3.20 divided by 16 is 0.2, so it costs 20 cents per ounce
Answer:
x ≤−9
Step-by-step explanation:
2x+15≤x/3
Simplify both sides of the inequality.
2x+15≤1/3x
Subtract 1/3x from both sides.
2x+15−1/3x≤1/3x−1/3x
5/3x+15≤0
Subtract 15 from both sides.
5/3x+15−15≤0−15
5/3x ≤ −15
Multiply both sides by 3/5.
(3/5)*(5/3x)≤(3/5)*(−15)
x≤−9

</span>(2x^2 - 5x + 4) Original Mathematical Expression
[2(7)^2 - 5(7) + 4] Plugging the value of x, 7 into expression.
There are parentheses, so that means we have to work in them.
There are exponents, so we have to do those first.
[2(49) - 5(7) +4] Exponents.
There is multiplication, that we can do, so we do that left to right.
[98 - 35 + 4] Multiplication.
There is no division.
There is addition and subtraction, so we do those left to right.
[63 + 4] Subtraction.
67 Addition.
Final Answer: 67
