Answer:
-60 and then -27 is the answer
Answer:
m ∠S = 43°
Step-by-step explanation:
Exterior angle = Sum of opposite interior angles
(6x)° = 77° + (2x + 3)°
6x = 77 + 2x + 3
6x - 2x = 77 + 3
4x = 80
x = 20
m ∠S = (2x + 3)° = 2(20) + 3 = 40 + 3 = 43°
The solution to the system of equations is x = -1 and y = -1
<h3>How to solve the following
system of equations?</h3>
The system of equations is given as:
2x + 3y = 1
5x - 4y = 14
Multiply 2x + 3y = 1 by 2.5
So, we have:
5x + 7.5y = 2.5
Subtract 5x + 7.5y = 2.5 from 5x - 4y = 14
So, we have
7.5y + 4y = 2.5 - 14
Evaluate the difference and the sum
11.5y = -11.5
Divide by 11.5
y = -1
Substitute y = -1 in 2x + 3y = 1
2x + 3(1) = 1
This gives
2x + 3 = 1
Subtract 3
2x = -2
Divide by 2
x = -1
Hence, the solution to the system of equations is x = -1 and y = -1
