Answer: The cost of one sandwich is $4.25 and the cost of one cup of coffee is $2.25.
Step-by-step explanation:
Let x be the cost of one sandwich and y be the cost of one cup of coffee.
By considering the given situation, we have the following equations :-
Multiply 2 on both sides of equation (2) , we get
Subtract equation (1) from equation (3), we get
Put value of y in (1), we get
Hence, the cost of one sandwich is $4.25 and the cost of one cup of coffee is $2.25.

Answer:
Step-by-step explanation:
A) x/840=1/21
x=(1/21)*840=840/21=40
x=40
------------------
B) 14/x=16/20
simplify 16/20 into 4/5
14/x=4/5
x=14/(4/5)=(14/1)(5/4)=70/4
simplify
x=35/2

1. pour calculer la distance OF on va utiliser tout simplement le théorème de pythagore
OF = √(68²+51²)
OF = √(4624+2601)
OF = √(7225)
OF = 85 mm
2. étant donné que la cible n'est pas atteinte si la pointe de la flèche est sur le bord, et on sait que le rayon de la cible est 100
donc la distance OF ne doit pas dépasser le nombre 100
OF < 100

Answer:
24.75
Step-by-step explanation:
2x-11 + 6x-7 =180
8x-18=180
8x=198 /8
x=24.75
