Answer:
the simplified expression is: 6y-7x
Step-by-step explanation:
-y+7y= 6y
-7x
= 6y-7x
Answer:
k = 324
Step-by-step explanation:
Y varies inversely as x
Let k be the constant of variation
Y = k/ x
Y= 36 and x= 9
Substitute the value of Y and x
36 = k/9
Make k the subject of the formula
k= 36*9
k =324
Answer:
x=6
Step-by-step explanation:
In a square, its angles are all 90 degrees. So, cutting a square in half into two triangles from corner to corner produces 45 degree angles on both sides. Since the triangles are now 45-45-90 triangles, we can use the rule where the hypotenuse of the triangle is equal to the square root of 2 times the length of either side. So, the side length is 6.
The answer would be 54, because A= PQ over 2 = 9 x 12 over 2 = 54
The total cost for a $1,200 washing machine is $1,200. In the real world it would be 1,200 + tax.
