10x - 3 = x + 2 + 2x - 1
10x - 3 = 3x + 1
-3x on both sides
7x - 3 = 1
-1 on both sides
7x - 4
(Check 7x - 4 by adding them all up to equal 10x - 3)
x + 2 + 2x - 1 + 7x - 4 = 10x - 3
combine liked terms
10x - 3 = 10x - 3
Answer:
D) 7x - 4
Answer:
29 miles
Step-by-step explanation:
a²+b²=c²
√a²+b² =c
√21²+20²=29
29miles
289 estimated is 290
7 estimated it 10.
290 times 10 is 2,900
Answer: 
Step-by-step explanation:
The formula to find the x-coordinate of a Midpoint, is:

And formula to find the y-coordinate of a Midpoint, is:

Given the Endpoint (2,5) and the Midpoint (3,4), we can idenfity that:

Therefore, in order to find the x-coordinate of the missing endpoint, we can substitute values into the formula
and solve for
:

To find the y-coordinate of the missing endpoint, we can substitute values into the formula
and solve for
:

Therefore, the missing endpoint is:
