Answer:

One family made $1,154 and the other family made $486.

Step-by-step explanation:

Let be "f" the amount of money (in dollars) one of the families made at the garage sale and "s" the amount of money (in dollars) the second family made at the garage sale.

Set up a system of equations:

\left \{ {{f+s=1,640} \atop {f=2s+182}} \right.

You need to use the Substitution Method to solve this system of equations:

1. Substitute the second equation into the first equation.

2. Solve for "s".

Then:

2s+182+s=1,640\\\\3s=1,458\\\\s=\frac{1,458}{3}\\\\s=486

3. Substitute the value of "s" into the second equation and then evaluate in order to find the value of "f". This is:

f=2(486)+182\\\\f=1,154

Destin walked 2km and Jane walked 4,000 ft. What is the approximate combined distance they walked? Note: 1 Foot (ft) is equal to
Anna11 [10]

Answer: Option C.

Step-by-step explanation:

The data is:

Destin walked 2km

Jane walked 4000ft.

Let's write both of those in the same units.

The data given is:

1ft = 0.0003048km.

and 4000ft is 4000 times that:

4000ft = 4000*1ft = 4000*0.0003048km = 1.22km

Then if we add those, we get:

Total distance = 2km + 1.22km = 3.22km

So we can already discard option D.

Now, we know that:

1km = 0.6214 miles.

then 3.22 km is 3.22 times that amount:

3.22km = 3.22*1km = 3.22*(0.6214 mi) = 2 miles

The correct option is C.
