Answer:
Multiply by 3 -> 3(x - y = 6)
Step-by-step explanation:
Cuz since the 2nd is positive 3y
u need a negative 3y to get rid of it
3(x - y = 6)
2x + 3y = 7
3x - 3y = 18
2x + 3y = 7
5x/5 = 25/5
x = 5
5 - y = 6
-5 -5
-y/-1= 1/-1
y = -1
(5,-1)

<h2>100πcm².</h2><h2>None of the options is correct</h2>
Step-by-step explanation:
Total surface area of a cone
= 
Since the diagram is half of a cone, its surface area will be 
r = radius of the cone
l = slant height
From the diagram diameter of the cone = 16m;
r = 16/2 = 8m
l = 17m

Running = 2/3
Swimming = 5/6
5/6 - 2/3 = 5/6 - 4/6 = 1/6
Answer : She spent 1/6 hour longer swimming than running.
Answer:
$151.2
Step-by-step explanation:
To find the price after the tax is implemented,
set a relationship x/140=8/100 (8/100) basically means 8%.
cross multiply (140)(8)=1120. Then divide it by 100x, you get $11.2.
But that's just 8 percent of the total amount. So you need to add onto the original price, 140+11.2=$151.2.
