Answer:
Option D is correct.
y =6
Step-by-step explanation:
Given the system of equation:
.......[1]
.......[2]
Multiply equation by 12 in [1] we get;
.......[3]
Multiply equation by 12 in [2] we get;
.......[4]
Multiply equation [3] by 5 we get;
.....[5]
Multiply equation [4] by 4 we get;
.....[6]
Subtract equation [6] from [5] to eliminate x we get;
Divide both sides by 69 we get;
x = -4
Substitute the value of x in [3] we get;
Subtract 36 from both sides we get;
Divide both sides by -8 we get;
y = 6
Therefore, the value of y is 6
We need to convert 2 kilograms into pounds. First, we find how many pounds are in 1 kilogram.
There are about 2 pounds in one kilogram.
Then we multiply 2 pounds by 2 kilograms to convert the 2 kilograms into pounds.
2 * 2 = 4
So, the answer to this question is 4 pounds.
Answer:
3/10
Step-by-step explanation:
Because the fractions don't have the same denominator, the first step is to make them equal. Because the denominators here are 5 and ten, we can simplify 3/5 to 6/10. The next step is to subtract 3/10 from 6/10 to get 3/10. Because the question is asking what fraction of detergent is left, the answer is 3/10.
Answer:
C.) The relationship is proportional
Step-by-step explanation:
If D is true, then it is not proportional, constants of proportionality must not include multuplting or subtracting from anything.
