Answer:
a & d
Step-by-step explanation:
got them right om edge
So this translates to:
5e + 5n = 25.95
2e + 6n = 22.38
One way to solve that is to multiply the top equation by 2, and the bottom equation by 5:
10e + 10n = 51.90
10e + 30n = 111.90
Then subtract the top from the bottom to get:
20n = 60
and divide by 20 to get
n = 3
So you know that note paper costs $3. Substituting that into the top equation you get:
5e + 5*3 = 25.95 or
5e + 15 = 25.95
Subtracting 15 from both sides you get:
5e = 10.95
Dividing by 5 you get:
e = $2.19
28.5 is the Answer i thinck i do not now i forgot how to do it in college we do not do that any more
Answer:
Length AB = 1
Length CD = 3
Length EF = 2
Step-by-step explanation:
To get the length of each line segments we will use the formula for finding the distance between two points as shown:
D = √(x2-x1)²+(y2-y1)²
For line segment A = (3,5) and B = (3,6)
x1 = 3, y1 = 5, x2 = 3, y2 = 6
AB = √(3-3)²+(6-5)²
AB = √0+1²
AB = √1
AB = 1
For line segment C = (-2,-3) and D = (-2,-6)
CD =√(-2-(-2))²+(-6-(-3))²
CD = √0²+(-3)²
CD = √9
CD = 3
For line segment E = (-3,1) and F = (-3,-1)
EF = √(-3-(-3))²+(-1-1)²
EF = √0²+(-2)²
EF = √4
EF = 2
