Question

80-2a, для а =27 3x-9y, для x =208, y =52

Answer 1

80-2*27=26
3*208-9*52=566

Answer 2

To evaluate the given expressions, simply substitute the given values into the expressions and perform the necessary calculations:

1. For the expression 80 - 2a, where a = 27: 80 - 2 * 27 = 80 - 54 = 26

2. For the expression 3x - 9y, where x = 208 and y = 52: 3 * 208 - 9 * 52 = 624 - 468 = 156

So, the values of the expressions are:

1. 80 - 2a = 26
2. 3x - 9y = 156
