Isolate the x. Subtract 20x from both sides, and add 15 to both sides
-5x (-20x) - 15 (+15) > 10 (+15) + 20x (-20x)
-5x - 20x > 10 + 15
Simplify. Combine like terms
-25x > 25
Isolate the x. Divide -25 from both sides. Note that when you are dividing by a negative number, flip the sign.
(-25x)/-25 > (25)/-25
x > 25/-25
x < -1
x < -1 is your answer

Answer:
200 actual miles
Step-by-step explanation:
Find the actual distance by multiplying 50 by 4, since there are 50 miles in 1 inch.
50(4)
= 200
So, there are 200 actual miles between the two cities.
With simple interest, you only earn 5.5% of the original $150 each year.
So after 4 years, your money will earn (5.5% x 4) = 22% of the original $150 .
22% of $150
= 0.22 x $150
= $33 .
Answer:
y = 9,958(0.972)^t
Step-by-step explanation:
From point to point, the difference in days is always constant (10 days), but the difference between estimated number of bees is not constant.
10000 - 7500 = 2500
7500 - 5600 = 1900
5600 - 4200 = 1600
4200 - 3200 = 1000
3200 - 2400 = 800
Therefore, the data don't fit a line.
From the other two options:
y = 9,958(0.972)^t
y = 0.972(9,958)^t
only the first one has sense, because its initial amount of bees is 9,958 (near to 10,000) and in the second option is 0.972.
