Answer:
y=24
Step-by-step explanation:
4y+7+3y+5=180
7y=168
y=24
Answer:
(2,-1)
Step-by-step explanation:
Multiply first equation by 2:
10x + 2y = 18
Subtract the second equation from this so that the 2y terms cancel:
10x - 3x = 18 - 4
7x = 14
x = 2
Plug into first equation to find y:
5(2) + y = 9
10 + y = 9
y = -1
The answer is (2,-1)
Answer:
720 degrees =
or 0.785 radians.
Step-by-step explanation:
Given:
The angle in degrees in given as 720°
We need to convert this to radians.
Now, we know that, the relation between degrees and radians is given as:
180 degree = π radians
Therefore, using unitary method, the value of 1 degree can be calculated.
∴ 1 degree = 
Now, the value of 720 degrees can be calculated by multiplying the unit value and 720. So,

Hence, the measure of 720 degrees in radians is
or 0.25π radians or 0.785 radians.
