R - 5 1/6 = 10
r - 31/6 = 10
+ 31/6 +31/6
r = 91/6
So, r = 91/6.
And, I am not sure if the second one I am doing in right or wrong, but I am just guessing.
I think you use substitution method here.
8(x-2)+9 = 14
8x-16+9 = 14
8x-7 = 14
+7 +7
8x = 21
x = 21/8
So, the answer is 21/8
HOPE THID HELPS AND I REALLY HOPE THAT THE SECOND ANSWER IS RIGHT!!!!!!
Answer:
Hi There the correct answer is {x,y} = {-1,-10}
System of Linear Equations entered :
[1] 3x - y = 7
[2] 4x - 2y = 16
Graphic Representation of the Equations :
y + 3x = 7 -2y + 4x = 16
Solve by Substitution :
// Solve equation [1] for the variable y
[1] y = 3x - 7
// Plug this in for variable y in equation [2]
[2] 4x - 2•(3x-7) = 16
[2] -2x = 2
// Solve equation [2] for the variable x
[2] 2x = - 2
[2] x = - 1
// By now we know this much :
x = -1
y = 3x-7
// Use the x value to solve for y
y = 3(-1)-7 = -10
Solution :
{x,y} = {-1,-10}
Hope it helps!
<h3>The exact probability that the blue ball is drawn first and the red ball is drawn second is
</h3>
<em><u>Solution:</u></em>
<em><u>The probability of an event is given as:</u></em>
Given that,
There are 12 balls in a bag
One is blue and one is red
Favorable outcome = blue ball is drawn first
Favorable outcome = 1
Therefore,
Now, without replacement, red ball is drawn second
Therefore,
Total possible outcomes = 12 - 1 = 11
<em><u>What is the exact probability that the blue ball is drawn first and the red ball is drawn second?</u></em>
Thus the exact probability that the blue ball is drawn first and the red ball is drawn second is
Simple...there'a a LOT of combinations...
so to simply solve this;there is 5 appetizers, 7 entrees and 3 desserts....
Just take 5*7=35
and
35*3=105
Thu,s there is 105 combinations possible to make.
Thus, your answer, D.
