Answer:
c = 1.5 d
Step-by-step explanation:
cost of 4 small drinks = $6
cost of 1 small drink = $ = $1.5
cost of d small drinks = 1.5 d = c
∴ c = 1.5 d
Answer:
d = 26/3
Step-by-step explanation:
Remove the parenthesis.

Answer:
x=-3
Step-by-step explanation:
2x+4=x+1
-x -x
x+4=1
-4 -4
x=-3
1) Parallelogram
2) Square
3) Rectangle
4) Trapezium or Trapezoid
Step-by-step explanation:
Step 1:
In a parallelogram the opposite sides will be parallel and equal
Square has all sides to be equal and the angles to be right angled.
In a rectangle, the four angles should be right angled and opposite sides should be equal.
A trapezoid or trapezium is a figure in which any of the pair of opposite sides should be parallel.
Step 2 :
1) This figure has opposite sides to be parallel and equal. Hence based on the first definition above, this is a parallelogram
Step 3 :
2) The second figure has opposite sides to be equal and the angles are of 90 degrees or right angled. Hence this is a square based on the second definition given in step 1
Step 4 :
3) The third figure has opposite sides to be equal and the angles are of 90 degrees or right angled. Hence this is a rectangle as per the 3 rd definition given in step 1
Step 5:
4 ) This figure has the horizontal pair of opposite sides to be parallel. Hence using the 4 Th definition in step 1, we can identify this as a trapezoid or trapezium.
