A map with a scale of 1 inch : 10 miles is used to make a map with a scale of 1 inch : 20 miles. The distance from one city to another on the map with scale 1 inch : 10 miles is 5 inches. How can you find the corresponding distance on the map with scale 1 inch : 20 miles? Multiply 5 by 1/20.
Multiply 5 by 1/2.
Multiply 5 by 20.
Multiply 5 by 2.

if x = 1, then the answer is 3.5

6(h+1)/2=a

a=area

step-by-step explanation:

its the same thing as a square or rectangle but after multiplying two sides you need to divide it by two.

delaney would like to make a 5lb nut mixture that is 60% peanuts and 40% almonds.

she has several pounds of peanuts and several pounds of a mixture that is 20% peanuts and 80% almonds.

let 'p' represent the number of pounds of peanuts needed to make the new mixture, and  

let 'm' represent the number of pounds of the 80% almond-20% peanut mixture.

:

p + m = 5

therefore

m = (5-p)

write an equation based on the percent of peanuts

1p + .2m = .6(5)

replace m with (5-p)

p + .2(5-p) = .6(5)

p + 1 - .2p = 3

p - .2p = 3 - 1

.8p = 2

p = 2/.8

p = 2.5 lbs of peanuts required

then

5 - 2.5 = 2.5 lbs of the peanut/almond mixture required

:

a) what is the system that models this situation?

p + m = 5

1p + .2m = .6(5)
