Answer:
$1470
Step-by-step explanation:
sneakers : boots
15 : 19
15 cost sneakers
------ = -------------------
19 570
using cross products
15 * 570 = 19 * sneakers
8550=19 * sneakers
divide by 19
8550/19 = sneakers
sneakers = 450
total cost = 2* sneakers + boot
total cost = 2 * 450 + 570
total cost = 900 + 570
total cost = 1470

Answer:
x = 0
, y = 7/6
Step-by-step explanation:
Solve the following system:
{18 y - 12 x = 21
6 x - 9 = -9
In the second equation, look to solve for x:
{18 y - 12 x = 21
6 x - 9 = -9
Add 9 to both sides:
{18 y - 12 x = 21
6 x = 0
Divide both sides by 6:
{18 y - 12 x = 21
x = 0
Substitute x = 0 into the first equation:
{18 y = 21
x = 0
In the first equation, look to solve for y:
{18 y = 21
x = 0
Divide both sides by 18:
{y = 7/6
x = 0
