Answer 1

1)13*25+244+24*25-67= 858
2)48*17-13*17+876=1471
3)75+36*421+27+64*421=42202
4)35*73+204+66*73-199=7378

Answer 2

13*25+244+24*25-67=325+244+600-67=1102

48*17-13*17+876=816-221+876=1471

19*23+457+39*23-278=437+457+897-278=1513

Answer 3

1) 13у + 244 + 24у - 67, если у = 25: To find the value of the expression, we substitute the value of у into the expression and simplify: 13 * 25 + 244 + 24 * 25 - 67 325 + 244 + 600 - 67 569 + 600 - 67 1169 - 67 The value of the expression is 1102.

2) 48т - 13т + 876, если т = 17: Similarly, we substitute the value of т into the expression and simplify: 48 * 17 - 13 * 17 + 876 816 - 221 + 876 The value of the expression is 1471.

3) 19х + 457 + 39х - 278, если х = 23: Substituting the value of х into the expression and simplifying: 19 * 23 + 457 + 39 * 23 - 278 437 + 457 + 897 - 278 The value of the expression is 1513.

4) 75 + 36т + 27 + 64т, если т = 421: Again, we substitute the value of т into the expression and simplify: 75 + 36 * 421 + 27 + 64 * 421 75 + 15156 + 27 + 26944 The value of the expression is 42102.

5) 35х + 204 + 66х - 199, если х = 73: Substituting the value of х into the expression and simplifying: 35 * 73 + 204 + 66 * 73 - 199 2555 + 204 + 4818 - 199 The value of the expression is 7378.

6) 26а + 421 + 74а - 241, если а = 39: Once again, we substitute the value of а into the expression and simplify: 26 * 39 + 421 + 74 * 39 - 241 1014 + 421 + 2886 - 241 The value of the expression is 4080.

So, the values of the given expressions are as follows: 1) 13у + 244 + 24у - 67, если у = 25: 1102 2) 48т - 13т + 876, если т = 17: 1471 3) 19х + 457 + 39х - 278, если х = 23: 1513 4) 75 + 36т + 27 + 64т, если т = 421: 42102 5) 35х + 204 + 66х - 199, если х = 73: 7378 6) 26а + 421 + 74а - 241, если а = 39: 4080
