Answer:
y = -6
x = 1
Step-by-step explanation:
-x + 2y = -13
-x - 2y = 11
Sum the equations:
-x -x = -2x
+2y - 2y = 0
-13 + 11 = -2
then
-2x = -2
x = -2/-2
x = 1
from the first eq.
-x + 2y = -13
-1 + 2y = -13
2y = -13 + 1
2y = -12
y = -12/2
y = -6
check:
from the second eq.
-x -2y = 11
-1 -(2*-6) = 11
-1 -(-12) = 11
-1 + 12 = 11
60% is the answer you are seeking.
Answer:
x=6
Step-by-step explanation:
Step 1:
Subtract 3x from both sides:
4x + 8 - 3x = 3x + 14 - 3x
x + 8 = 14
Step 2:
Subtract 8 from both sides:
x + 8 - 8 = 14 - 8
x = 6

Answer:
Step-by-step explanation:
Perimeter = 20.56mm
Given the perimeter, find the diameter
= 20.56
D = 20.56 ÷
D = 6.54 mm
Perimeter of the Semicircle = half the circle arc + the straight line (Diameter)
Semicircle = 0.5(20.56) + 6.54cm
Semicircle = 16.83mm
