Answer:

Step-by-step explanation:

$12(4x - 5) + \frac{5}{2}=10$

Multiply the whole equation by 2

$2*12(4x -5) + \frac{5}{2}*2=10*2\\\\24(4x-5) + 2 = 20\\$

24*4x - 5*24 + 2 = 20

96x - 120 + 2 = 20

96x - 118 = 20

Add 118 to both sides

96x = 20 +118

96x = 138

Divide both sides by 96

x = 138/96 = 23/16

$x = 1 \frac{7}{16}$

John leaves his home. He travels 5 blocks south and three blocks west. As the crow flies, how far is John from his home?

riadik2000 [5.3K]

Answer:

5.83 blocks away from his home

Step-by-step explanation:

If he travels 5 blocks south and 3 blocks west, the distance from his house considered along with the distances travelled gives a right angled triangle whose opposite side and adjacent sides are the distances travelled north and west.

The distance from his house after moving 3 blocks west is the hypotenuse side. As such, the distance may be computed using Pythagoras' theorem. Let the distance from his house be G

G^2 = 5^2 + 3^2

G^2 = 25 + 9

= 34

G = √34

=5.83

John is 5.83 blocks away from his home
