right triangles have a 90 degree angle in them
D is a right triangle
40/8=5
$5= 1gal.
5x10=50
So 10 gallons of gas costs $50
Answer:
y = -2x - 2
Step-by-step explanation:
Given:
m = -2
Slope-intercept:
y - y1 = m(x - x1)
y + 8 = -2(x - 3)
y + 8 = -2x + 6
y = -2x - 2
