Answer:
x = -2, y = 5/3
Step-by-step explanation:
we have the value of x already (-2).
x=-2
Plug it into the first equation y = 2/3x+3
y = 2/3(-2)+3
y = -4/3+3
y = -4/3+9/3
y = 5/3
x = -2, y = 5/3
Sum of all interior angles of a polygon
180( n - 2) where n = number of sides in the polygon
now, if n = 19, the polygon has 19 sides, then 180( 19 - 2)
Answer:
15 feet per minute.
Step-by-step explanation:
- speed = distance ÷ time
- speed = 450 feet ÷ 30 minutes
- 15 feet per minute = 450 feet ÷ 30 minutes
4/5A=1/2M
4/5Ax2=1/2Mx2
8/5A=1M
1 of M = 8/5 of A
Answer:
3.75 minutes
Step-by-step explanation:
Set up an equation where x is the number of minutes:
0.25x + 35 = 0.5x + 20
Solve for x:
0.25x + 35 = 0.5x + 20
35 = 0.25x + 20
15 = 0.25x
3.75 = x
So, both plans will cost the same with 3.75 minutes
