Answer:

x = [tex]21^{o}[/tex]

Step-by-step explanation:

The opposite sides of the parallelograms are equal and parallel to each other. Thus, from the alternate angle principle (alternate angles are said to be equal), then;

2x = 42  (alternate angle principle)

x = [tex]\frac{42}{2}[/tex]

 = [tex]21^{o}[/tex]

x = [tex]21^{o}[/tex]

Therefore the value of x in the question is [tex]21^{o}[/tex].

Answer:

30 minutes

Step-by-step explanation:

First you can break down the percent and the time into a fraction

You can divide it by 2

so 2%/1   (2% in 1 minute)

Then you find the amount of time it would take to paint the whole bookcase

2 * 100 = 50

So time to paint the whole bookcase would be 50

50 - 20 = 30

Answer:

30 minutes

Step-by-step explanation:

He paints 40% of the bookcase in 20 minutes.

The rest of the bookcase is 100% - 40% = 60%.

60% of the bookcase still needs painting.

40% is to 20 minutes as 60% is to x minutes

40/20 = 60/x

Reduce the fraction on the left side.

2 = 60/x

Multiply both sides by x.

2x = 60

Divide both sides by 2.

x = 30

Answer:

36

Step-by-step explanation:

3/4y=6-1/3c

3/4y+1/3c=6

multiplied 6 into equation to get 2c

9/2y+2c=36

so 2c+9/2y=36

The value of 2c + (9/2)y is 36.

Given,

(3/4)y = 6 - (1/3)c

We need to find the value of 2c + (9/2)y.

It depends on the type of expression.

We need to see what is required to find in the expression.

If we need to find 2x in an equation of x + 7 = 3 + y

x + 7 = 3 + y

We will multiply 2 in the equation.

2( x + 7 ) = 2 ( 3 + y )

2x + 14 = 6 + 2y

2x = 6 + 2y - 14 is our answer.

Find 2c + (9/2)y

We have,

(3/4)y = 6 - (1/3)c

We need to write it as:

(3/4)y + (1/3)c = 6 _______(1)

We need to make (1/3)c into 2c and (3/4)y into (9/2)y.

Multiply 6 on both sides on (1).

6 x [ (3/4)y + (1/3)c ] = 6 x 6

6 x (3/4)y + 6 x (1/3)c = 36

[ (3 x 3) / 2] y + (6/3) c = 36

(9/2)y + 2c = 36

2c + (9/2)y = 36

Thus the value of 2c + (9/2)y is 36.

Step-by-step explanation:

The function f(x) = {x + 3,  x < 0,    3      x ≥ 0} represents the graph.

In mathematics, the set of ordered pairings where f(x)=y exists is the graph of a function f. These pairs are Cartesian coordinates of points in two-dimensional space and so form a subset of this plane in the typical situation when x and f(x) are real integers.

here, we have,

given that,

As show in the graph we can see that the function has a graph of x + 3 on left side of the y - axis for x < 0.

And the function has the constant graph y = 3 for x ≥ 0.

Therefore, the given graph is the graph of the function,

f(x) = {x + 3,  x < 0,    3      x ≥ 0}.
