The first option is correct because the expression [tex]5t+4y[/tex] has a coefficient of 5.
Important information:
- We need to find the expression that has a coefficient of 5.
Coefficient:
In the product of a variable and a constant, the constant number is called the coefficient.
For example, 4 is the coefficient of x in 4x.
The coefficients of [tex]5t+4y[/tex] are 5 and 4.
The coefficients of [tex]2x+3y[/tex] are 2 and 3.
The expression 0 has no coefficient.
The coefficient of [tex]3x+2[/tex] is 3.
Therefore, the first option is correct.
