Mathematics
1 answer:
bekas [8.4K]3 years ago
8 0

Answer:

Step-by-step explanation:

Let the length b y

Width = 2x - 3

Perimeter = 18x + 4

And

Perimeter = 2(l + w)

18x + 4 = 2(y + 2x - 3)

Dividing through by 2

9x + 2 = y + 2x - 3

Making y as subject

y = 9x - 2x + 2 + 3

y = 7x + 5

The missing side is 7x + 5

If the sum of four consecutive numbers is 854, what is the third one?
lukranit [14]

Answer:

214

Step-by-step explanation:

The set up would be x + (x + 1) + (x + 2) + (x + 3) = 854, naturally as the numbers are consecutive. Solving for x:

x + (x + 1) + (x + 2) + (x + 3) = 854,

x + x + 1 + x + 2 + x + 3 = 854,

4x + 1 + 2 + 3 = 854,

4x + 6 = 854,

4x = 854 - 6 = 848,

x = 848/4 = 212

The third number then should be 212 + 2 = 214

How are the solutions to the inequality -3x>18 different from the solutions to -3x>18 ?
Novay_Z [31]

Answer:

x < -6

Step-by-step explanation:

 -3x > 18

Divide both sides by -3

-3x/-3 < 18/-3

Note : in inequalities when both sides are divided by negative or minus, the inequality sign changes.

Therefore

x < -6

There's no difference as the equations are the same
