Since the area of the rectangle is 30, we know the following:
(5)(x-2) = 30
Divide both sides by 5
x-2 = 6
Add both sides by 2
x = 8
That's your answer.
Have an awesome day! :)
Probability is favorable outcome to total possibilities.
So, any probability will be x/80
There are 36 seventh graders, and 22 girls in eighth grade (40-18=22). 36+22=58
The probability of drawing either a seventh grader or a girl is 58/80, or 72.5%
It would be 64 because 12 times 2 is 24 and 32 time 2 is 64
Answer:
B) Y=-2x+1
Step-by-step explanation:
(-2,5)(2,-3)
M= -8/4 = -2
y = -2x + b
5 = -2(-2)+ b
B= 1
Y=-2x+1
Step-by-step explanation:
elimination of x:
-6x +5y = 1
6x + 4y = -10
___________+
9y = -9
y = -9/9 = -1
elimination of y:
-24x +20y = 4
30x + 20y = -50
_____________-
-54x = 54
x = 54/-54 = -1
{ -1, -1}
