Get x by itself
add 16 to both sides, so 4x = 16
divide both side by 4 and x =4
Collect the like terms
9x-5x=20
4x=20 divide both sided by 4
x=5
If 24 marks is 60 %, then full marks is 40
<em><u>Solution:</u></em>
Given that 24 marks is 60 %
We are asked to find the full marks
Let the full marks be "x"
So out of "x" marks, he has got 24 marks
Therefore,
60 % of full marks = 24
60 % of x = 24

Therefore, full marks is 40
<h3><u>Method 2:</u></h3>
If 60 % is 24, then we have to find what is 100 %
60 % = 24
100 % = x
This forms a proportion, So we can solve the sum by cross multiplying

Thus full marks is 40

Answer:
x = 19
A = 30°
B = C = 75°
Step-by-step explanation:
In an isosceles triangle, the angles opposite the congruent sides have the same measures.
A = B
3x +18 = 7x -58
76 = 4x . . . . . . . . add 58-4x
19 = x . . . . . . . . . divide by 4
Then the equal angles measure ...
A = B = 3(19) +18 = 75
C = 2(19) -8 = 30
Angles A, B, C measure 75°, 75°, 30°, respectively.
_____
<em>Alternate solution</em>
The sum of angles in a triangle is 180°, so you could write ...
(3x +18) +(7x -58) +(2x -8) = 180
12x = 228 . . . . . add 48
x = 19 . . . . . divide by 12
Answer:
Yes it is possible, given with 4 dots, lets say were set anywhere within a page or anywhere upon a circumference of a circle even. We can draw 4 straight lines to meet each corner and call this a quadrilateral.
Step-by-step explanation:
Squares, Rectangles and Rhombuses are all Parallelograms and squares and rectangles are regular quadrilaterals!
So any other 4 sided shape that is quadrilateral could be made.
The picture below shows all branches of quadrilaterals.
