Let's take this problem step-by-step:

Let's first set up some variables:

c: # of children
a: # of adults

Let's examine the information given:

Elevator can hold a maximum of 1500 pounds

⇒ average child is 75 pounds

⇒ average adult is 150 pounds

⇒ therefore: $75c + 150a\leq 1500$

Elevator can fit no more than 14 people

⇒ therefore: $c + a \leq 14$

Let's graph the equations:

$75c+150a\leq 1500\\c+a\leq 14$

⇒ look at the image attached

The point at which the two graphs intersect:

⇒ is the solution that represents the amount of children and adults and

their combine weight

With the horizontal axis being the # of children and vertical axis being the # of adults:

⇒ the solution is 8 children and 6 adults

Answer: 8 children and 6 adults

Hope that helped!

What is the length of side x? (possibly use similar triangles)

Law of Sines

$\frac{sin(A)}{a} = \frac{sin(B)}{b}$

$\frac{sin(90)}{14.6} = \frac{sin(45)}{x}$

Cross multiply

x*sin(90) = 14.6sin(45)

x = 14.6sin(45)

x = 10.3

Answer:

1) 12

2) c=-25

3) x = -16 2/3

Step-by-step explanation:

1) ..........................

6*(4-10+8) =
6*(- 6+8) =
6*2=
12

2) ..........................

34 + 2c = -16
2c = - 16 -34
2c = -50
c = -50/2
c=-25

3) ..........................

40 = -3x - 10
40+ 10 = -3x
-3x = 50
x = 50/-3
x=-16 2/3

Answer:

Step-by-step explanation:

We have to multiply it by two because they have us 2 numbers for the legs, we use the Pythagorean theorem thing, but we have to basically add them, or we can multiply y 2(since they are the same number). Anyways $18\sqrt{2} (2)= 36\sqrt{2}$
