Cos=(adjacent/hypotenuse)
So the answer will be cos(16/20) or cos(4/5) both will give u the same answer
I hope it helps
108-271+215-_____=-103
Im going to combine the first thee numbers and replace the blank with a variable, lets use x.
52 - x=-103
now I am going to subtract 52 on both sides to get the variable alone
-x=-155
Im going to multiply both sides to eliminate the negitive in the variable
x=155
If you want to check just plug 155 into the blank
108-271+215-155=-103
-163+215-155=-103
52-155=-103
-103=-103
so after checking work the blank is equal to 155.
Answer:
The y-intercept would be 7
The slope would be -1 or -1/1. They are both the same thing.
The slope is the number which is located directly to the left of the variable (the variable in this case is x, but in other situations it could be a totally different letter).
3 3/4 - 2 1/3
get a common denominator of 12
3 3/4 * 3/3 = 3 9/12
2 1/3 * 4/4 = 2 4/12
3 9/12 - 2 4/12=
1 5/12
Answer: they ate 1 5/12 pints
