Answer:
Ryan, a consumer electronics salesperson, earns a base salary of $1,800 per month and a commission of 8% on the amount of sales he makes.
Step-by-step explanation:
Monday = - 2.1 Celcius
Tuesday = 15.2
Wednesday = 5
Thursday = - 4.6
Friday = 0
What was the average temperature for the first week in December?
The average temperature = (- 2.1 + 15.2 + 5 - 4.6 + 0)/5 = (20.2 - 6.7)/5 = 13.5/5 = 2.7°C
Answer:
This system has one solution (x=2 and y=2), then the answer is A.
Step-by-step explanation:
The system of equations is:
(1)
(2)
Let's multiply the first equation by 2 and subtract it to the second equation
Using this value in (1) we can find y.
Therefore, this system has one solution (x=2 and y=2), the answer is A.
I hope it helps you!
Step-by-step explanation:
Let a, b, c be the measures of the interior angles and x, y, z be the measures of the exterior angles of the triangle. Where x and adjacent to a, y is adjacent to b and z is adjacent to c.
By interior angle sum postulate of a triangle:
a + b + c = 180°... (1)
Therefore, by remote interior angle theorem:
x = b + c.... (2)
y = a + c..... (3)
z = a + b.... (4)
Adding equations (2), (3) & (4)
x + y + z = b + c + a + c + a + b
x + y + z = 2a + 2b + 2c
x + y + z = 2(a + b + c)... (5)
From equations (1) & (5)
Thus, the sum of exterior angles so formed is equal to four right angles.
Proved.
