Answer:
14
Step-by-step explanation:
It's a probability, divide favorable outcomes to total outcomes
4/5 of 80 is 64
99-64=35
35/5=7
7x8=56
Answer is 56
Answer: D
Step-by-step explanation:
Answer:
x = -5
y = 6
Step-by-step explanation:
3x + 7y = 27 --------------(I)
-3x + y = 21 -----------(II)
Add equation (I) & (II) and so x will be eliminated and we can find the value of y.
(I) 3x + 7y = 27
(II) <u> -3x + y = 21 </u> {add}
8y = 48
y = 48/8
y = 6
Plugin y = 6 in equation (I)
3x +7*6 = 27
3x + 42 = 27
3x = 27 - 42
3x = -15
x = -15/3
x = -5
Answer:
M=-1/3
Y=-1/3x + 4
