Answer:
x = 10
Step-by-step explanation:
Perimeter of a triangle = the sum of the three sided of the triangle.
In an isosceles triangle, there are two equal sides and a base.
Perimeter = ( 3x - 6) + (3x - 6) + x
58 = 7x - 12
58 + 12 = 7x
70 = 7x
![\frac{70}{7} = \frac{7x}{7}](https://tex.z-dn.net/?f=%5Cfrac%7B70%7D%7B7%7D%20%3D%20%5Cfrac%7B7x%7D%7B7%7D)
10 = x

Answer:
6 or 8
Step-by-step explanation:
For every cycle of picks Sweet T has she gets 2 orange and 5 green. 2+5=7. To find how many cycles there are divide 25/7= 3 Remainder:4. To mind how many orange then do 3 times 2(2 for each cycle)=6.
The reason I say 6 or <u><em>10</em></u> is that you could add 2 oranges from the remainder to the total # of oranges.
3k+16=5k
-3k -3k
__________
16=2k
/2k /2k
_________
8=k
