171 because first u minus 180 from 123 then you times that by 3
2x+3y=6
3y=-2x+6
3y/3=-2x+6/3
Y=-2/3x+2
The hundreds that must be added to 69,000 to make 4,000,000 is 39.
<h3>What does division mean?</h3>
Division is a mathematical operation that involves dividing a number into equal parts using another number. The sign used to denote division is ÷.
<h3>How many hundreds must be added to 69,000 to make 4,000,000?</h3>
In order to determine the answer, divide 4,000,000 by 100,000: 4,000,000 / 100,0000 = 40.
Because 69,000 has already been ran, subtract 1 from 40. This gives 39.

Answer:
Step-by-step explanation:
We will let the x coordinates be the temp and the y coordinates by the number of chirps. Our coordinates then will look like this:
(60, 84) and (85, 184). If this is linear, then first we will find the slope of the line which will tell us, in the context of this problem, how many chirps a cricket gives per 1 degree of temp increase.
The slope formula is:
and filling in our numbers:
This means that for every 1 degree temp increase, a cricket will give 4 chirps. That's the m value in y = mx + b. Now we will pick one of the coordinates, doesn't matter which one, and use those x and y values in the point-slope form of a line to get the equation. I will choose (60, 85), just because. Using the other point will give you the exact same line equation, I PROMISE!
Using 85 as y1 and 60 as x1 in
y - y1 = m(x - x1) gives us
y - 85 = 4(x - 60) and
y - 85 = 4x - 240 and
y = 4x - 240 + 85 and
y = 4x - 155
