I think that it would be D
Answer:
x = -8
Step-by-step explanation:
16+6-6x-4=-7x+3+7
Combine like terms
18 -6x = -7x+10
Add 7x to each side
18-6x+7x = -7x+7x+10
18+x = 10
Subtract 18 from each side
18+x-18 = 10-18
x = -8
Answer: Option A: 5
Step-by-step explanation:
If yo have the pairs (a, b) and (c, d)
The distance between these two points is:
distance = √( (a - c)^2 + (b - d)^2)
Here we want to find the distance between points B and C.
We can see that the coordinates of each one are:
point B: (-5, 5)
Point C: (-1, 2)
Then the distance between these points is:
AB = √( (-5 -(-1))^2 + (5 -2)^2) = 5
AB = √( 4^2 + 3^2)
Then the correct option is A
Answer:
144 miles
Step-by-step explanation:
The scale of map B is (3.4 cm)/(6.8 cm) = 1/2 that of map A. Then the distance (d) between the cities is ...
(1.8 cm)/d = (1/2)·(1 cm)/(40 mi)
Multiplying by d·80 mi, we get ...
144 mi·cm = d cm
Dividing by cm, we have ...
144 mi = d
The distance from Gladville to Columbus is 144 miles.
