Answer:
if 3 inches on a map = 42miles
then x = 322miles
cross multiply
3inches by 322 = xby42miles
966inchesmiles = 42xinchesmiles
divide both sides by 42miles
xinchees = 23
therefore 322miles distance will take 23inches on a map
Answer:
x = 7 m and x = −7 m
Step-by-step explanation:
Its a modulus problem
concept
|x| = x when x>=0
|x| = -x when x < 0
____________________________________
Now given
|x| − 2 = 5
adding 2 both sides
|x| − 2 + 2 = 5 + 2
|x| = 7
now
x = 7 when x >= 0
x = -7 when x<0
Thus, correct answer is x = 7 m and x = −7 m
