Answer:

x=34

Step-by-step explanation:

If you put Y and X <u>into a ratio</u> then it will be

5:2

because since their GCF is 11, then we will have to <u>divide</u> both of the numbers by <em>11</em>.

If y=85 then that means that it was<u> multiplied by 17</u>. If we want them to <u>stay within the same ratio</u>, then we will have to multiply X (2) by 17.

That will get you 34.

For which value of x must the expression square root of 19x be further simplified? A. 15. B 21. C 28. D 41
algol [13]
<span>The expression of the square root of 19x must be simplified when x is equal to 28. This is because possible factors of 28 can be seen to be 4 and 7, and 4 is a perfect square. This means it can be pulled outside of the square root when evaluated. The other options include only prime factors that could not be pulled out. (3,5), (3,7), (1,41)
   28 simplifies as such:
 Sqrt(19*28) = Sqrt(19*4*7) = 2*Sqrt(19*7) = 2*Sqrt(133).</span>

(1 point) All that is left in a packet of candy are 7 reds, 3 greens, and 3 blues.
Sauron [17]

Answer:

A 21 /169

B independent

Step-by-step explanation:

The total number of candies is 7+3+3 = 13

P( 1st red) = red/total = 7/13

Since the candy is put back there are still 13 candies in the dish

P(2nd green) = green/total = 3/13

P( red, then green) = P( 1st red) * P(2nd green)

                                = 7/13* 3/13 = 21/169

The events are independent since the candies are put back
