Answer:

-7

Step-by-step explanation:

We can follow PEMDAS and see that first we do 4+2 which is 6.  Our equation looks like 5 - (6)2.  Since multiplication comes before subtraction we multiply 6 * 2 which is 12. Now we can fit that in 5 - 12 = -7

The answer

What is the value of y?

According to the image, HKJ and FGH are similar, we can apply the theorem of thales
since GK and GF are parallels, so 

HK / HF = HJ / HG = KJ / GF and as we see on the figure, HK = HF /2, this implies  2HK =HF

HK / 2HK =  KJ / GF  it is equivalent to   1/2 = 2y+5 / 5y +3 

likewise, equivalent to  5y +3  = 4y +10, 5y-4y = 10-3, and y = 7


so the answer is 7

the probability of picking both would be 1/10 * 1/9 = 1/90
