x = -3 , y = 6 , z = -4
Take Given equation :
⇒-15 + (-x) + y = 0
substitute values of x and y
⇒-15 + [- ( -3)] + 6
⇒-15 + (3) + 6
⇒-15 + 9
⇒-6
Hence, value of -15 + (-x) + y = - 6
Answer:
x is 5
Step-by-step explanation:
45/36 was divided by 9 to get 5/4
You would divide 5320 by 61 to get 87.2131
Answer:
Step-by-step explanation:
Let x be the amount of flour and y be the amount of sugar ordered.
Since, the order of flour and sugar weighs 15 pounds.
Therefore,
Also, Flour costs $0.80 per pound and sugar costs $0.50 per pound.
The cost of ordered flour=$0.80x
The cost of ordered sugar=$0.50y
Now, the total cost of the order=
Hence, for the given situation the system of equations is:-
