A scale drawing is an enlarged or reduced drawing of an object that is similar to an actual object. Maps and floor plans are smaller than the actual size. A scale drawing of a human cell is larger than the actual size.
On a map, the equal sign in 1 in. = 30 mi does not mean that the two quantities are equal, as it would in an equation.
A scale is the ratio that compares a length in a drawing to the corresponding length in the actual object. If a 30-mile road is 1 in. long on a map, you can write the scale of the map in these three ways:

Step-by-step explanation:
i think it was ASA
Multiply 8 by x and 8 times 2 you should get 8x+16. Divide 8x by 8 and divide 16 by 8. Leaving x=2
Skateboard: $60.00
Equipment only: $1.50
Skateboard + Equipment: $5.50
In this case, you would take the cost of the skateboard: $60 and divide $5.50 (all items) to get the number of hours.
Which would be "10.9090"... If we round it we get 11 hours...
This should be correct. <3
This is the concept of algebra,
The fraction of children was: 3/8
fraction of adults was 1-3/8=5/8
fraction of men 3/4*5/8=15/32
fraction of women=5/8-15/32=5/32
Given that there was 140 more children than men, the fraction representing this will be:
(3/8-5/32)
=7/32
thus the total number of people will be:
1/(7/32)*140
=32/7*140
=640
the total number of people was 640
