Answer:

<em>Total amount of $ at beginning of day ⇒ ( About ) $ 26.1</em>

Step-by-step explanation:

Let us say x represents ⇒ amount of $ at the beginning of the day;

If she spent 1 / 6 of this total money on books, we can say that the amount spent on books is 1/6x. Consecutively if 1/8 of this money was spent on shoes, the amount spent on shoes is 1/8x;

Knowing that $13.50 was remaining, let us set up the following equation;

x - ( 1/6x + 1/8x + 5 ) = 13.50 ⇒ now let us solve for x,

x - ( 1/6x + 1/8x + 5 ) = 13.50 ⇒ add similar elements, expanding,

x - ( 7/24x + 5 ) = 13.50 ⇒ distribute the minus sign

x - 7/24x - 5 = 13.50 ⇒ multiply either side by 24,

17x - 120 = 324 ⇒ add 120 to either side,

17x = 444,

<em>Solution; Total amount of $ at the beginning of day ⇒ ( About ) $ 26.1</em>

Which expression is equivalent to (5.4x10^10) (3.3x10^21)?
natta225 [31]

Although, here are no expressions ! it's an incomplete question. So, showing the answer with general simplification 17.82(10^{31}).

<u>Step-by-step explanation:</u>

We have the expression as (5.4x10^10) (3.3x10^21) which can be further simplified as :

⇒(5.4x10^10) (3.3x10^21)

⇒(5.4(10^{10})(3.3(10^{21})

keep the power terms together and numbers to simply. Hence, we get as below

⇒ (5.4(3.3))(10^{21}.10^{10})

⇒(17.82)(10^{21+10)})

By solving the above, we get final simplified answer as

⇒17.82(10^{31})

Although, here are no expressions ! it's an incomplete question . You may match  17.82(10^{31}) to the listed options wherever!
