Answer:
y = 13.9
Step-by-step explanation:
It is given that
–5.7 + y = 8.2. -----(1)
Equation (1) is a linear equation in one variable.
LHS consists of a constant and a variable term
RHS consists of only constant term
<u>Find the value of y</u>
Solving the equation
-5.7 + y = 8.2
moving -5.7 to the RHS
y = 8.2 + 5.7
y = 13.9
Therefore the value of y = 13.9
-5.7 + y = 8.2
Answer:
60 ml of 40% saline and 90 ml of 15% saline
Step-by-step explanation:
We can call the amount of 40% solution x and the amount of 15% solution y.
x + y = 150 -- (1)
0.40x + 0.15y = 150 * 0.25 -- (2) --- 150 * 0.25 = 37.5
40x + 15y = 3750 (Multiply (2) by 100 to get rid of decimals)
15x + 15y = 2250 -- (3) (Multiply (1) by 15)
25x = 1500 (Subtract (3) from (1)
x = 60
y = 150 - 60 = 90
