Answer:
2.1
Step-by-step explanation:
You need to substitute the 11 for the x.
y = -8.9(11) + 100
y = -97.9 + 100
y = 2.1
If you add 645 + 738 it equals to 1383 and add 645 + 649 it equals to 1294. the sum of both is different.
Answer:
Step-by-step explanation:
Let the three numbers be x, y, z
So from the problem given we can get the equations as
:
x + y+z= 66
x=2y
z=1x/3
Now we will make equation 1 have only one variable using equation 2 and 3.
y=1x/2 since x=2y
Now using equations 1, 3 and 5 we will get
x+1x/2+1x/3=66
11x/6=66
x= 66*6/11
x= 36
y=x/2=36/2=18
z=x/3=36/3=12
Therefore:
x = 36
y=18
z=12
Take into account that x represents the number of decades after 1950. Moreover, consider that -0.5x is a decrease in the values of y, each decade.
Then, you can conclude that each decade, that is, every 10 years, the shoreline reduces 0.5 feet.
Hnece, you have:
The shoreline is reduced by 0.5 foot every 10 years
