Rewrite ×3×3×33 using an exponent
Anna11 [10]
the exponent tells you how many times to multiply the base number by itself.   for 35 the base number or base is 3 and the exponent is 5   the value is 3 x 3 x 3 x 3 x 3 which has 3 multiplied by itself five times   So your question is going in the opposite direction.   Rather than going from a power and expanding it, we have the expanded form and we are asked to write the power   3 x 3 x 3 is written  33

3) David goes into a candy store with $5.00. He buys 9 peppermints for $0.15
yuradex [85]
<h3>Write an equation that will match the story problem​</h3>

x=(5 - (9 \times 0.15) ) \div 0.25

<em><u>Solution:</u></em>

Given that,

David goes into a candy store with $5.00

Total amount with David = $ 5

He buys 9 peppermints for $0.15 each

And some sour candies. each sour candy costs $0.25

The equation is:

Let the number of sour candies bought be "x"

Then,

Remaining amount after buying pepper mint = 5 - 9 \times 0.15  = 3.65

Each sour candy cost $0.25

<em><u>Now the number of sour candies bought is:</u></em>

3.65 = 0.25 \times x

x = 14.6

Thus david can buy 14 sour candies

<em><u>Thus the equation that will match the story problem​ is:</u></em>

x=(5 - (9 \times 0.15) ) \div 0.25

Where, "x" means number of sour candies bought
