2xtimes 10 times 2
Answer:
Option B is correct

Step-by-step explanation:
Given that:
and
are supplementary.
prove that: 
It is given that:
and
are supplementary.
By definition of supplementary
⇒
.....[1]
From the figure, you can see that:
and
are also supplementary.
⇒
.....[2]
By [1] and [2] we have;
⇒
Simplify:

Since ∠2 and ∠3 are corresponding angles.
Corresponding angles states when the two lines are parallel, then Corresponding Angles are equal and vice versa.
by definition we have;
proved!
Answer:
Mid point of the given end points = 
Step-by-step explanation:
Given the end points of the line segment are :
(0,
) & (
,0)
We will use the mid point formula when two points are: (x₁,y₁) & (x₂,y₂)
mid point = 
now put the value of x₁ = 0
x₂ = 
y₁ = 
y₂ = 0
mid point = 
= 
That's the final answer.
Answer:
<h2>x=(y-105)/7</h2>
Step-by-step explanation:
Given that the total time taken to practice is given by the expression as
y=7(15+x)
Simplifying the expression we have
y=105+7x
Solving for x (that is making x subject of formula we have)
7x=y-105
Divide both sides by 7 we have
x=(y-105)/7
Therefore the expression is
x=(y-105)/7
