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>
3 nickles plus 8 pennies
(3x5)+(8x1) = 15 + 8 = 23
= 23¢
Answer:
the last choice
Step-by-step explanation:
two functions are said to be inverse when they are symmetric about the line y=x
Answer:
B
Step-by-step explanation:
When you double the dimensions of a triangle, the area is four times as large, so if you quadruple it, it would be 16 times as large
Well I certainly understand why you are having grief. I wonder what we know about this thing? The bottom triangle is easy enough to figure out, but are the lines leading up to it parallel? If they are then 5.2 is not correct, or the right
angle symbol is meant to connect to the vertical line closest to us.
What's all the writing to the left and right. What does it say?
Finally what do you know? Can you find area using Heron's Formula for area. I'm going to hold off saying much. You can put a remark somewhere. The magic editor will pick it up and tell me you've done it.
