Answer: (3/10) in = (7/8) mi
1 in = (7/8) mi ÷ (3/10)
= 7/8 * (10/3) = 70/24
1 in = (70/24) mi
It means every 1 inch on the map drawing represents (70/24) miles ≈ 2.917 miles in reality.
Hope this helps :)

Answer:
(x-2)(x+4)
Step-by-step explanation:
So it would be A.
Explanation: The middle number is 2 and the last number is -8.
Factoring means we want something like
(x+_)(x+_)
Which numbers go in the blanks?
We need two numbers that...
Add together to get 2
Multiply together to get -8
Can you think of the two numbers?
Try -2 and 4:
-2+4 = 2
-2*4 = -8
Fill in the blanks in
(x+_)(x+_)
with -2 and 4 to get...
(x-2)(x+4)
Answer:
(x−2)(x+4)
Answer:
x = 1
Step-by-step explanation:
Solve using inverse operations
5 ( x + 2 ) - 7 = 3x + 5
first distribute the 5
5x + 10 - 7 = 3x + 5
simplify the expression
5x + 3 = 3x + 5
Inverse operations, then simplify
5x + 3 = 3x + 5
-3 -3
5x = 3x + 5 - 3
5x = 3x + 2
-3x -3x
2x = 2
/2 /2
x = 1
