Answer:

Step-by-step explanation:

4x + 3y = -1         --------------(i)

3x - 9y = 33        -------------(ii)

multiply equation (i) by 3

(i)* 3     12x + 9y = -3

(ii)       <u>   3x - 9y = 33</u>

add,       15x = 30

                 x = 30/15

                 x = 2

Put x =2 in Equation (i)

4*2 + 3y = -1

8 +3y = -1

     3y = -1-8

     3y = -9

       y = -9/3

       y= -3

An employee earns $200 for 14 hours work. Assuming he is paid by the hour, how much will this employee earn in 35 hours?
bezimeni [28]
If an employee earns 200 dollars for 14 hours work, that means this person gets approximately 14 dollars and 29 cents per every hour.

Thus, in 35 hours, you can multiply 14.29 by 35 to get about 500 dollars.

In 35 hours, the employee will earn 500 dollars.

Please help me with the last question
Greeley [361]
You'd solve this by creating the equation
20 + 6x - 1 + x + 14 = 180
33 + 7x = 180
- 33
7x = 147
÷ 7
x = 21
(because angles in a triangle add up to 180°)
And then you'd substitute in the value of x, so
6 × 21 = 126
126 - 1 = 125° = Angle A
21 + 14 = 35° = Angle C
I hope this helps!
