The exterior angle is = to the 2 interior angles.
83 = (9x + 4) + (4x + 1) Remove the brackets
83 = 9x + 4 + 4x + 1 Group the like terms
83 = 9x + 4x + 4 + 1 Add the like terms.
83 = 13x + 5 Subtract 5 from both sides.
78 = 13x Divide by 13
78 / 13 = x
x = 6
So They want the angles
9x + 4 = 9*6 + 4 = 58
4x + 1 = 4*6 + 1 = 25
When you add these two together you should get 83. Do you?
Answer:
10 one-dollar and 4 five-dollar bills.
Step-by-step explanation:
Let x = the number of one-dollar bills and y = number of five-dollar bills.
Then:
x + y = 14
x + 5y = 30 (using the values of the bills)
Subtracting the 2 equations:-
-4y = -16
y = 4
so x + 4 = 14
x = 10.
There are 10 one-dollar bills and 4 five-dollar bills.
