Answer:
THE VALUE OF x = 20 ;
Step-by-step explanation:
Since the quadrilateral PQRS is parallelogram,
Opposite sides are congruent , i.e QR =PS & PQ = RS
NOW EQUATING THE SIDES,
⇒ 4x - 15 = 3x +5
⇒ x = 20
Answer:
A
Step-by-step explanation:
3.99-1 = 2.99 they lose 2.99 per burger
Multiply the number of people by the amount lost per burger:
2.99 x 86,047 = 257,280.53
They would lose: $257,280.53
x = 13
subtract x from both sides of the equation
6 = 2x - x - 7
6 = x - 7
add 7 to both sides
6 + 7 = x ⇒ x = 13
As a check
substitute this value into the equation and if both sides are equal then it is the solution
left side = 13 + 6 = 19
right side = (2 × 13) - 7 = 26 - 7 = 19
hence x = 13 is the solution
