xavier has $23.50 in his savings account. he deposits $35 every week. his mother also deposits $20 into the account every time xavier washes the car. his savings account balance can be shown with the following expression: 20c + 35w + 23.50 part a: identify a coefficient, a variable, and a constant in this expression. (3 points) part b: if xavier saves for 12 weeks and washes the car 3 times, how much will he have in his account? show your work to receive full credit. (4 points) part c: if xavier’s mother deposited $25 after each car wash, would the coefficient, variable, or constant in the expression change? why? (3 points) (10 points)

Part A: a coefficient is either 20 or 35, both work. A variable is c or w, again either work.  The constant is 23.50.

Part B: He will have $503.50

Part C: The coefficient would change, because the amount per car changes, not the amount of cars.

Step-by-step explanation:

A coefficient goes in front of the variable (which is the letter, usually shown as x). The constant is a number with no variable attached.

We replace c with 20, and w with 12, giving us 20(3)+35(12)+23.50 for our equation. After multiplying, we come up with 60+420+23.50, which equals 503.50.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.
