Answer:

Solve for x.

Step 1: Add y to both sides.

2x−y+y=120+y

2x=y+120

Step 2: Divide both sides by 2.

\frac{2x}{2} = \frac{y+120}{2}

x = \frac{1}{2}y + 60

solve for y.

Step 1: Add -2x to both sides.

2x−y+−2x=120+−2x

−y=−2x+120

Step 2: Divide both sides by -1

\frac{-y}{-1} = \frac{-2x + 120}{-1}

y=2x−120

I NEED HELP CROWN FOR RIGHT ANSWER
natta225 [31]

Answer:

D. $81,728

Step-by-step explanation:

Let's first convert pounds to ounces.

4 pounds x (16 ounces / pound) = <u>64 ounces.</u> (Remember that when we're converting from a larger unit, pounds, to a smaller one, ounces, we'll have more ounces than pounds, so this answer makes sense!)

Let's now get the cost of the gold.

64 oz x ($1277 / oz) = <u>$81,728.</u> (Wow, that's a lot of gold!)
