A) Let b and r represent the cost of a bag of bark mulch and red mulch, respectively. (Always start with a "let" statement that defines your variables--usually based on what the question is asking: cost of each type.)
8b +6r = 44.50 . . . . Paul's first purchase
1b +8r = 25.50 . . . . .Paul's second purchase
b) There are many ways to solve a set of linear equations like this. I like a graphical calculator because it gives me the solution without having to think too much or do any arithmetic.
(b, r) = (3.50, 2.75)
Pine bark mulch costs $3.50 per bag.
Red mulch costs $2.75 per bag.
c) The project cost would have been
.. 14*$3.50 +10*$2.75 = $76.50
Paul would NOT have been able to make that purchase with funds available.
Car 1 consumes 30 gallons of gas.Car 2 consumes 20 gallons of gas.

Answer:
800 grams
Step-by-step explanation:
While converting kg into grams we multiply by 1000
hence
0.8*1000 grams
800 grams
Answer:
10/18
Step-by-step explanation:
To convert 1.8 to a reciprocal, you first need to change it into a fraction.
1.8 basically expresses 1
which equals
.
Since a reciprocal is just switching the top and bottom of a fraction, your reciprocal of 1.8 will be
.
You can simplify this if you want, to get
. Either one is correct.
