Answer:
17
Step-by-step explanation:
54 has 4 ones
and 5 tens
37 has 7 ones
and 3 tens
subtracting ones
7 ones are taken from 54
so along with the existing 4, 1 ten is decreased and another 3 ones are decreased resulting in 7 ones now
now 54 has 5-1= 4 tens
subtracting tens we get 4-3=1
Therefore 1 ten and 7 ones
⇒ 17

Answer:
Yes, the center of a circle is always and always equidistant from all the points on circumference because that is because what a circle is called. The distance from the center of the circle to the circumference is called the radius and it is constant for any particular circle.
Answer:
<h2><u>
y = -2x</u></h2>
Step-by-step explanation:
If you notice very carefully then you will see that the line passes through the points :
( 1 , - 2 )
( - 1 , 2 )
Hence the value of x = 1 when the value of y = - 2 .
We know that - 2 × 1 = - 2
⇒ - 2 x = y
⇒ y = - 2x
Hence the first OPTION is correct .
Verification :
For points ( - 1 , 2 ) we can write :
y = - 2x
⇒ 2 = - 2 × - 1
⇒ 2 = 2
Hence the answer is verified .
Always try to use the converse of the graphical method .
( Nothing converse is there ... just saying the opposite steps of that method :P )
I mean in graphical method we plot points and then join , here identify the joined points and then make the equation .
The length of the shorter side is 7 longer side is 12 7+7+12+12 is 38 and 7x12 is 84
