In this case, we must analyze the question to find the solution.

Step 01:

equation one variable vs system of equations two variables = ?

Step 02:

In an equation with one variable, we must only apply the algebraic rules to find its value.

For systems of equations, we have different methods to solve them.

And it is possible to write the equations as a function of one variable, and then substitute in the other equation and thus find the solution.

Therefore, it is comparable to solving one variable equation.

That is the answer.

Two angles are supplementary to each other. If the first angle measures 58 then which of the following could be the measure of t

34kurt

Answer: 122°

Step-by-step explanation:

When an angle is supplementary to each other , it means the angle measures to 180°.

Now since one of the two angles is 58°, therefore, the other angle will be

180° - 58°

= 122°

Mrs. Ishimitsu is installing a rubber bumper around the edge of her coffee table. The dimensions of the rectangular table are (2

ollegr [7]

Answer:

$2x^2+8x-30$ represents the total perimeter of the table, and if x = 3 the lentgh of entire rubber bumper is 12 feet.

Step-by-step explanation:

Perimeter is defined as the sum of sides.

For a rectangle having dimension length 'L' and breadth 'B' Since, rectangle has two sides equal.

Perimeter of rectangle = 2 ( length + breadth )

Here, given rectangle has dimension

Length = $2x^2-16$ and breadth = $-x^2+4x+1$

Thus, perimeter of rectangle = $2(2x^2-16+(-x^2+4x+1))$

$=2(2x^2-16-x^2+4x+1)$

$=2(x^2+4x-15)$

$=2x^2+8x-30$

Thus, perimeter of rectangle is $2x^2+8x-30$ ........(1)

Perimeter of rectangle , when x = 3,

Put x= 3 in (1) ,

$2x^2+8x-30\Rightarrow 2(3)^2+8(3)-30 \Rightarrow 18+24-30=12$

Thus, $2x^2+8x-30$ represents the total perimeter of the table, and if x = 3 the lentgh of entire rubber bumper is 12 feet.

20 km is how many dam

ZanzabumX [31]

Hello!

OK, so we need to find out 20 km = ? dam

What we know:
1 km = 100 dam

Now, lets multiply to get our answer:

20 × 100 = 2,000

This tells us that 20 km = 2,000 dam

Check:

2,000 ÷ 20 = 10

This tells us that we are CORRECT!

Answer: 20 km = 2,000 dam

Hope this helps! Good luck! (:
