Assuming M is midpoint of RS
the midpoint formula is
x term of the midpoint is average of the x value of the 2 points
y term of the midpoint is average of the y value of the 2 points
if R is (x,y)
S is (6,1)
x value of midpoint is 4
x value of S is 6
x value os R is x
so
average of x and 6 is 4,
(x+6)/2=4,
x+6=8,
x=2
y value of midoint is 2
y value of S is 1
y value of R is y
average of 1 and y is 2
(y+1)/2=2
y+1=4
y=3
the midpoint is (2,3)
Answer:
5 centimetres = 1 kilometre
Step-by-step explanation:
First add up the distances measured on the map.
1.1+4.8+2.2+3.4=11.5 cm
Based on this, since the number of cm is greater than the number of km, we can figure out that each cm should not be multiplied to get the km, so we can eliminate the first two answers.
Next write an equation to represent finding the scale
x=scale
11.5=2.3x
Now solve for the scale
11.5/2.3=2.3x/2.3
5=x
Therefore the scale is 5 centimetres = 1 kilometre

I hope I was fast enough ^^
Answer:
x = 15
Step-by-step explanation:
the 2 angles are a linear pair and sum to 180° that is
8x - 3 + 4x + 3 = 180
12x = 180 ( divide both sides by 12 )
x = 15
Answer:
x<2 is your answer
Step-by-step explanation:
-2x+4>-4x+8
subtract each term by 8
-2x+4-8>-4x+8-8
add both side by 2x
-2x+2x-4>-4x+2x
-4>-2x
dividing both term by -2
-2x/-2<-4/-2
x<2
