Let c be children and a adults.
3.5c + 7a = 1771 (the total revenue is equal to the amounts made off of people)
c + a = 331 (total number of people)
The second formula becomes a = 331 - c. This can be substituted into the first formula.
3.5c + 7(331 - c) = 1771 = 7*331 - 3.5c = 1771. 7*331 = 2317, so 3.5c = 2317 - 1771 = 546.
546/3.5 = 156 = c (number of children).
c + a = 156 + a = 331 => a = 331 - 156 = 175 (number of adults).
There are 156 children and 175 adults
Answer: "less than" = subtract ( x - y )
So in this case its is 5-9 = -4 or 9-5=4.
Answer:
Altogether, 3 less than 5 times a number is 5n−3 .
Step-by-step explanation:
Answer:
B) Ill only
Step-by-step explanation:
This is because y = arcsin x can be re-written as sin y = x, We then differentiate sin y = x implicitly with respect to z to obtain
d(siny)/dz = dx/dz
(cosy)dy/dz = dx/dz
dy/dz = (1/cosy)dx/dz
Answer:
A. 
Step-by-step explanation:
<h3>Step 1: Definition</h3>
The parent function of 
is translated to the left when 
is positive in the transformation 
.
If is negative, the graph translates towards the left with the distance equal to the value of .
<h3>Step 2: Implementation</h3>
Here the graph moved 3 units towards the right. This means that is negative and has the value of 3.
So, plugging that into the parent function for translation, the function becomes:
