Answer:
See the figure attached
Step-by-step explanation:
Let's call :
x: positive response
y: negative response
then the score is:
2x - 3y
A career placement test eliminates a profession when a person receives a score of 18 or less, that's represented by the following inequality:
2x - 3y ≤ 18
<span>To do this, we have to setup equations and then use substitution to get like terms.
c=children, s=students, a=adults
For total cost: 5350 = 5c + 7s + 9a
Total capacity: 750 = c + s + a
Data given: (.5)(c + s) = a
Now, rearranging the data given equation for (c+s) gives us (c+s)= 2a. Using this and substituting into the total capacity equation for (c+s) will allow us to find a: 750 = 2a + a = 3a which gives us a = 750/3 = 250.
Next, we set a = 250 in total cost and data given equation to get the following:
Total Cost: 5350 = 5c + 7s + 2250 which gives 3100 = 5c + 7s
Total Capacity: 750 = c + s + 250 which gives 500 = c + s
Rearranging total capacity to solve for s: s = 500 - c
Plugging that expression for s into total cost gives us: 3100 = 5c + 7(500-c) = 5c - 7c + 3500.
Solving for c gives us 400 = 2c . Total number of children is c = 200.
Total number of students is s = 750 - 200 - 250 = 300.</span>

Answer:
19.93
Step-by-step explanation:
If you do 132.89 x 85% you would get 112.9565. You would round the first five up to a six and then subtract that by the original price. 132.89-112.96. Giving you the answer of 19.93.
Answer:
A = 30 ft^2
Step-by-step explanation:
The area of a triangle is given by
A = 1/2 bh
A = 1/2 (12)*5
A = 30 ft^2
