Answer:
x=7
Step-by-step explanation:
x/3 + x/6 = 7/2
Multiply each side by 6 to clear the fractions
6(x/3 + x/6) = 7/2 *6
Distribute
2x +x = 21
Combine like terms
3x = 21
Divide by 3
3x/3 = 21/3
x = 7
Perimeter is adding up all of the sides
the top and bottom are 3 and the left and right 10
so top (3)+ bottom (3)+ left (10)+ right(10)
3+3+10+10= 26
So your answer is c 26units
3r<= 4r - 6
4r - 6 >= 3r
r >= 6
solutions r >= 6
