Answer:
72 inches
Step-by-step explanation:
The perimeter is the sum of the outside "fence"
The side on the left that is not marked is 19-11 = 8
And the side on the top that is not marked is 17-10 = 7
Summing up the sides starting at 19 and going clockwise
19+17+11+7+8+10 =
72 inches
Y = 5x + 5
y - x = 5
You can use substitution to solve this system. Use y's expression (5x + 5) for y in the second equation to solve for x:
y - x = 5
5x + 5 + x = 5
6x + 5 = 5
6x = 0
x = 0
Substitute your value for x into one of the original equations to y:
y = 5x + 5
y = 5(0) + 5
y = 5
Finally, substitute both values into both original equations to check your work:
5 = 5(0) + 5 --> 5 = 5 <--True
5 - 0 = 5 --> 5 = 5 <--True
Answer:
x = 0
y = 5
