Answer:

<em>I earned $856 on the first day</em>

Step-by-step explanation:

Let's call

x = earning on the second day

2x = earnings on the first day

3x = earnings on the third day

The total earnings are $2568, thus

x + 2x + 3x = 2568

Simplifying:

6x = 2568

Dividing by 6:

x = 2568/6

x = 428

I earned $428 on the second day.

2x = 2*$428 = $856

I earned $856 on the first day

FUNCTIONS HELP DONT SKIP
zavuch27 [327]

Answer:

Function

Step-by-step explanation:

This is a function.

The rule of a function is that every input has one output.

What that means is that for every x value, there is only one y value.

You can test this with the vertical lines method. If you draw vertical lines through the function, each vertical line should only intersect with the graph at a single point. If it intersects at two, it is not a function.

What is the value of x?<br> OA) 65°<br> B) 50°<br> OC) 80°<br> OD) 90°
Nata [24]

Answer:

Please mark be Brainliest and I hoped this helped!

x = 80°  

Step-by-step explanation:

These are both isosceles triangles, so the top 2 angles are both 65°. The last angle of that triangle is 180° - (65° + 65°) which is 50°. Then, the opposite of that angle is in the next triangle. It is also 50°. So the 2 base angles are both 50°, so x is 180° - (50° + 50°) which is 80°.
