If p=q, then p+s=q+s
Example:
p=2
2+s=2+s since p and q are the same
Answer:
y = -7, x = 2
Step-by-step explanation:
x+3y=-23 (eq 1)
-x+4y=-26 (eq 2)
eq1 + eq 2
7y = -49
y = -7
Sub y = -7 into eq 1
x+3(-7) =-23
x -21 = -23
x = 2

Answer:
3π units
Step-by-step explanation:
The full circumference of a circle with radius 2 is ...
C = 2πr
C = 2π(2) = 4π
The arc shown is 3/4 of the full circle circumference so is ...
3/4C = (3/4)(4π) = 3π . . . units
Answer: x= 0
Explanation
64 = 4^3
