Answer:
17.27 or 17.267
Step-by-step explanation:
You can using any equation you want to solve for one of the variables. For instance, if you want to solve for x you turn one of the equations so y is by its self
<span>
2x + 3y = 5
4x - y =3
I am going to use </span>4x - y =3
-y = -4x + 3
y = 4x -3
Now you can substitute 4x - 3 for y in 2x + 3y = 5 and solve for x
2x + 3y = 5
2x + 3(4x - 3) = 5
I think she would have to divide 2/3 by 1/2. So you would do 2/3 x 2/1 and since 2/1 is equal to 2 the answer would be B

Answer 5 is , hey played it at an equal amount so there for the answer is a trick! (Answering question 6 rn)
Answer:
The answer is
<h2>12</h2>
Step-by-step explanation:
The above variation is written as
where k is the constant of variation
when y = 9
x = 4
We have
k = yx²
k = 9(4)²
k = 9 × 16
k = 144
So the formula for the variation is
when y = 1
Cross multiply
x² = 144
Find the square root of both sides
x = √144
x = 12
Hope this helps you.
