Kim has 120 cards in a box. She gave 6/10 of cards to Maddy. How many cards did Kim have left in the box?
1 answer:
In order to find out the answer to this question,, you must multiply 120 by 
120 x
Now that we have the expression,, we can start to solve. The first step to solve this problem is to reduce the numbers with 10
12 x 6
Then we multiply the numbers together to see how many cards Kim gave to Maddy.
72
Finally,, we need to subtract 72 from 120 to find out how many cards are left in the box.
120 - 72 = 45
This means that Kim has 45 cards left in the box.
Let me know if you have any further questions

Answer:
The value of y is 4
The equation of line is y = x + 7 .
Step-by-step explanation:
Given as :
The points are
(,
) = (- 3, y)
(,
) = (- 9, -2)
The slope = m = 1
Now,<u> The slope is calculated in points form</u>
So, Slope =
I.e m =
or, 1 =
or, 1 =
or, 1 × (-6) = - 2 - y
or, - 6 = - 2- y
or, y = - 2 + 6
∴ y = 4
So, The new points as
(,
) = (- 3, 4 )
(,
) = (- 9, -2)
<u>So, the equation of line in slope - point form can be written as</u>
y - = m ( x -
)
i.e y - 4 = ( 1 ) × ( x - (-3) )
or, y - 4 = x + 3
∴ y = x + 3 + 4
Or, y = x + 7
So, The equation of line is y = x + 7
Hence The value of y is 4
And The equation of line is y = x + 7 . Answer
