-97 = 3x - 12x - 16
Simplify more
-97 = -9x - 16
Add 16 to both
-81 = -9x, x = 9
Solution: x = 9

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
If 5 is the base, 3(x-1) is the argument:
3x-1=5²
3x=26
x=26/3
If 5 is with 3x-1, that is, if 5(3x-1) is the argument, and the base is 10:
5(3x-1)=10²
3x-1=20
3x=21
x=7
Answer:
Your answer is B.
Step-by-step explanation:
4 x 2 = 8
I know this because 12 / 6 = 2.
Therefore, Sense it is divided by two, you multiply the 4 by 2.
