Answer:
Hence amount of Alana's donation is $4.5.
Step-by-step explanation:
Amount of Alana's donation = x
Her grandmother agreed to add $4.00 to the amount Alana earned.
So new amount of money = (x+4)
She gives only half of the sum which is (x+4)/2.
She gave her $4.25 so both values must be equal.
4
3y - 4 + 2y
0 = 3y - 4 + 2y
4 + 0 = 3y - 2y
4 = y
y = 4
is this what you want ?
a
Answer: Add the equations to eliminate k
Adding the equations, you get 2b=18, which you can solve for b. Afterward, you can substitute this value of b back into either equation to solve for k.
Simplified expression:
If x = -1, the value of the expression is:
