275=25x+100 is the correct equation for the number of months it will take for wade to save $275
To find the circumference of a round object, you will take the diameter and multiply is by pi to get 78.5mm
Answer:
The line represents a direct variation function.
Step-by-step explanation:
This line would cross the point (0, 0) making it a direct variation function.
We know the line would cross (0, 0) because the slope of the line is 2/3 (change in y over change in x, so 4-2 over 6-3 which simplifies to 2/3). From the point (3, 2), we can use the slope to calculate backwards to the origin.
1) You add 72+89 which you get 161 and you divide by two and you get 80.5
2) you do the same thing 72+89+90=251
And you divide by three and you get ≈83.66
