One number (a) exceeds another number (b) by 11 so
a = b+11
a + b = 77
Substitute the equation for a into the second equation
(b+11) + b = 77
multiply each side by 1 to remove parentheses
b + 11 + b = 77
Combine like terms
2b + 11 = 77
Isolate the variable
2b = 77-11
Simplify
2b = 66
Divide by 2
b = 33
Now substitute b back into the initial equation for a
a = (33) + 11
a = 44
Check your work by substituting both values into the second equation
44 + 33 = 77
This is true, so 44 and 33 are solutions
Hello there!
Pentagon = 5 sides.
For regular pentagon: 360/5 = 72. 180 - 72 = 108 degrees at each interior.
I hope this helps.

Answer:
6 crayons more
Step-by-step explanation:
At Dante's party, each child gets 192/16 = 12 crayons each
At Maria's party, each child gets 234/13 = 18 crayons each.
Therefore, each child at Maria's party gets 18-12 = 6 crayons more each than at Dante's party.
Answer:
Since its distance do the distance formula which is d= square root of x2-x1 squared plus y2-y1 squared. Plug in the numbers. in the square root house, it will be (3-(-4)) squared plus (7-6). Since its two negatives....it will be (3+4) squared plus 1 since 7-6=1. Then it will be the square root of 7 squared plus 1. it soon will be the square root of 50. You need to break the 50 apart to a perfect square. So find a perfect number....which have 2 multiples beside itself and 1. So 25 times 2 will be it since 25 is a perfect square. 50 squared equals the square root of 25 times 2. Now break the 25. it will be 5 times the radical of 2.
