For the first box on the left hand side, the answer is m < 1 + m < 2 = 180 as they are a linear pair

The first box in the right-hand column is "linear pair postulate" as its very similar to the previous line

The second box on the left-hand side is m < 1 + m < 2 = m < 2 + m < 3. Essentially we're doing replacements. Similar to how x+3 = 10 turns into 7+3 = 10 when we plug in x = 7

The second box on the right-hand side is "subtraction property of equality". We subtract "m < 2" from both sides to end up with m < 1 = m < 3

Two planes start flying towards each other simultaneously from two different cities. The distance between the cities is 960 mile

Eddi Din [679]

Answer:

The speed of one plane = 257.5 miles per hour

And speed of second plane = 332.5 miles per hour

Step-by-step explanation:

We have given,

Distance between two cities = 960 miles

Two planes are flying towards each other.

Let the speed of one plane be x.

Then,

Speed of second plane = x+75 {Following this "one of the planes' speed exceeds the other by 75 mph"]

After 1.5 hours they are still 75 miles apart.

i.e Relative distance between two planes = Relative speed of plane × Time

Here

relative speed = x + (x+75) , and relative distance left to cover = 960-75.

i.e

(960 - 75) = {x+(x+75)}×1.5

885 = (2x+75)×1.5

or $\frac{885}{1.5} =2x+75$

or 590-75 = 2x

or 515 = 2x

or x = $\frac{515}{2}$ = 257.5

Hence the speed of one plane = x = 257.5 miles per hour

And speed of second plane = (x+75) = 257.5 + 75 = 332.5 miles per hour

A parallelogram is translated 2 units to the right and 1 unit down and then rotated 90 degrees clockwise about the orgin. Does i

vazorg [7]

Yes because it is a square and if you rotate a square 90 degrees it will stay the same shape

Have a good day!
