A map has a scale of 4.5 inches = 36 kilometers. If the distance between two cities is 8.5 inches, what is the actual distance between the cities

68 km

Step-by-step explanation:

A map has a scale of 4.5 inches = 36 km

We need to find the actual distance between the cities if the distance between two cities is 8.5 inches.

We can find 1 inch is equal to what as follows :

1 inch = (36/4.5) km

For 8.5 inches,

Hence, the actual distance between the cities is 68 km.

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^
