Answer: A.
The reason is because if you're adding a negative to a number, it's subtraction, which is in the expression.
Answer:
x=22+8 and x+22=8nd 8=22_x
Answer: When graphing a linear inequality on a number line, use an open circle for "less than" or "greater than", and a closed circle for "less than or equal to" or "greater than or equal to". Graph the solution set of: -3 < x < 4 The solution set for this problem will be all values that satisfy both -3 < x and x < 4.
Step-by-step explanation:
Let n be the first even integer, and n+2 will be the second even integer. (Why? Think 2 and 4, 2+2=4. This is the case for every consecutive even integers).
n + 3(n+2) = 54
n + 3n + 6 = 54
4n = 48
n = 12, n+2 = 14
The answer is C, because to find IQR you have to find the difference (subtract) of the first and third quartile
