Answer:
6375 ≤ P < 6385
Step-by-step explanation:
When rounding to the nearest 10, the unit value is either rounded to 1 and added to the tens value (if value is greater than or equal to 5) or rounded to 0 (if less Than 5)
Hence, the lower limit of a number p which gives 6380 when rounded to the nearest ten would be 6375 ;
The upper limit of the number p in other to give 6380 when rounded to the nearest 10 will be 6384 (< 6385)

Answer:
WX = 33
(x, y) = (2, 10)
Step-by-step explanation:
The hash marks tell you WX is a midline, so has the measure of the average of the two bases.
WX = (PQ +SR)/2 = (27 +39)/2 = 66/2
WX = 33
__
The hash marks also tell you ...
PW = WS
y +4x = 18 . . . . . . substitute the given expressions
and also
QX = XR
2y +x = 22 . . . . . substitute the given expressions
__
If you solve the first equation for y, you get ...
y = 18 -4x
Substituting that into the second equation gives ...
2(18-4x) +x = 22
36 -7x = 22 . . . . . . . simplify
14 = 7x . . . . . . . . . . . add 7x-22 to both sides
2 = x . . . . . . . . . . . . divide by 7
y = 18 -4(2) = 10 . . . find y using the above relation
The values of x and y are 2 and 10, respectively.

My favorite "quick and dirty" way to solve a set of linear equations is using a graphing calculator. It works well for integer solutions.
Step 1) Divide 6 and 4 (the last 2 numbers) and bring everything else down
<em>6x^24x+2x+4</em>
Step 2) Place in parentheses
<em>(6x^24x)+(2x+4)</em>
Step 3) Figure out what you can take out of each parentheses.
**In the first one, you can take out 6x because both numbers have x and 6 is the largest number 6 and 24 can go into.**
**In the second one, you can only take out 2 because 2 is the largest number that goes into 2 and 4.**
Step 4) You will know you did it correctly when the parentheses match up
<em>6x(x+4) + 2(x+4)</em> <<< this is how it should look
Answer: <em>(6x+2)(x+4)</em>
The answer is C and brainliest answer please.
