Answer:
a = $13.5
Step-by-step explanation:
Let a = adult tickets
Let c = children tickets
Translating the word problem into an algebraic equation;
<u>For the Martinez family;</u>
2a + 3c = $60
<u>For the Wright family;</u>
3a + 5c = $95.5
Thus, the simultaneous equations are;
..........equation 1
.........equation 2
We would use substitution method to solve;
From equation 2, we make a the subject of formula;
3a = 95.5 - 5c
a = (95.5 - 5c)/3
<em>Substituting the value of "a" into equation 1, we have;</em>
2[(95.5-5c)/3] + 3c = 60
Multiplying all through by 3;
2(95.5 - 5c) + 9c = 180
191 - 10c + 9c = 180
191 - c = 180
c = 191-180
c = $11
To find the value of a;
2a +3c = 60
<em>Substituting the value of "c" into the equation, we have;</em>
a = $13.5
<em>Therefore, the cost of an adult movie ticket is $13.5. </em>
The answer to this question is:
5/2 or 2.5 or 2 1/2
Up to multiples, if you're given the roots you can write the polynomial by multiplying several parenthesis in the form
where is a root. So, in your case, you have
We can fix the parameter a by imposing f(0)=60:
So, your polynomial is
Answer:
Colt
Step-by-step explanation:
Solve for x in both cases. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and equals:
Parenthesis
Exponents (& roots)
Multiplication
Division
Addition
Subtraction.
Jose:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 3.5 to both sides:
5x - 3.5 = 12.5
5x - 3.5 (+3.5) = 12.5 (+3.5)
5x = 16
Next, divide 5 from both sides:
(5x)/5 = (16)/5
x = 16/5
x = 3.2
Colt:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 3 from both sides:
(x/5) + 3 (-3) = 12 (-3)
x/5 = 12 - 3
x/5 = 9
Next, multiply 5 to both sides:
(x/5)(5) = (9)(5)
x = 9 * 5
x = 45
Colt has the larger solution.
