Answer:

17 7/8

Step-by-step explanation:

8 1/8 = 65/8

9 3/4 = 39/4 = 78/8

8 1/8 + 9 3/4

= 65/8 + 78/8

= (65 + 78) / 8

= 143/8

= (17*8 + 7) / 8

= (17*8)/8 + 7/8

= 17 7/8

Answer:

17 7/8

Step-by-step explanation:

First, we need to find the Least Common Denominator.

We know that 8 is evenly divisible by 4, so lets make the problem 8 1/8 + 9 6/8

We can add 6 to 1, which gets 7, or 7/8

We can add 8 to 9, which gets 17

So out final answer is 17 7/8

Step-by-step explanation:

The ratio of acid to mixture volume is ...

(0.62·175 +1.00·75)/(175 +75) = 183.5/250 = 0.734 = 73.4%

Which expression is equivalent to -18a^-2b^5/-12a^-4b^-6

crimeas [40]

Answer:

c. 3a^2b^11/2

Step-by-step explanation:

The applicable rule of exponents is ...

(a^b)/(a^c) = a^(b-c)

$\dfrac{-18a^{-2}b^5}{-12a^{-4}b^{-6}}=\dfrac{-18}{-12}a^{-2-(-4)}b^{5-(-6)}=\boxed{\dfrac{3a^2b^{11}}{2}}$
