Question

259x+12-159x, x=483 466a+23a+730a, a=140

Answer 1

Ответ:

1) 48312

2)170660

Пошаговое объяснение:

1) 259x + 12 -159x = 100x + 12

2) так как x = 483, то 100x + 12= 100*483 +12 = 48312

3) 466а + 23а + 730а = 489а + 730а = 1219а

4) 1219* 140 = 170660

Answer 2

To evaluate the expressions, let's substitute the given values for the variables and simplify the expressions:

1. For the expression 259x + 12 - 159x, where x = 483: Substitute x = 483: 259(483) + 12 - 159(483) = 125,697 + 12 - 76,437 = 49,272

   Therefore, when x = 483, the expression 259x + 12 - 159x equals 49,272.

2. For the expression 466a + 23a + 730a, where a = 140: Substitute a = 140: 466(140) + 23(140) + 730(140) = 65,240 + 3,220 + 102,200 = 170,660

   Therefore, when a = 140, the expression 466a + 23a + 730a equals 170,660.
