Answer: The correct option is the first one.
Step-by-step explanation:
Let's define how to interpret each symbol:
x < a (x is strictly smaller than a, we graph this with an open circle at a, and an arrow to the left of a)
x > a (x is strictly larger than a, we graph this with an open circle at a, and an arrow to the right of a)
x ≥ a (x is larger than or equal to a, we graph this with a closed circle at a, and an arrow to the right of a)
x ≤ a (x is smaller than or equal to a, we graph this with a closed circle at a, and an arrow to the left of a)
In this case, we have the inequality:
x ≤ 15
Then to graph this we need a closed circle at 15, and an arrow to the left. The correct option is the first one.
Answer:
8
Step-by-step explanation:
The ratio is 3/2 boys/girls
if we call the expression as x there would be a total of 5x girls and boys
3x of this is boys
3x = 12 so x is 4 then 4×2 = 8 girls
Answer:
2 per balloon
Step-by-step explanation:
Dozen = 12
-6.9~ -6 is the whole number and 9/10 is the fraction. 9/10 equals 0.9
Start by laying out the 12.
The neighbors of 12 must be 11 and 10.
The neighbor of 11 must be 9, and the neighbor of 10 must be 8, and so on and so forth, until you get a unique arrangement.
