Answer:
The simplified answer would be 7m+63. You would have to solve for the variable.
Step-by-step explanation:
Answer:
An equation contains an equal sign so -20 is not an equation, I think it's a typing error
Answer:
If your saying estimate this number in a decimal without calculators I think I might be able to help as illustrated below:
Step-by-step explanation:
2 5/6 shows that the whole number will be a 2. The 5/6 is a decimal below one as it is not one whole fraction. This means that we have to estimate the value of 5/6 and add that value to the number 2. 1/3 is a common fraction that is equal to about 0.33. This is because 0.33 + 0.33 + 0.33 is almost 1, which means 1/3 of one is indeed equal to 0.33.
<u>This means we divide 0.33 by 2, because that would be equal to (1/3)/(2), or 1/6. </u>0.33/2 seems like it would be 16.5. 16.5 * 5, as in 5/6, would be 82.5.
I would then say that the estimate of 2 5/6 is 2.83.
-6 + 5
= -1.

Using your approximate y-intercept on the line of best fit, your equation would be y=11/7x + 3.
We find the slope by choosing two points that are on the line:
(9, 18) is easy to spot; and (2, 7) is fairly easy to spot as well. The formula for slope is:
m=y₂-y₁/x₂-x₁
m=7-18/2-9 = -11/-7 = 11/7
Slope intercept form, y=mx+b, has the slope and the y-intercept. Plugging those in we have y=11/7x+3.
