Answer:
Step-by-step explanation:
Let the number of ounces of
A = x
B = y
A scientist has two solutions, which she has labeled Solution A and Solution Each contains salt. She knows that Solution A is 40% salt and Solution B is 55% salt. She wants to obtain 90 ounces of a mixture that is 45% salt. How many ounces of each solution should she use?
Our system of equations is given as
x + y = 90.... Equation 1
x = 90 - y
40% × x + 55% × y = 45% × 90 ounces
0.4x + 0.55y = 40.5....Equation 2
We substitute 90 - y for x in Equation 2
Answer:
i don't know maybe D. 2 and 3
Answer:
The answer is 63°
Step-by-step explanation:
The lines intersect so opposite angles are congruent.
Answer:
Distribute
When you have an equation like this, distribute first and then add or subtract like terms to solve for x.
Hope this helps!!
