Answer:

x = -5

Step-by-step explanation:

-7x + 5(2x - 1) = -20 (Given)

-7x + 10x - 5 = -20 (Simplify)

3x - 5 = -20 (Simplify)

3x - 5 + 5 = -20 + 5 (Addition Property of Equality)

3x = -15 (Simplify)

$\frac{3x}{3} = \frac{-15}{3}$ (Division Property of Equality)

x = -5 (Simplify)

The difference from home to

Amanda [17]

Answer:

$\frac{3}{8}\ mile$

Step-by-step explanation:

-Amy walks a distance of 7/8 mile

-Tom walks a distance of 4/8 mile.

#We immediately notice that Amy has walked a longer distance than Tom.

We subtract Tom's distance from Amy's to find how much further Amy walked;

$\bigtriangleup d=d_A-d_T\\\\=\frac{7}{8}-\frac{4}{8}\\\\=\frac{3}{8} mile$

Hence, Amy has walked 3/8 miles further than Tom has.
