Answer:
b+8≥12.4
Step-by-step explanation:
Here, we want to select the correct option
From what we have here;
b ≥12.4-8
b ≥ 4.4
Looking at the range of values in the set
We can see that the smallest of values is 4.4
This tells exactly the correctness of the last option as the values of b are 4.4 or greater
Answer:
1.3inch
Step-by-step explanation:
X,y - two numbers (x > y)
(1) x + y = 67 ⇒ x = 67 - y
(2) x - 4 = 2y
subtitute (1) to (2)
67 - y - 4 = 2y
63 - y = 2y |add y to both sides
63 = 3y |divide both sides by 3
y = 21
subtitute the value of y to (1)
x = 67 - 21 = 46
Answer: 21 and 46.
Your answer will be the third option.
