Answer:
33/4 or 8 1/4
Step-by-step explanation:
-1/2=-2/3x + 5
-5 -5
---------------------
-11/2= -2/3x
____ _____
-2/3 -2/3
---------------------
33/4 = x
Check:
-1/2 = -2/3(33/4) + 5
-1/2 = -11/2 + 5
-1/2 = -1/2
Okay so question is
x^2-10x + 26 = 8
Lets simplify it
x^2-10x+18=0
Let's solve your equation step-by-step.<span><span><span><span>x2</span>−<span>10x</span></span>+18</span>=0

Answer:
Check the explanation
Step-by-step explanation:
(a) Best decision based on maximax criterion= large facility
maximum in the two facilities is $300 and $800 of which $800 is the maximum, So larger facility satisfies maximax.
(b) Best decision based on maximin criterion= small facility
minimum in the two facilities is $100 and -$200 of which $100 is the maximum, So smaller facility satisfies maximin.
(c) Best decision based on minimax regret= large facility
maximum in the two facilities is $300 and $800 of which $300 is the minimum, So larger facility satisfies minimax regret.
Answer:
171
Step-by-step explanation:
Step 1: Let "x" and "y" be the variables
Let x = the number of adult tickets sold
Let y = the number of child tickets sold
Step 2: Add the variables and subtract the "x" variable
x + y = 486 y = 486 - x
Step 3: Add the given amounts by the variables next to it to equal the total
5.50x + 4y = 2416.50
5.50x + 4(486 - x) = 2416.50
5.50x + 1944 - 4x = 2416.50
Step 4: Subtracting the result from the number of tickets the booth sold
1.5x = 472.5
x = 315
y = 486 - 315 = 171
Therefore, there are 171 tickets of each type sold.
