Answer:
82 and 98.
Step-by-step explanation:
set up 2 equations
x+y=180
2x+16=180
you start by solving the second equation to find one of the angles.
180-16= 164
2x=164
164÷2= 82
x=82
since you've solved that equation, add in the missing variable to solve for the next one
82+y=180
180-82= 98
3. 5/12 * 4/9 = 5/27
4. x - 2 2/5 = 5 13/20
x - 12/5 = 113/20
x = 113/20 + 12/5
x = 113/20 + 48/20
x = 161/20 or 8 1/20
Answer:
D. Section A; students in this section scored between 1 and 10
Answer:
Step-by-step explanation:
You know that the formula to find the sum of a finite geometric series is:
Where is the number of terms, is the first term and is the common ratio ().
The steps to find the sum of the first 12 terms of the given geometric serie, are:
1. Find the common ratio "r". By definition:
Then:
2. Finally, knowing that:
You must substitute values into the formula.
Then you get:
Slope= rise/run
which is 4/2
4 decided by 2 is 2
so the slope is 2. also i LOVE ur pfp :)))
