Answer: option A is the correct answer.
Step-by-step explanation:
The given system of equations is expressed as
- 6x - 2y = 10 - - - - - - - - - - - - - - - -1
y = - 3x - 5 - - - - - - - - - - - - - - - -2
We would apply the method of substitution by substituting equation 2 into equation 1. It becomes
- 6x - 2(- 3x - 5) = 10
- 6x + 6x + 10 = 10
10 = 10
Therefore, the given system of equations has infinitely many solutions because we have the same constants on both sides of the equation. If we take any value of x and y that satisfies one of the equations, they would also satisfy the other equation.
It would b because p = -6 and q = the opposite which is 6.
B is another way. hope this helps
Question 3.) The square root of 64/100=0.08
Bucket of lemons picked by Keith =
Bucket of lemons picked by Sally =
We have to determine the more buckets Sally picked.
The more buckets which Sally picked is determined by subtracting the bucket of lemons picked by Keith from bucket of lemons picked by Sally.
More buckets picked by Sally
=
The LCM of 5 and 15 is 15.
=
=
Therefore, Sally picked more bucket of lemons then Keith.
