The first answer is B: 2 1/2

4 5/6 is put there twice except the last one is subtracting so you can put, 4 5/6 - 4 5/6 = 0 therefore the only number left is 2 1/2

the second one I really don't know sorry:(

The third answer is C because the cases come in 24. But they didn't tell you how many case she brought so the variable has to be by 24 and they took 43 which is the subtracting factor. So the answer is C.

And I also don't know the last one again sorry:(

The mean of 4 8 9 x and 2x is 6 calculate the value of x

Paul [167]

Answer:

x = 3

Step-by-step explanation:

Mathematically, the mean is the sum of the numbers divided by the count of the numbers

The count of the numbers is 5

Thus;

( 4 + 8 + 9 + x + 2x)/5 = 6

(21 + 3x)/5 = 6

21 + 3x = 6(5)

21 + 3x = 30

3x = 30-21

3x = 9

x = 9/3

x = 3

Angle RZT=110<br> Angle RZS=3s<br> Angle TZS=8s<br> What are angles RZS and TZS?

nekit [7.7K]

Angles RZT, RZS, and TZS form triangle RZT, so they sum to 180. Thus, we have:

110+3s+8s=180

Simplifying, we have:

11s=70

Dividing by 11, we see that:

s=70/11

Therefore, RZS=3s=210/11, and TZS=8s=560/11.

How many times bigger is 1.8x10^27 than 1x10^25

victus00 [196]

To find the number of times it is bigger

$= \dfrac{1.8 \times 10^{27} }{1 \times 10^{25}}$

$= 1.8 \times 10^{27-25}$

$= 1.8 \times 10^{2}$

$= 180 \text { times}$
