Step-by-step explanation:
due to the rules of crossing lines and their angles, the 2 angles opposite of each other must be equal.
so,
7x + 7 = 112
7x = 105
x = 15
Since he lost 5 every month, it should be that the slope is -5, not 5, he is not gaining 5 every month
yint is 100 and slope is -5 would be correct
b=-5m+100
b=number of blocks he has after m months
It would be c because fe is a radius ba is a chord and ec isnt a line
The rate of change per year is 3 million per year.
Let x be your first alloy
2/5x+7/10(30-x)=1/2(30)
4x+210-7x=150
3x=60
x=20
So, you need 20 lbs of the first alloy, and 10 parts of the second to make 30 lbs of half iron and half silver alloy!
