The answer is:  " 100 " .
_______________________________________
Explanation:
_______________________________________

10x + 10(x+1) = 210 ;  Find "10x" ; 

10x + 10x + 10 = 210 ; 

20x + 10 = 210 ;

Subtract "10" from each side of the equation;
 
20x + 10 - 10 = 210 - 10 ;

20x = 200 ;

Divide EACH side of the equation by "20" ; to isolate "x" on one side of the equation; and to solve for "x" ;

20x / 20 = 200 / 20 ;

    x = 10
_____________________________
Solve for "10x";  the smaller multiple;

10x = 10 * x = 10 * 10 = 100 .
____________________________
The answer is:  " 100 " .

Guessing but 2x+10=210?  Then 2x=200, x=100.

The diameter of Circle Q terminates on the circumference of the circle at (0,3) and (0,-4). Write the equation of the circle in
Gnesinka [82]
First, determine the center of the circle by getting the midpoint of the points given for the circumference.
                    midpoint = ((0 + 0)/2, (3 + -4)/2)
                          midpoint (0, -0.5)
Then, we get the radius by determining the distance from either of the circumferential point to the center. 
                        radius = √(0 -  0)² + (3 +4)²  = 7
The equation for the circle would be,
                        x² + (y + 0.5)² = 7²

2.8, 3.4, 4.0, 4.6, . . . Write an equation for the nth term of the arithmetic sequence. Then find a50.
vova2212 [387]

Answer:

a_n = 2.2 + 0.6 n

a_50 = 32.2

Step-by-step explanation:

What's the common difference of this series?

a_1 = 2.8

a_2 = 3.4

Common difference = a_2 - a_1 = 3.4 - 2.8 = 0.6.

Expression for the nth term:

a_n = a_1 + (n - 1) \cdot\text{Common Difference} \\\phantom{a_n } = 2.8 + 0.6 \; (n-1) \\\phantom{a_n} = 2.8 + 0.6 \; n - 0.6\\\phantom{a_n} = 2.2 + 0.6\; n

n = 50 for the fiftieth term. Therefore

a_{50} = 2.2 + 0.6 \times 50 = 32.2.

A landscaper wants to create a 12-foot-long diagonal path through a rectangular garden. The width of the garden is x feet and th
nasty-shy [4]
If we let x be the width of the garden, then x+4 will be the length. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the legs.

         12² = (x)² + (x + 4)²

Simplifying,

    144 = x² + x² + 8x + 16

Further simplification,

    144 = 2x² + 8x + 16

           x² + 4x - 128 = 0

The value of x from the equation is 6.2 ft. The length is then equal to 10.2 ft.


The answer to this item is the second choice.
