Answer:
a. 95
b. 86
Step-by-step explanation:
Since you need it quick, no explanation for now.
If you are solving for the question in the picture your answer would be 18. Whiich is letter A.
12x+15y=390 Original Equation
12(10)+15y=390 Replace x with 10
120 + 15y= 390 Mutiply 12 by 10
-120 = -120 subtract 120 on both sides to simplfy the equation
15y= 270 New equation
÷15 = ÷15 To get the variable alone divide 15 on both sides
y=18 Your value for y.
Answer: infinitely many solutions.
Step-by-step explanation:
Ok, our equation is:
-2.1*b + 5.3 = b - 3.1*b + 5.3
now, simplifyng the right side, we have:
b - 3.1*b + 5.3 = (1 - 3.1)*b + 5.3 = -2.1*b + 5.3
Then our initial expression is:
-2.1*b + 5.3 = -2.1*b + 5.3
So in both sides of the equality we have the exact same thing, so this is a trivial equality.
This means that the equality will remain true for any value of b, which means that we have infinitely many solutions.
Answer:
Step-by-step explanation:
The sample space in a 3 times die roll =63=216.
Now, P(getting at least one 6)=1−P(getting NO 6).
Probability of getting no 6 in a single die roll
=56.
Thus probability of getting NO 6 in three die rolls
=56×56×56=125216.
Therefore, the probability of getting at least one 6
P=1−125216=91216.
