28 + 29 + 42 = 28 + 42 + 29 = 99
Commutative property: a + b = b + a
Answer:
2A/b
Step-by-step explanation:
A=1/2(b)(h)
2A=(b)(h) Multiply both sides by 2
2A/b=h Divide both sides by b
h=2A/b
Answer:
(5,-6) is a solution
Step-by-step explanation:
Given


Required
Tell whether (5,-6) is a solution
In (5,-6): x = 5 and y = -6.
Substitute these values in the given equations
becomes
