The coefficients in the expression are 3 and 7.
An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
Now the given expression is,
9 - 4 + 3b + 7a
So, from the given expression we can see that there are 4 terms, 2 constants and 2 coefficients.
The coefficient of b is 3,
and coefficient of a is 7.
So, there are 2 coefficients in the given expression.
Thus, the coefficients in the expression are 3 and 7.

By understanding the rate at which each oven bakes the bread, we can calculate that it would take the small oven 12 hours to bake the bread for one day.
To solve this problem, we need to first understand the rate at which each oven bakes the bread. When both ovens are working together, it takes 3 hours to bake a day's worth of bread. This means their combined rate of work is 1/3 of the day's bread per hour. However, when only the large oven is used, it takes 4 hours to complete the same amount of work. Therefore, the large oven's rate of work is 1/4 of the day's bread per hour.
Our goal is to find the small oven's rate of work. To do this, we subtract the large oven's rate of work from the combined rate of work. This leaves us with 1/3 - 1/4 = 1/12 of the day's bread per hour. Therefore, it would take the small oven 12 hours to bake the bread for one day on its own.
