-19+3x-11+2x=2 What the answer

Mathematics
2 answers:
AveGali [126]3 years ago
5 0

Answer:

x = \frac{32}{5}

Step-by-step explanation:

Given

- 19 + 3x - 11 + 2x = 2 ← simplify left side

5x - 30 = 2 ( add 30 to both sides )

5x = 32 ( divide both sides by 5 )

x = \frac{32}{5} = 6.4

Answer:

x = 32/5

Step-by-step explanation:

First combine all the x terms:  -19+3x-11+2x=2  becomes -19 + 5x - 11 = 2

Next, combine the constants on the left side:  -30 + 5x = 2

Finally, add 30 to both sides:  5x = 32

Divide both sides by 5 to isolate x:  x = 32/5

Answer:

  • 45 regular keyboards
  • 15 wireless keyboards

Step-by-step explanation:

A set of 3 regular and 1 wireless keyboard would sell for ...

  3×$83 +110 = $359

For the given sales, the number of sets sold was ...

  $5385/($359/set) = 15 sets

Since there are 3 regular keyboards in each set, there were 3×15 = 45 regular keyboards sold. The number of each type of keyboards sold is ...

  45 regular keyboards and 15 wireless keyboards

<em>Comment on this solution</em>

When a problem statement tells you the ratio of one kind of item to another, it is often convenient to group the items in that ratio and deal with the groups. Sometimes, there will be a few missing or left over, for example "10 more than 3 times as many." In those cases, you can make an adjustment to the total and still deal with the groups. (Any equations you might write will effectively do this same thing.)

The length of each side is quadrupled. How many times larger is the new area when compared to the original?
GaryK [48]

16 times larger is the new area when compared to the original.

Given that, the length of each side of the square is quadrupled.

We need to find how many times larger is the new area when compared to the original.

<h3>What is the area of a square?</h3>

A square is a closed two-dimensional shape with four equal sides and four equal angles. The four sides of the square form the four angles at the vertices. The sum of the total length of the sides of a square is its perimeter, and the total space occupied by the shape is the area of the square. The formula to calculate the area of a square is a².

Let the length of each side of the square be x.

Then the length of each side of the new square will be 4x.

Now, the area of the original square = x²

The area of the new square = (4x)² = 16x²

So, the new square = 16 × the original square

Therefore, 16 times larger is the new area when compared to the original.
