You are walking down the street one day minding your own business when you spot a small but heavy leather bag lying on the sidewalk. It turns out to contain U. S. Mint American Eagle gold coins of the following types: - 1/4 oz gold coins that sell for $150 each, and
- 1/10 oz gold coins that sell for $70 each
A bank reciept in the bag certifies that it contains 68 such coins with a total value of exactly $8120. Immediately you wonder how much all of those coins must weigh! Set up a system of equations related to this scenario, and solve it. Then deduce the total weight of the coins in the bag.

answer: the answer is 30 miles per hour.

ft/s -> mphmph = ft/s 1.466667mph = 44 divided by 1.466667mph = 30.00000

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
