Find x K (7x + 217 47 M

Mathematics
1 answer:
Butoxors [25]2 years ago
3 0

Answer:

x=16

Step-by-step explanation:

The opposite angles will always be supplementary

<K + < M = 180

47+ 7x+21 = 180

Combine like terms

7x+68 = 180

Subtract 68

7x = 180-68

7x = 112

Divide by 7

7x/7 = 116/7

x =16

seropon [69]

Answer:

If an inequality constraint holds as a strict inequality at the optimal point (that is, does not hold with equality), the constraint is said to be non-binding, as the point could be varied in the direction of the constraint, although it would not be optimal .There are two types of inequality constraints: limits on variables, often called explicit constraints such as Equation.The following table will make you even clear!

36cm = Side 1 + Side 2 + Side 3 + side 4

Because it's a square, all the sides are the same length, so we can rewrite this as:

36cm = 4*Side

Side = 36cm/4 = 9cm

So to find the area, we multiply a length side, by a width side.

In this case (a square), we have:
