The first thing we are going to do for this case is to define the following variable:
 x = number of trees.
 We then have that the equation that represents the problem is given by:
 y = 50 (x-1) + 20
 Rewriting:
 y = 50x - 50 + 20
 y = 50x - 30
 Substituting for y = 390 we have:
 390 = 50x - 30
 We clear x:
 x = (390 + 30) / (50)
 x = 8.4
 nearest whole integer
 x = 8
 Answer:
 
will be planted along one block about 8 trees.

Answer:

Number of trees in both sides = 16

Step-by-step explanation:

The first tree will be at 20 feet from there trees will be 50 feet apart.

These are in arithmetic progression

           20, 70, 120 .............................

Last tree will at 370 feet.

We have

             a + ( n- 1 ) d = 370

              a = 20 and d = 50

               20 + ( n- 1 )  x 50 = 370

              ( n- 1 ) x 50 = 350

               ( n- 1 ) = 7

                 n = 8 trees

Number of trees in one side = 8

Number of trees in both sides = 16

What is the factorization of 121b^4 − 49?
lora16 [44]

Answer:

(11b^2 + 7) (11b^2 - 7)

Explanation:

Since both terms are perfect squares, factor using the difference of squares formula,  a^2 - b^2 = (a + b) (a - b) where a = 121b^4 and b = 49

Find the value of x in each of the following<br> a) x + 3 = 8<br> b) X-5 = 7
Georgia [21]

Answer:

a) x = 5

b) x = 12

Step-by-step explanation:

x + 3 = 8

Subtract 3 on both sides.

x = 8 - 3

x = 5

x - 5 = 7

Add 5 on both sides.

x = 7 + 5

x = 12

What is the geometric definition of a circle
Mazyrski [523]

Answer:

See explanation

Step-by-step explanation:

A circle is a figure where all of the points on its graph are equidistant from a single, central point. You can define a circle in a plane with the formula (x-h)^2+(y-k)^2=r^2, where h represents the x coordinate of the center, k represents the y coordinate, and r represents the radius. Hope this helps, and feel free to ask for more clarification!
