Answer:
5.4
Step-by-step explanation:
To find the distance between each pair of points, we use the distance formula, which is:
d = 
So we have

When we plug in the values into the formula we get:
d = 
d = 
Answer:
C. Add 15 to both sides
Step-by-step explanation:
Given equation:
99x – 15 = 45
To solve:
<u>Step 1</u>: Add 15 to both sides:
⇒ 99x – 15 + 15 = 45 + 15
⇒ 99x = 60
<u>Step 2</u>: Divide both sides by 99:
⇒ 99x ÷ 99 = 60 ÷ 99
⇒ x = 60/99
⇒ x = 20/33
Y = x + 5....so we sub in x + 5 for y in the other equation
4x + y = 20
4x + x + 5 = 20
5x + 5 = 20
5x = 20 - 5
5x = 15
x = 15/5
x = 3
y = x + 5
y = 3 + 5
y = 8
solution is (3,8)
Given that:
Consider it is
instead of 10 on two places.
is between 3 and 4. So, Beau thinks a good estimate for
is = 3.5.
Solution:
To find
, Beau found 3² = 9 and 4² = 16.
He said that since 10 is between 9 and 16.
Since 10 is close to 9, therefore
must be close to 3. So, Beau's estimate is high.
Now,


Since, 10 lies between 9.61 and 10.24, therefore
must be lies between 3.1 and 3.2.

Therefore, the estimated value of
is 3.15.
