Answer:
<h3>The missing value in the given solution is x=6</h3><h3>Therefore the solution is (6,-4)</h3>
Step-by-step explanation:
Given equation is 
<h3>To find the missing value in the solution to the equation :</h3>
- Let missing value in the solution be x
- Then the solution of the given equation is (x,-4)
Substitute the value of y=-4 in the given equation (1) we get
( adding the like terms )
Therefore x=6
<h3>Therefore the missing value in the given solution is x=6</h3><h3>Therefore the solution is (6,-4)</h3>
So since 2/5 of the washing machines have been sold that means 3/5 remain in the store
first find the number of washing machines that were in the store before any were sold
X is the number of washing machines in the store before selling
18=(3/5)X
18/(3/5)=X
X=18*(5/3)
X=30
so at the beginning there were 30 machines
then multiply the percent sold (2/5) by the number at beginning to find the number sold
(2/5)*30=12
so 12 machines were sold
to find the cost per machine divide the total price by number of machines sold so
$3840/12= $320
so the answer is $320 per machine
Answer:
Option B.
Step-by-step explanation:
It is given that,
Last year the total number of movies = 108
Number of action movies = 15
Based on this data, we need to find a reasonable estimate of the probability that the next movie is an action movie.
So, the required probability is:
Hence, the correct option is B.
Its False. addition and subtraction, Multiplication and division are inverse operations.
