Perimeter of a triangle = all 3 sides added together
x + (x - 4) + (x - 4) = 19
3x - 8 = 19
3x = 19 + 8
3x = 27
x = 27/3
x = 9 <==
Answer:
n=1
Step-by-step explanation:
distribute
-6 times -8n is =48n
-6 times 6 =-36
8 times -4 = -32
8 times n =8n
rewrite equation
48n-36+-32+8n=-12
48n+8n-36-32=-12
56n-68=-12
add 68 on both sides
=56
56n=56
n= 1
Slowest- 5.665 because it is 5 so it will round up.
Fastest- 5.669 will also round up to the nearest hundredth which is 5.67
Answer:
y = (2x - 1)/3.
Step-by-step explanation:
2x - 3y = 1
2x - 1 = 3y
y = (2x - 1)/3.
