Step-by-step explanation:
Find the slope of JK by the formula :y2-y1/(x2-x1) whose value is 4/5
similarly, calculate the slope of GH it's value is also 4/5
Find slope of GK now by same formula y2-y1/( x2-x1 ).the value will be -5/3
Similarly calculate slope of HJ and you will get its value to be -5/3
since parallel lines have equal slopes JK and GH are parallel and GK and HJ are parallel. Since opposite sides are parallel GHJk is parallelogram
Answer:
AC=BC its looks like isosceles triangle
Step-by-step explanation:
Answer: Number of children = 168
Number of adults = 120
Step-by-step explanation:
Let x = Number of children and y = Number of adults
As per given,
x+y=288 (i)
2.25x+6.80y =1194 (ii)
Multiply 2.25 on both sides in (i)
2.25x+2.25y= 648 (iii)
Eliminate (iii) from (ii)
4.55y=546
Put y= 120 in (i)
x+120=288
⇒ x=288-120
⇒ x= 168
Hence, Number of children = 168
Number of adults = 120

Answer: 1.3</h3>
========================================
Work Shown:
The two points we have are and
Apply the distance formula
-------------------------
A shortcut is possible by subtracting the y coordinates of the two points, and making the result positive through the use of absolute value.
So we either say
|y1-y2| = |1.2-2.5| = |-1.3| = 1.3
or,
|y2 - y1| = |2.5 - 1.2| = |1.3| = 1.3
We get the same result. This shortcut is valid because the x coordinates of both points are the same.
Answer:
y < 5
Step-by-step explanation:
Given
y + 1 < 6 ( isolate y on the left side by subtracting 1 from both sides )
y < 5
