A = oz of the solution A
b = oz of the solution B
The scientist knows that solution A is 45% salt and solution B is 95% salt. She wants to obtain 80 ounces of a mixture that is 65% salt.
a + b = 80
0.45a + 0.95b = 0.65*80
by solving the above system of equations you'll find····
a = 48 oz
b = 32 oz
~I hope this helped~
If it doesn't make since, I can try to switch up the wording ^^
1 to 4
Step-by-step explanation:
I'm guessing that is division?
4x^2/9z^3
Because the numerater and denomenater are = hence 1/1, 2/2, 3/3, 4/4 5/5, 6/6, 7/7, 8/8, etc. are all = to one
hope this helps :)
