Answer:
C. 5
Step-by-step explanation:
Point R divides the line segment PQ internally. The x-coordinate of the point which divides the line segment in ration m:n internally can be calculated as:
Here, x1 is the x-coordinate of 1st point, x2 is the x-coordinate of 2nd point, x is the x-coordinate of point dividing the segment. We have all the values except x2. Using the given values in above formula, we get:
Thus the x-coordinate of point Q will be 5
The x-coordinate of Q is 5.
Answer:
Step-by-step explanation:
The given expression is :
x = 3 (y + w) -1
We need to find the value of w in terms of x and y.
Solving RHS of the given expression :
x = 3y+3w-1
subtracting both sides 3y.
x-3y = 3y+3w-1 -3y
x-3y = 3w-1
Add 1 both sides
x-3y+1=3w-1+1
3w=x-3y+1
Hence, the correct option is (c) " i.e. w = StartFraction x minus 3 y + 1 Over 3 EndFraction.
Answer:
A = 20% B = 36%
Step-by-step explanation:
35 in total bought
2/10 = who bought model A = 20%
16+9 = 25 => 9/25 who bought model B = 36%
This is the simplest expression
43 < t
you can make it more complex by putting the same operations on both sides of the expression
for example lets multiply (1- t ) on both sides
(1-t)43 < t(1-t)
foil both sides and you get
43-43t<t-t^2
this is still equal to your original expression 43<t
