Answer:
x= 11
y= -2
Step-by-step explanation:
8y + 27 =x
3(8y+27) + 7y =19
24y + 81 + 7y =19
31y + 81 =19
<u> -81 -81</u>
<u>31y</u> = <u>-62</u>
<u>31 31 </u>
y = -2
-x + 8(-2) = -27
-x - 16 = -27
<u> +16 +16 </u>
-x = -11
x= 11

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
Mark has 403 coins
Since he has 89 more than his sister, then you subtract 403 - 89 to get his sisters total, which is 314
You need to find what they have in total, so 403 + 314
The answer is 717
