Answer:
(a)
(b)
1 pound of banana = $0.75
1 pound of grape = $2.00
Step-by-step explanation:
Given
Represent banana with b and grapes with g.
From the first statement, we have:
From the second, we have:
Solving (a): The equations
This has been solved above.
The equations are:
Solving (b):
--- (1)
--- (2)
Multiply (2) by 2
* 2
----- (3)
Subtract (3) from (1)
Substitute 0.75 for b in (2)

Answer:
Step-by-step explanation:
Tripple 2x+y=-2
6x + 3y = - 6 And 5x + 3y = -8
Subtract the second equation from the first to get
X = -14
Now that we have x, we need to determine y.
(2 x -14) + y = -2
-28 + y = -2
Hence, -28 + 2 = - 26
Now thats the difference, but because we are adding y to -28 to get -2, y has to be positive
Hence, y must be 26
X= -14, Y= 26
multiply everything by 3 then add it all up
1.25×3= 3.75
2.5×3= 7.5
1×3=3
7.5+3.75+3= 14
Hello!
In this case, you are looking for a value of K so the left side of the equation is equal to the right.
The left side of the equation is K (3x - 2), and the right is 4 - 6x. To get the left side to equal the right, you can set K = -2. This is because of the <u>distributive property</u>: a number just outside of the parenthesis can distribute to everything in the parenthesis like so:
-2 (3x - 2) = (-2 * 3x) - (-2 * -2) = -6x + 4
Therefore, your answer is K = -2.
Hope this helps!
(Side note: a better way to do this would be to divide both sides by 3x - 2)
