Answer:

$8r + 6s = 100$ --- (a)

$s = -2$ ---- (b)

Step-by-step explanation:

Given

Per ride (r) = $8

Per baseballs (s) = $6

Total = $100

Required

Represent using an equation

If 1 ride is $8.

r rides would be 8r

If 1 baseball is $6

s baseballs would be 6r.

So, total is:

$8r + 6s = 100$

Solving (b):

Value of s when r = 14

$8r + 6s = 100$

Substitute 14 for r

$8 * 14 + 6s = 100$

$112+ 6s = 100$

Solve for 6s

$6s = 100 - 112$

$6s = -12$

Solve for s

$s = -12/6$

$s = -2$

Find the length of X

nasty-shy [4]

Answer:

$x = 8\sqrt{2}$

Step-by-step explanation:

Leg = x

Hypotenuse = 16

$x\sqrt{2} = 16$

$x = \dfrac{16}{\sqrt{2}}$

$x = \dfrac{16}{\sqrt{2}} \times \dfrac{\sqrt{2}}{\sqrt{2}}$

$x = \dfrac{16\sqrt{2}}{2}$

$x = 8\sqrt{2}$
