The first thing we must do for this case is to find the relationship between the variables.
We have then:
From here, we clear the value of "Y":
On the other hand we have:
From here, we clear the value of "x":
Then, replacing values we have:
On the other hand:
Finally, the perimeter is given by:
Substituting values we have:
Answer:
the perimeter of ABCD is:
44 units
Answer:
y = 200x + 7000
Step-by-step explanation:
950x-750x=200x
27,000-20,000=7000
hope this helps
Answer:
35/12
Step-by-step explanation:
1 1/2+1 5/12
=3/2+17/12
=3*6+17*1/12
=18+17/12
=35/12
In the given problem, we know that y is directly proportional to x.
We also know the direct variation formula.
y = kx
Now we need to substitute the value of x and y and find out the value of k. So
14 = 8k
Then
k = 8/14
= 4/7
Now in a new equation if we put the value of K and another value of x, then we can find the value of y.
y = (4/7) * 12
= 48/7
Let the new price of shoe before discount is “x”
75% of x = 60$
75/100x = $ 60
x = 60*100/75
x = $80
Therefore, the revised shoe price before discount should be $80, so that he can still get $60 even if he gives 25% discount.
