Each week, abigail earns $75 for every shift she works at the pizzeria and $25 for every dog-walking job. she uses the expression 75x + 25y to keep track of her earnings. part a: identify the coefficients and variables in the expression. (3 points) part b: how many terms are in the expression, what are they, and how do you know? (4 points) part c: which term in the expression shows the total earned from the pizzeria? (3 points)

Here, the given expression that shows her total earning ( in dollars ),

75x + 25y,

Part A :

Variable is the quantity that can be vary in an expression,

Typically, It can be represented by a single letter,

Coefficients is numeric quantity that is placed before the variable,

So, in the above expression,

x and y are variables,

75 and 25 are coefficients,

Part B :

Terms are the single number or variable or a variable with a coefficient which are separated by mathematical signs ( +, - or etc ),

So, in the above expression,

75x and 25y are terms,

So, the expression has 2 terms,

Part C :

In the expression 75x + 25y

75 shows her earning for every shift she works at the pizzeria,

25 represents her earning for every dog-walking job,

Since, total earning = earning for each unit × number of unit,

Thus, the variable having coefficient 75 must shows the number of shifts,

Hence, 75x would be show the total earned from the pizzeria.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
