It should be 7.5

If i’m doing the math correctly it should work like PEMDAS. i did the (2.4+5.1) and got 7.5

If you have to completely answer the problem you will do the 6 squared which would equal 36. 36+7.5+3.5=47.

kakasveta [241]

Answer:

x =  -12

y = 3

Step-by-step explanation:

1/2x + 6(x+15) = 12\\1/2x + 6x + 90 = 12\\6\frac{1}{2} x + 90 = 12\\6\frac{1}{2} x= -78\\x = -12

y = x + 15\\y = -12 + 15\\y = 3

Step-by-step explanation:

slope is the average rate of change in a specific interval

we can calculate slope in this case with Δy/Δx or (y2-y1)/(x2-x1)

m=(y2-y1)/(x2-x1)

=(-1-7)/(-3-1)

=-8/-4

Since there are 22 participants all in all. The possible combinations of the two picked for practice first is, 
                               22C2 = 231
The probability of picking one from each gender will be solved through the calculation below.
                              (10C1)x(12C1) / 231 = 40/77
In percentage, the answer would be approximately 52%. Thus, the answer is the first choice.
