Answer:
$22.80
Step-by-step explanation:
16.20+p=39
subtract to get answer
Y= 3x + 1
If x is 2 we plug in 2 instead of x
The equation becomes y= 3(2) + 1
now you just solve
y= 6+1
y=7
One is 60, the other is 120. Imagine 3x equals 180. 60 is x, and 2x, or the bigger angle is 120.
Yes because when you turn into a decimal it's 7.2
The solution to the system is (2,-1)
To make sure plug in the ordered pair into the system of equations
-2(2) - 3(-1) = -1
-4 - (-3) = -1
-1 = -1
3(2) + 6(-1) = 0
6 + -6 = 0
0 = 0
This ordered pair works and is your answer
(2,-1)
