The pattern of the signs follows the acronym SOAP
S = same sign as the cubes
O = opposite sins of the cubes
AP = always positive

Step-by-step explanation:
2. The scale is 3 inches = 2 feet.
Divide total inches by 3, then multiply by 2:
30 / 3 = 10
10*2 = 20 feet.
3. Divide the 9cm by 3cm, then multiply by 8 km
9/3 = 3
3*8 = 24 kilometers.
4. Divide real distance by distance on map:
36 / 4 = 9
1 inch = 9 miles
5. Divide real dimension by the drawing dimension:
21 meters / 3 centimeters = 7
1 cm = 7 meters
Yes, because I think two could work
Answer:
x=-11/8
Step-by-step explanation:
x-(5/8)=-2
Give the -2 a common denominator to make it easy
x-(5/8)= -16/8
Add the 5/8 to the -16/8
x= -11/8
It is .6 because 6 doesn't repeat and by the 10 you go left one
