Option A
The system of equations are x + y = 40 and 10x + 7y = 360
<em><u>Solution:</u></em>
Let pounds of expensive coffee beans be x
Let pounds of cheaper coffee bean be y
Cost of 1 pound of expensive coffee bean = $ 10
Cost of 1 pound of cheaper coffee bean = $ 7
<em><u>The shop also sells a 40 pound mixture of the two kinds of coffee beans</u></em>
pounds of expensive coffee beans + pounds of cheaper coffee bean = 40
x + y = 40 ------ eqn 1
<em><u>The shop also sells a 40 pound mixture of the two kinds of coffee beans for $9 per pound</u></em>
pounds of expensive coffee beans x Cost of 1 pound of expensive coffee bean + pounds of cheaper coffee bean x Cost of 1 pound of cheaper coffee bean = 40 pound mixture x $ 9
10x + 7y = 360 --------- eqn 2
Thus the system of equations are x + y = 40 and 10x + 7y = 360
Thus option A is correct
The answer is 0 > 34, or No Solution to be exact. use the picture above as the appropriate symbol for No Solution.
Answer:
To determine the circumference, of the circle what you would need to do is to use the formula for the Circumference.
This formula can be seen as : C = Pi x Diameter.
C = 2 x Pi x R.
Answer:
<h3>
Commutative property</h3>
Step-by-step explanation:
The "Commutative Laws" say that when we add then we can swap numbers over and still get the same answer.
These are the angle measurements and the true measurements are written below the diagram,hope this helps you and question Pls ask me in the comments
