For this case we have the following system of equations:

From the first equation we clear "x":

We substitute in the second equation:

We apply distributive property:

We add similar terms:

We add 65 to both sides:

We divide between 22 on both sides:

We look for the value of the variable "x":

Thus, the solution of the system is:

Answer:
25%
Step-by-step explanation:
Start by dividing 84 by 4 and you get 21. Then take 100 and divide that number by 4, and you get 25. There is your answer. The 21 jars of grape jelly are equal to 25% of the number 84. Hope this helps!
It would be 24 units^2 because the middle is 16 and the two triangles are 4 each
Sin (A) = BC/AB = 21/75= 7/25
PEMDAS
you would do left to right and look for multiplication or division.
64/2= 31
31*16=512
