Answer:
All three chose a valid first step toward solving the equation.
All approaches are algebraically correct
The expression 8(-3) represents the recession of the coastline after 8 years if the coastline recedes 3 centimeters each year. 8(-3)=-24. So, the coastline's new position is 24 centimeters farther inland than it was 8 years ago.
answer= 24
Answer:
Options D, E, and F
Explanation:
Since the angles of triangle EFG are 30-60-90, this is a special triangle,
So, first, a diagram of the triangle is given below:
Next, we show the options that are true:
Option D

Option E

Option F

Options D, E, and F are true about triangle EFG.
10 / 0.1 = 10,000/x......10 samples to 0.1 lb = 10,000 samples to x lbs
cross multiply
(10)(x) = (10,000)(0.1)
10x = 1000
x = 1000/10
x = 100 lbs <====
