So, if the legs are a and b and the hypothuse is c then
a²+b²=c²

the distance bewteen the points is the hyptohuse

the legs are the distances between th x and y values

so
(7,11) and (-1,5)
distances between the x values are 1 leg
that is from 7 and -1, a distance of 8 units

distances betweeen the y values are the other leg
that is from 11 to 5
that is 6 units

a²+b²=c²
8²+6²=c²
64+36=c²
100=c²
sqrt both sides
10=c
the distance between them is 10 units

How to estimate 2 5/6, first one to answer will be marked brainliest
RideAnS [48]

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.

What does m equal in this equation 5m – 8 = 3m + 8 for m.
Radda [10]

5m-8=3m+8

(Plus the '8' to both sides)

5m=3m+16

(Subtract '3m' from both sides)

2m=16

(Divide by 2)

m=8
