The setup looks like this:
0.4(10) + 4x = 0.3(14)
the 14 is the total amount of acid added.
4 + 4x = 4.2
4x = 0.2
x = 0.05 or 5 % acid solution
Answer:
x = 5
Step-by-step explanation:
x + 4 = 9
x = 5

Answer:
i think it would be the x- axis
Add all parts shared 2+3+7=12
Therefore 1 part is 176,496÷12= $14,708.
This means:
Luc has 2 parts: $14,708×2=$29,416
Deborah has 3 parts: $14,708×3=$44,124
Melanie has 7 parts: $14,708×7=$102,956
To check add all values together. If it makes the total amount, then the share is correct. 29,416+44,124+102,956=$176,496
Answer:
y = -6
Step-by-step explanation:
To simplify this equation as much as possible, we have to get the variable y by itself.
To do this, we would do the inverse operation of subtraction and add 7 to the left and right side of the equation.
-7 + 7 + 5y = -37 + 7
The 7s cancel out on the left side because -7+7 = 0 and so we are left with,
5y = -30
Then we would do the inverse operation of multiplication and divide by 5 on the left and right side of the equation.
5y/5 = -30/5
y = -6
