Answer:
10
Step-by-step explanation:
-2+(-3)*(-8+4)
-2+(-3)*(-4)
-2+12
10
Step 1: Simplify both sides of the inequality.
10x+20<40
Step 2: Subtract 20 from both sides.
10x+20−20<40−20
10x<20
Step 3: Divide both sides by 10.

Answer: The answer is (B) They show direct variation because y=x+2 and 10-5=12-7.
Step-by-step explanation: We are given two points (5 7) and (10, 12) and we are to select the correct statement about the two given points.
Since we have
7 = 5 + 2 and 12 = 10 + 2, so we can directly say that the equation of the line passing through the two points will be
y = x + 2.
Since we can directly find the relation between x and y, so we can say that they show direct variation because y=x+2 and 10-5=12-7.
Thus, the correct option is (B).
<span>Given data shows that 1/3 time less time for fans to exit a game as it does for them to enter and find their seats.
Ingress for the stadium = 3,000 fans per hour
Ingress rate = (1 - 1/3) x Egress rate = 2/3 Egress rate
Egress rate = 3/2 ingress rate = 3/2 x 6,000 = 9,000 fans per hour</span>
