Two basketball teams, the Tigers and the Bears, played several games. The Tigers won the first game by two points. The total num
aleksandrvk [35]

Answer: Tigers = 46     Bears = 44

<u>Step-by-step explanation:</u>

Let x represent the numbers of points scored by the Bears.

then x + 2 is the number of points scored by the Tigers.

Bears + Tigers = Total

  x      +  x + 2  =   90

            2x + 2 =   90

            2x       =    88

              x       =    44

Bears (x) = 44

Tigers (x + 2) = 44 + 2 = 46

questionten times a number, x, is one-half the sum of the number and three. which answer represents this situation? 10x
nataly862011 [7]

The solution of the equation 20x = x + 3 will be 3 / 19. Then the correct option is A.

<h3>What is Algebra?</h3>

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

Making anything easier to accomplish or comprehend, as well as making it less difficult, is the definition of simplification.

Ten times a number, x, is one-half the sum of the number and three. Then the equation will be

10x = 1/2(x + 3)

Simplify the equation, then we have

20x = x + 3

19x = 3

x = 3 / 19

The solution of the equation 20x = x + 3 will be 3 / 19. Then the correct option is A.

The missing options are given below.

A. 10x = 1/2(x + 3)

B. 10x = 1/2x

C. 10x = 1/2x + 3

D. 10x = (x + 3)
