Answer:

B. a + c = 216

5a + 3c = 902

Step-by-step explanation: This is the correct answer, because a represents adults and c represents children, so a + c = 216 and 216 represents the total number of people that the money was collected from. So, that would be correct for the first part of the system of equations. Next, 5a represents $5 for each adult, and 3c represents $3 for each child. While, 902 represents the total number of money collected at the park. Therefore the answer a + c = 216 5a+ 3c = 902 is the correct system of equations answer. Hope this helps ^-^.

I don't know what is between f(x) and g(x), so (for now) there are two posible answers:

1. $f(x)g(x) = f(x)\cdot g(x)$ - function multiplication:

$f(x)g(x)=(2x-3)\cdot(3x+8)=2x\cdot3x+2x\cdot8-3\cdot3x-3\cdot8=\\\\=6x^2+16x-9x-24=\boxed{6x^2+7x-24}$

2. $f(x)g(x)=f(x)\circ g(x)$ - function composition:

$f(x)g(x) = f(x)\circ g(x) = f\big(g(x)\big)=2(3x+8)-3=2\cdot3x+2\cdot8-3=\\\\=6x+16-3=\boxed{6x+13}$

A box of small crackers holds 4 equal servings. If there are 124 crackers in the box, how many crackers are in each serving?

kotykmax [81]

For this equation, we can simply divide the box's total (124) by 4 servings. 124/4 = 31. So, there is 31 crackers per serving.

5|2x - 3| + 4 = 9 How do you solve this

agasfer [191]

Answer:

x = 2, or x = -1

Step-by-step explanation:

If 2x - 3 is inside the parenthesis (), then the value of x is 2.

If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.

Solution 1

(10x-15) + 4 = 9

10x -11 = 9

10x = 20 -> x = 2

Solution 2 (Not 100% sure)

|10x -15| +4 = 9

10x + 15 +4 = 9

10x + 19 = 9

10x = -10 -> x = -1

Please correct me if I'm wrong.
