The diagonals of a rectangle are congruent and bisect each other.

MW = HW = (1/2)(MT)

MW = HW = (1/2)(50)

MW = HW = 25

3x + y = 25
7x - 6y = 25

Multiply the first equation by 6.
Write the second equation below it.
Add the equations.

       18x + 6y = 150
  +      7x - 6y = 25
--------------------------
        25x        = 175

x = 7

3x + y = 25

3(7) + y = 25

21 + y = 25

y = 4

Answer: x = 7; y = 4

HELP ASAP NOW NOW NOW NOW!!! Suppose three riders rode a total of 182 miles.
Sav [38]

Answer:

14 miles

Step-by-step explanation:

Assuming each horse was only ridden once

then a total of 13 horses were ridden for a total of 182 miles

182 miles / 13 horses  = 14  miles  horse

Of course, if each horse was ridden more than once before being replaced the distance between replacements could be reduced.

Note that the fact that there were 3 riders is irrelevant.

kali has a 6 centimeter ladder and puts the base of the ladder 2 meters away from the tree how high into the tree will the lader
weqwewe [10]
I am going to assume ‘centimetre’ was a typo.

A^2 + B^2 = C^2

C^2 - A^2 = B^2

32 = B^2

Square root both sides

B = 5.7m high

The ladder will reach 5.7 meters high
