Answer:
18, the answer to 8+10 is 18, like you learn in 1st grade
$9 + $7 + $5 = $21 so $18 - $21 = account balance = -$3
Given:
Planes X and Y are perpendicular to each other
Points A, E, F, and G are points only in plane X
Points R and S are points in both planes X and Y
Lines EA and FG are parallel
The lines which could be perpendicular to RS are EA and FG.
Answer:
The value of x for the given expression is 5 .
Step-by-step explanation:
Given expression as
+
= 
Now, arrange the equation
So,
=
- 
<u>Taking L.C.M on right hand side </u>
Or,
=
Or,
=
Or, x = 
∴ x = 5
So, The value of x = 5
Hence,The value of x for the given expression is 5 . Answer
Answer:
The relationship between the circumference of a circle and its diameter represent a direct variation and the constant of proportionality is equal to the constant 
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form 
where K is the constant of proportionality
In this problem we know that
The circumference of a circle is equal to

therefore
the relationship between the circumference of a circle and its diameter is a direct variation and the constant of proportionality is equal to the constant
