Answer:

x + 2

Step-by-step explanation:

Let x be the unknown number,

For making the diagram to model this problem,

Take a grid that shows x, ( shown below )

Then take a grid that shows 2.

Join these grids,

We obtain a grid, showing x + 2

Hence, the required expression that represents the given situation is x + 2

7x &lt; 10<br> please solve
Anvisha [2.4K]

Answer: The answer would be  x < 10/7

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

                    7*x (10)>0

Step by step solution :

STEP

1

:

Pulling out like terms

1.1     Pull out like factors :

  7x - 10  =   -1 • (7x + 10)

Equation at the end of step

1

:

STEP 2

:

2.1   Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

     7x+10  < 0

2.2    Divide both sides by  7  

     x+(10/7)  < 0

Solve Basic Inequality :

2.3      Subtract  10/7  from both sides

           x < 10/7

Inequality Plot :

2.4      Inequality plot for

        7.000 x  - 10.000  >  0

 

One solution was found :

x < 10/7

Find the perimeter of the shaded region. Round your answer to the nearest hundredth.
nataly862011 [7]

Answer:

59.16  units

Step-by-step explanation:

Given that,

The length of rectangle, L = 13

The breadth of the rectangle, B = 6

The perimeter of the shaded region = perimeter of rectangle - 2(perimeter of semicircle)

P=13\times 6-[2\times \dfrac{2\pi r}{2}]\\\\=78-2\pi r\\\\=78-2\times 3.14\times 3\\\\=59.16

So, the perimeter of the shaded region is 59.16  units.

Can i get some help on this question?
galben [10]

Answer:

a. 12.5

Step-by-step explanation:

Scale factor of ∆LMN to ∆XYZ = 2:5

To find length of side ZX, set the ratio of the corresponding sides of interest equal to the scale factor.

Thus:

ZX corresponds to NL = 5

NL:ZX = 2:5

5:ZX = 2:5

5/ZX = 2/5

Cross multiply

5*5 = ZX*2

25 = ZX*2

Divide both sides by 2

25/2 = ZX

12.5 = ZX

ZX = 12.5
