16/155 = n
explanation
A linear equation is an equation of a straight line. To solve linear equations, it is important to keep the following key concepts in mind:
Maintain balance of the equation by applying the same operations to both sides of an equation
Isolate for the variable by collecting like terms
Use inverse operations to rearrange an equation
to show your work
-8/ 5 = -31/2 • n
- 8/5 = -31n/2
2(-8/5) = 2 • -31/n
-16/5 = -31n
-16/5 / -31 = -31n/31
16/155 = n
Answer:
0 < x < 3
Step-by-step explanation:
3 < x + 3 < 6
Subtract 3 from all sides
3-3 < x + 3-3 < 6-3
0 < x < 3

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
Answer:
f+g is right answer.
Step-by-step explanation:
given
,
2x+3 is given and we have to find the combinations of h,f and g.
By trial and error we check h+f
= -4x-2
h-f = 10x-6
So these two are not correct
Try with h+g = 12x-3 and h-g = -6x-5
Hence these are also not right
Try with f+g
(f+g)(x) = f(x)+g(x) = -7x+2+9x+1 =2x+3
Hence f+g is right.
