Lets solve for both possibilities.
A. (2,4)
<span>-3x+5y=2x+3y
-3(2)+5(4)=2(2)+3(4)
-6+20=4+12
14</span>≠16
Incorrect
B. (3,3)
<span>-3x+5y=2x+3y
-3(3)+5(3)=2(3)+3(3)
-9+15=6+9
6</span>≠15
Incorrect
Neither ordered pairs work for the equation.
Answer=D
A because polygons have a closed pane
Answer: C=[ (10) x (19.60)÷ (8)]
Step-by-step explanation:
Given , The cost of 8 books = $ 19.60
Then, By UNITARY method , the cost of one book = ( Cost of 8 books ) ÷ ( 8)
i.e. The cost of one book = ($19.60) ÷ ( 8) ...(i)
Now , cost of 10 books = (10) x (Cost of one book)
From (i) , we get
Cost of 10 books =$[ (10) x (19.60)÷ (8)]
Let C be the cost of 10 books ( in dollars) .
So , the equation would help determine the cost of 10 :
C=[ (10) x (19.60)÷ (8)]
Answer:
18.18%
Step-by-step explanation:
55-45=10
10/55=0.18
Answer:
the expected rate of change in consumption is 11.83
Step-by-step explanation:
The computation of the expected rate of change in consumption is shown below:
= (Expected quadrillion thermal units - 2003 quadrillion thermal units) ÷ (difference in years)
= (563 - 421) ÷ (2015 - 2003)
= 142 ÷ 12
= 11.83
hence, the expected rate of change in consumption is 11.83
We simply applied the above formula so that the correct value could come
And, the same is to be considered
