Answer:

The correct answer is 13 13/30

Step-by-step explanation:

To find this, start by turning each mixed number into a improper fraction.

4 1/3 = 13/3

9 1/10 = 91/10

Now add these two together by using common denominators.

13/3 + 91/10

130/30 + 273/30

403/30

Now change back to a mixed number

403/30 = 13 13/30

12. Carmen multiplied a non-zero rational number by its additive inverse. Which statement about the product must be true?
nignag [31]

Answer:

<u>Option C. The product was negative.</u>

Step-by-step explanation:

Let the non-zero rational number is = \frac{x}{y}

So, its additive inverse = -\frac{x}{y}

The result of multiplication the non-zero rational number by its additive inverse = \frac{x}{y} *-\frac{x}{y} =-\frac{x^2}{y^2}

We will check the options:

A. The product was the multiplicative inverse of the original number.

<u>Wrong </u>because the product = \frac{x}{y} *-\frac{x}{y} =-\frac{x^2}{y^2}

B. The product was the additive inverse of the original number.

<u>Wrong </u>because the product = \frac{x}{y} *-\frac{x}{y} =-\frac{x^2}{y^2}

C. The product was negative.

<u>True</u>

D. The product was positive.

<u>Wrong </u>because the product was negative.

<u>So, the answer is option C.</u>

Rewrite the expression in the form 5^n<br><br> (5^-8) (5^-10)
oee [108]

Answer:

Step-by-step explanation:

This problem is all about bases and exponents.  Because we have a quotient and the bases are both 5's, that means that we can use the rule of exponents for quotients to rewrite and simplify:

That's the simplification as long as you are "allowed" to leave the exponent as a negative number.
