Perimeter = 2l + 2w
perimeter = 2(90) + 2(30)
perimeter= 180+60
perimeter= 240 ft
Answer:
x = 4
y = -1
z = 3
Step-by-step explanation:
Let 1st number = x
Let 2nd number = y
Let 3rd number = z
x+y+z=6
x+y=z
x=z+1
(Apply Simultaneous Equations)
Hence:
z+z=6
2z=6
z=6/2
z=3
Now:
x+y=3
x=3+1
x=4
Now:
4+y=3
y=3-4
y=-1
Answer:
23
Step-by-step explanation:
32=3x-4+x
32=4x-4
+4 +4
36=4x
/4 /4
9=x
Larger #= 3x-4
Larger #= 3(9)-4
Larger #= 27-4
larger #= 23
A line that is parallel to another line will have the same slope as the original. A line that is perpendicular to another line with have a slope that is the opposite reciprocal of the original.
Original: -3 / 1
Parallel (same): -3 / 1
Perpendicular (opposite reciprocal): 1/3
Hope this helps!! :)
Answer:
No solution
Step-by-step explanation:
-y = -1
-51 - 3y = -15
-3y = -15 + 51
-3y = 36
y = -12
y = 1
y = -12
No solution
