Well, I Don't See The Answer Choices, But The Next Step Is Most Likely To Subtract 8 From Both Sides.
Answer:
8lb of the cheaper Candy
17.5lb of the expensive candy
Step-by-step explanation:
Let the cheaper candy be x
let the costly candy be y
X+y = 25.5....equation one
2.2x +7.3y = 25.5(5.7)
2.2x +7.3y = 145.35.....equation two
X+y = 25.5
2.2x +7.3y = 145.35
Solving simultaneously
X= 25.5-y
Substituting value of X into equation two
2.2(25.5-y) + 7.3y = 145.35
56.1 -2.2y +7.3y = 145.35
5.1y = 145.35-56.1
5.1y = 89.25
Y= 89.25/5.1
Y= 17.5
X= 25.5-y
X= 25.5-17.5
X= 8
Answer:
Step-by-step explanation:
<u>Given expression:</u>
<u>This is undefined when the denominator is zero:</u>
Correct choice is B
Answer:
B
Step-by-step explanation:
With a given parallel line and a given point on the line
we can use the point-line method: A(x-x0)+B(y-y0)=0
where
Ax+By=k is the given line, and
(x0,y0) is the given point.
Here
A=1,B=2,k=7.
(x0,y0)=(a,0)
=> the required line L is given by:
L: (x-a)+2(y-0)=0
on simplification
L: x+2y=a
