Question

45х+55х,если х=303,х=48

Answer 1

Сначала упростим выражение
45х+55х=100х
Если х=303, то 100х=100*303=30300
Если х=48, то 100х=4800
Ответ: 30300;4800

Answer 2

45х+55х=100х
100х=100×303=30300
100х=100×48=4800

Answer 3

To calculate the value of the expression 45x + 55x for two different values of x, let's substitute the given values and solve:

For x = 303: 45(303) + 55(303) = 13635 + 16665 = 30300

For x = 48: 45(48) + 55(48) = 2160 + 2640 = 4800

Therefore, if x is 303, the value of the expression is 30,300, and if x is 48, the value of the expression is 4,800.
