Answer:
y=5-3x
Step-by-step explanation:
The answer is 40 the answer is 40
Answer:Option (ii) is correct i.e. 20mph and 24mph
Step-by-step explanation:
Let us assume that the two riders are A and B
A B
Let speed of A be v mph then speed of B will be (v+4)mph
Time taken by A =3h Time taken by B=3-0.5= 2.5h
Since distance travelled by both is the same
Distance=
Dividing both sides by 0.5
v=
mph
i.e Speed of A=20mph
∴ Speed of B=20+4 =24mph
Simplifying
2ab + 4ab = 0
Combine like terms: 2ab + 4ab = 6ab
6ab = 0
Solving
6ab = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by '6'.
ab = 0
Simplifying
ab = 0
