1. Let the four consecutive numbers be x, x+1, x+2, x+3
The sum of four consecutive number is already given to us = 70
Therefore
⇒(x)+(x+1)+(x+2)+(x+3)=70
We need to combine x as we have four x terms in the equation. The next step is to get all of the x’s on one side of the equation and all the numbers on the other side. The same rule applies – whatever you do to one side of the equation, you must do to the other side as well!
⇒4x+6=70⇒4x=64⇒x=16
So, the four numbers are 16, 17, 18 and 19.
Hence, the greatest number among them is 19.
Have two ways: 1. Reflects with respect x-axis and later with respect y-axis.
2. The opposite: first with respect y-axis and later with respect x-axis.
B and D are correct.
Perimetr=4*side, so we know perimetr =64mm
so 4*side=64mm
side=64/4mm
side=16mm
Answer: side is 16 mm
The answer is The length of line segment AB is twice the length
of liar segment oC.
the length of line segment AB is twice the length of
line segment Bc.
Answer:
let length be b+5 and breadth be b
given,
perimeter of rectangle=150
or, 2(l+b) =150
or, 2(b+5+b)=150
or, 2b+5=150/2
or, 2b+5=75
or, 2b=70
therefore, b=35m
l=b+5
=35+5
=40m
