Answer:
a) and b) satisfied the condition of the given equation.
Step-by-step explanation:
Given: 
≠ 
+ 
Then,
≠ 
a) For a = 21, b = 4 and c = -2, then we have;
≠ 
≠ 
≠ 
≠ 
Therefore the condition of the given equation is satisfied.
b) For a = 1, b = 10 and c = 1, then we have:
≠ 
≠ 
≠ 
Therefore the condition of the given equation is satisfied.
Answer:
C
Step-by-step explanation:
3x + 3y = -x + 5y
3x + x = 5y - 3y
4x = 2y
Divide both by 2
2x = y
(1,2) when x=1, y=2
2(1)=2 is a true statement
(2,4) when x=2, y=4
2(2)=4 is a true statement
Answer:
c
Step-by-step explanation:a
add up 0, 1, 0, 2, 2, 1, 3, 0, 4, 0, 1, 2
The parts of the sum are 55 and 80.
Step-by-step explanation:
Let,
'x' be the smaller part and
'y' be the greater part of the number.
The sum is x+y = 135. --------(1)
The greater part y = x+25. ---------(2)
Substitute (2) in (1),
⇒ x+(x+25) = 135
⇒ 2x+25 = 135
⇒ 2x = 110
⇒ x= 110/2
x = 55
The smaller part is 55.
Substitute x=55 in (2)
y = 55+25 = 80
The greater part is 80.
