Mathematics
1 answer:
solmaris [256]3 years ago
5 0

Answer:

x=3

Step-by-step explanation:

<em>3</em><em>x</em><em>-</em><em>4</em><em>=</em><em>8</em><em>-</em><em>x</em><em>(</em><em>Group</em><em> </em><em>like</em><em> </em><em>terms</em><em>)</em>

<em>3</em><em>x</em><em>+</em><em>x</em><em>=</em><em>8</em><em>+</em><em>4</em><em>(</em><em>Add</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>

<em>4</em><em>x</em><em>=</em><em>1</em><em>2</em><em>(</em><em>After</em><em> </em><em>adding</em><em> </em><em>you</em><em> </em><em>will</em><em> </em><em>proceed </em><em>to</em><em> </em><em>divide</em><em> </em><em>both</em><em> </em><em>sides</em><em> </em><em>by</em><em> </em><em>4</em><em>)</em>

<em>x</em><em>=</em><em>3</em><em>(</em><em>x</em><em> </em><em>is</em><em> </em><em>3</em><em> </em><em>because</em><em> </em><em>4</em><em> </em><em>can</em><em> </em><em>divide</em><em> </em><em>1</em><em>2</em><em> </em><em>3</em><em> </em><em>times</em><em> </em><em>that's</em><em> </em><em>why</em><em> </em><em>we</em><em> </em><em>have</em><em> </em><em>x</em><em> </em><em>as</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em><em>3</em><em>)</em>

A collector offers to buy state quarters for $2000\%$ of their face value, which is 25 cents. At that rate how many dollars will
umka21 [38]

Answer:

Bryden will get a total of $20 for this four quarters

Step-by-step explanation:

Here, we have a collector offering to buy state quarters for 2,000% of their face value.

Now, we have 4 state quarters with the value of 1 being 25 cents.

Since 1 has a value of 25 cents, then four will have a face value of 25 cents * 4 = 100 cents or better still $1

Now, the offer is 2000%

So the amount to be paid in dollars will be 2000% of $1.

Mathematically, that would be;

2000/100 * 1 = 2000/100 = $20
