Answer:
−5x − 7 < −22 and −5x − 7 ≥ −3 (the first one)
Step-by-step explanation:
22 is bigger than -5x and 7
-5x-7 is equal to or less than 22
and negative 3 is just negative 3
hope this helps!
Answer:
C. 120
Step-by-step explanation:
area of trapezoid = (base1 + base2)h/2
area = (10 cm + 6 cm) * 15 cm/2
area = 16 cm * 15 cm / 2
area = (240 cm^2)/2
area = 120 cm^2
Answer: B 192
Step-by-step explanation: In the picture attached, the complete question is shown.
The humpback whale traveled 2240 miles in 28 days. This makes the following rate:
rate = distance/time = 2240/28 = 80 miles/day
The distance traveled at this rate in 32 days is:
distance = rate * time = 80*32 = 2560 miles
The gray whales traveled 2368 miles in 32 days. Then, the humpback whales would have traveled 2560 - 2368 = 192 miles more than the gray whales.
C. 55 gallons because the formula for cylinder volume is V=pi•radius^2•height. So plug in the given values like in the pic below and then divide that by 231 to find the gallons
If d = rt, Then r = d/t
avg speed = 720/t
Therefore after subtracting penalty points, the function for score is:

For part 2 i will attach a picture.
Part 3)
Set s = 3 and solve for t
