Let
x-------> the amount of 
solution
y--------> the amount of 
solution
we know that
so
-------> equation A
-------> equation B
substitute equation A in equation B
find the value of y
therefore
The student need 
of solution and 
of solution
<u>the answer is</u>
A) The percent values were written incorrectly in the equation
B) The amount of 7% solution should be written as 1 – x, not x – 1.
Answer:
Step-by-step explanation:
θ = 228° = (228°)×(π/180° radians/degree) = 228/180 radians
= 19/15 radians
≈ 1.266...(repeating) radians
Your question would be clearer if written as "What is 145% of 6000?"
1.45(6000) = 8700
