The answer is 9.75 the steps are....
first simplify both sides so...
<span><span>−<span>1.6<span>(<span><span>2c</span>+12</span>)</span></span></span>=12</span><span><span><span><span>(<span>−1.6</span>)</span><span>(<span>2c</span>)</span></span>+<span><span>(<span>−1.6</span>)</span><span>(12)</span></span></span>=12</span>(Distribute)<span><span><span><span>−<span>3.2c</span></span>+</span>−19.2</span>=12</span><span><span><span>−<span>3.2c</span></span>−19.2</span>=<span>12
then add 19.2 to both sides because your trying to get the c by itself..
</span></span><span><span><span><span>−<span>3.2c</span></span>−19.2</span>+19.2</span>=<span>12+19.2</span></span><span><span>−<span>3.2c</span></span>=<span>31.2
and then finally divides both sides by -3.2 so that c will be by itself
AND THEN..you get 9.75</span></span>

Choose yes or no to tell whether the expression represents a 20% discount off the price of an item that originally costs d dolla

tester [92]

Answer:

Option A and C is correct.

Step-by-step explanation:

Discount is defined as a reduced price on something being sold or at a price lower than that item is normally sold for.

For a 20% discount,

Given:

Initial prices = $ d

Discounted price = % discount × original/initial cost

= 20/100 × d

= 0.2 × d

Selling price = original cost - discounted price

= d - 0.2d

= 0.8 × d

= 0.8d

A culture started with 3000 bacteria. After 2 hours it grew to 3300 bacteria. Predict how many bacteria will be present after 16

bixtya [17]

Answer:

$6,430\ bacteria$

Step-by-step explanation:

we have a exponential function of the form

$y=a(1+r)^{x}$

where

y is the population of bacteria

a is the initial value

r is the rate of growth

x is the number of hours

we have

a=3,000 bacteria

$y=3,000(1+r)^{x}$

For x=2, y=3,300

substitute

$3,300=3,000(1+r)^{2}$

$(3,300/3,000)=(1+r)^{2}$

Apply square root both sides

$1+r=\sqrt{3.3/3}$

$r=\sqrt{3.3/3}-1$

$r=0.0488$

$r=4.88\%$

substitute in the equation

$y=3,000(1+0.0488)^{x}$

$y=3,000(1.0488)^{x}$

<u><em>Predict how many bacteria will be present after 16 hours</em></u>

For x=16 hours

substitute

$y=3,000(1.0488)^{16}$

$y=6,430\ bacteria$
