Hi there, 3+-10=-7 so, -7+5x=13. First, we add -7 to both sides, which gives us 5x=13+7, 13+7=20, so 5x=20. Now, we divide both sides by 5, Therefore, x=4

3+5x-10=13
Put all like terms together.
5x+3-10=13
5x-7=13
Subtract.
5x=20
Divide.
x=4

Hope this helps :)

These two maps show the same area at two different scales. Colombus is not on Map A. Scale on Map A, 1 cm = 40 mi. Map B does no

dimaraw [331]

Answer:

144 miles

Step-by-step explanation:

The scale of map B is (3.4 cm)/(6.8 cm) = 1/2 that of map A. Then the distance (d) between the cities is ...

(1.8 cm)/d = (1/2)·(1 cm)/(40 mi)

Multiplying by d·80 mi, we get ...

144 mi·cm = d cm

Dividing by cm, we have ...

144 mi = d

The distance from Gladville to Columbus is 144 miles.
