Ascale on a hiking map shows that 3 inches represents 1.2 miles. what number of inches on the map represent 10 actual miles?

Divide 10 actual miles by 1.2 miles:

10 / 1.2 = 8.333

multiply that by 3 inches:

8.333 x 3 = 25

10 miles would be 25 inches on the map.

25 inches on the map represent 10 actual miles.

Step-by-step explanation:

Hi, to answer this question we have to express the information given in ratios:

3 inches represent 1.2 miles = 3/12

x inches represent 10 miles= x/10

Since the ratios are the same

3/1.2 = x/10

Solving for x

(3/1.2) 10 = x

25 inches =x

25 inches on the map represent 10 actual miles.

Feel free to ask for more if needed or if you did not understand something.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
