Ответ:

170

Пошаговое объяснение:

№1

9(а + х) - 3а + х = 9а + 9х - 3а + х = 6а + 10х

а = 15; х = 8

6а + 10х = 6 * 15 + 10 * 8 = 90 + 80 = 170

№2

60 * 3у * 20 = 3600у

у = 2

3600у = 3600 * 2 = 7200

Answer 3

To evaluate the expression 9(a + x) - 3a + x when a = 15 and x = 8, we substitute these values into the expression:

9(15 + 8) - 3(15) + 8

First, we simplify the expression inside the parentheses:

9(23) - 3(15) + 8

Next, we perform the multiplications:

207 - 45 + 8

Now, we perform the additions and subtractions:

160 + 8

Finally, we get the result:

168

Therefore, when a = 15 and x = 8, the expression 9(a + x) - 3a + x evaluates to 168.
