Answer:
7
Step-by-step explanation:
Given that there are 5 number cards.
They are 2,5,7,8,9
Total of all numbers in the cards = 2+5+7+8+9= 31
One card is removed say with number x.
Now sum new would be =31-x .. i
Average of remaining 4 cards = 6
So sum of remaining 4 cards = 6(4) = 24 ... ii
i and ii represent the sum of remaining 4 cards. Hence they should be equal
31-x =24
Subtract 31 from both sides to get
-x=-7
Or x =7
You can multiply 6p + m = 9 by -2 so you gonna have -12p - 2m = -18 then you can say : -12p - 2m = -18 ⇒ -8p = -10 ⇒ p = 10/8 ⇒ p = 1.25
4p + 2m = 8
so now you can find the m : 6 * 1.25 + m = 9 ⇒ 7.5 + m = 9 ⇒ m = 9 - 7.5 ⇒ m= 1.5 :)))
i hope this is helpful
have a nice day

4 is the base.
Answer:
-3x + 6
Step-by-step explanation:
Distribute the 3 across the parentheses, like you are multiplying. 3 x (-x) = -3x and 3 x 2 = 6. Then write as an expression.
Transformation involves moving a shape away from its original position
- The transformation to move the cabinet to a new position is translation
- The transformation to place the chair directly across the couch is reflection
<em>The required diagrams to answer this question are missing; so, I will provide a general exam</em>
<em />
<u>(a) Moving the cabinets</u>
The question says that the cabinets are moved away from their original position.
Since terms like <em>"rotation" or "reflection"</em> are not used, then the general transformation used for "moving" is translation.
Hence, the transformation is translation
<u>(b) Changing the position of the chairs</u>
The question says that the chairs would be placed directly across the couch.
The term "directly across" is used for reflection of a shape.
Hence, the transformation is reflection
