3:5=x:50
Therefore 5 ×x = 50
x = 10
Therefore 3 × 10 = 30
therefore 30 blue pens
proof = 30 blue + 50 red= 3+ 5
therefore 80 = 8x
1580 I assume srry if it is incorrect
Let Issac work for x hours, and Ruby works 8 hours more than of Issac, so Ruby work for
hours.
And Svetlana worked four times of Ruby, therefore Svetlana worked for

And total hours they worked together is 136. That is

So Issac worked for 16 hours, Ruby worked for 24 hours and Svetlana worked for 24 times 4 equals 96 hours .
You're already given the slope, so the first step you must take is to find the y-intercept. To do this, you substitute the values of the coordinate M into y = 5x + c, with the x value substituting x and the y value substituting y. This gives us:
2 = (5 × 1) + c
2 = 5 + c
- 5
-3 = c
So now you know that the y-intercept is -3, you can see that your final answer must be the first option, y = 5x - 3.
I hope this helps!
To divide complex numbers, you multiply by the conjugate. The conjugate is when you change the sign between the two terms in the denominator. Therefore, the conjugate in this one is (3+i)
