Answer:
D.
Step-by-step explanation:
pi is not a rational number.
decimals is also not a rational number.
therefore the answer is D.
Answer:
y=4,x=1
Step-by-step explanation:
4x+y=8
x+y=5
subtract equation 2 from equation 1
3x + 0=3
3x=3
divide both sides by 3
x=1
substitute for x=1 in equation 2
x+y=5
1+y=5
y=5-1(collecting like terms)
y=4
From the equation, we can tell that left side of the equation has to be less than or equal to 6 in order for the equation to be true.
So first, let’s try n=0.
Plug it in: 2(0)=0 and since 0 is less than 6, it makes the equation true.
Next, let’s try 1. 2(1)=2. This also makes the equation true.
Next, let’s do n=3. 2(3)=6. So this also makes the equation true.
So the answers are:
n=0 , n=1 , and n=3

Given Data : Length = (7p - 10q) and Breadth = (2p - 9q)
Calculation :
⟹ Perimeter = 2(Length + Breadth)
⟹ Perimeter = 2(7p - 10q + 2p - 9q)
⟹ Perimeter = 2(9p - 19q)
⟹ Perimeter = <em>18p - 38q centimetres</em>
- <u>Answer : 18p - 38q centimetres</u>
