Step-by-step explanation: I used a calculator ahaha.
If it only applies to 3a + 3ab + 7b – 2c – 4d then there is 5
If it applies to 5,9,7,1 and 3a + 3ab + 7b – 2c – 4d then there is 9
If 5,9,7,1 is a number then it is 6
New balance = -151.89 + 4.5x
(where x is the value of the smaller deposit)
The inicial balance was -126.89.
Then, it were made two deposits, one with the value of x, and one that is 3 1/2 times the other, that is, 3.5x.
Then, the customer made a withdraw of $25.
So, The new balance can be calculated as:
New balance = inicial balance + x + 3.5x - 25
New balance = -126.89 + 4.5x - 25
so far i think 9 but that's all I know for how
image them turning into triangles
