Answer:
x≥4
Step-by-step explanation:
_6≥10+4x
group like terms
4x≥10+6
4x≥16
divide both side by 4
4x\4≥16\4
x≥4
the constant of proportionality
Step-by-step explanation:
proportional relationships are relationships between two variables where there are ratios equivalent. another way to think about them is that in a proportional relationship that one variable is always constant value times the other that constant is known as the constant of proportionality

= 3 Multiply both sides by 2
-4 + x = 6 Add 4 to both sides (to cancle out the -4)
x = 10
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.
