Common-Core Grade 10 - 10 Identifying solutions to inequalities

Substitute the value of x in the given inequality.
Assume that Hamed has to buy x number of packets to meet the requirements. Each packet contains 12 chocolates. Thus we can write the above problem in the form of linear inequality as: 12 * number of packets < 80 Or, 12x < 80 => 12x/12 < 80/12 (Dividing both sides with 12) => x < 20/3 Therefore the number of packets Hamed needs to buy to meet the requirement is 20/3. Or, x < 6.66 (as 20/3 is equal to 6.66)
Substitute the value of x in the given inequality.
If a = 12 7 – 12 < -5 -5 < -5
Valentina is correct as the solution to this will be 5. As we got with the value of l 3 + 4 × 5 > 22 7 × 5 > 22 35 > 22
Substitute the value of x in the given inequality.
If we select value of x = 14 13 < 2 × 14 13 < 28 So, this is the value of the equation.
Substitute the value of y in the given inequality.
Go through the answer choices one by one. Plug n = –4 into the inequality. n ≥ –4 –4 ≥ –4Plug in n = -4 It is true that –4 ≥ –4. So, n = –4 is a solution. Plug n = –11 into the inequality. n ≥ –4 –11 ≥ –4Plug in n = -11 It is false that –11 ≥ –4. So, n = –11 is not a solution. Plug n = –12 into the inequality. n ≥ –4 –12 ≥ –4Plug in n = -12 It is false that –12 ≥ –4. So, n = –12 is not a solution. Plug n = –6 into the inequality. n ≥ –4 –6 ≥ –4Plug in n = -6 It is false that –6 ≥ –4. So, n = –6 is not a solution. Only n = –4 is a solution.
Substitute the value of x in the given inequality.
