Question

(х-270)*30-478+(68+307)

Answer 1

(х - 270)×30 - 478 + (68 + 307) = 30х - 8100 - 478 + 375 = 30х - 8578 + 375 = 30х - 8203

Если это уравнение,то
30х - 8203 = 0
30х = 8203
х = 8203:30
х = 273×13\30 ( дробью записать)

Answer 2

(х-270)*30-478+(68+307)=30х-8100-478+375=30х-8203.

Answer 3

Let's simplify the expression using the order of operations (PEMDAS):

First, we'll simplify the expression inside the parentheses:

(68+307) = 375

Now we can substitute that value into the expression:

(х-270)*30-478+375

Next, we'll simplify the expression inside the first set of parentheses:

(х-270)

Finally, we'll simplify the entire expression:

(х-270)30-478+375 = 30х - 30270 - 478 + 375 = 30х - 8093

Therefore, the simplified expression is 30х - 8093.
