The price of nails, n, is $1.29/lb, the price of washers, w, is $0.79/lb, and the price of bolts, b, is $2.39/lb. write an expression to represent the total price of the supplies.

The expression to represent the total price of the supplies is 1.29n + 0.79w + 2.39b

Solution:

Let "n" be the number of nails

Let "w" be the number of washers

Let "b" be the number of bolts

Given that ,

Price of nail = $ 1.29 per lb

Price of washers = $ 0.79 per lb

Price of bolts = $ 2.39 per lb

To find: Expression to represent the total price of the supplies.

Total price = number of nails x Price of nail per lb + number of washers x Price of washers per lb + number of bolts x Price of bolts per lb

Thus the expression to represent the total price of the supplies is found

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3

solve systems of equations by graphing. a system of linear equations contains two or more equations e.g. y=0.5x+2 and y=x-2. the solution of such a system is the ordered pair that is a solution to both equations. to solve a system of linear equations graphically we graph both equations in the same coordinate system
