8 1/4 divied by d = 2/11 what is d

Luda [366]

Answer:

d = 363/8

Step-by-step explanation:

Let's write this as a fraction:

8 1/4 2

------------- = -------

d 11

One way in which this could be approached would be to interchange 'd' and '2:'

8 1/4 d 33 d

------------- = ------- or -------- = ---------

2 11 4(2) 11

Multiplying both sides by 11 isolates d:

33(11) 363

-------- = d, or d = ----------

What is the answer for this problem in the picture

DENIUS [597]

Answer:

The correct answer option is $= 8 x ^ 4 y z ^ 4 \sqrt{2yz}$ .

Step-by-step explanation:

We are given the following expression and we are to simplify it and determine whether which of the given expressions is equivalent to it, assuming $y\geq 0$ and $z\geq 0$ :

$\sqrt { 128 x ^ 8 y ^ 3 z ^ 9 }$

Breaking the terms to get:

$\sqrt { 128 x ^ 8 y ^ 3 z ^ 9 }$ $=8\sqrt{2yz} \times x^{8\times\frac{1}{2} } \times y^{2\times \frac{1}{2} } \times z^{8\times \frac{1}{2} }$

$= 8 x ^ 4 y z ^ 4 \sqrt{2yz}$

Solve the system -0.18x + y = -6.54 -2.8x - y = -2.4

bogdanovich [222]

ADDING THE 2 EQUATIONS TO ELIMINATE Y WE HAVE

-2.98x = -8.94
x = 3

Plug x=3 into first equation:-
-0.18(3) + y = -6.54
y = -6.54 +0.54 = -6

answer x= 3 and y= -6.
