Answer 1

Ответ:

у +30×5=450

у+30=450:5

у+30=90

у=90-30

у=60.

60+30×5=450

450=450

Ответ:у=60

с+4×25=985

с+4=985:25

с+4=39

с=39-4

с=35.

35+4×25=985

985=985

Ответ:с=35

Answer 2

It seems like you're trying to perform some mathematical calculations, but there appears to be a mistake in your equations. Let's correct them:

1. У+ 30 × 5 = 450 This equation is correct. У + 30 × 5 does indeed equal 450.

2. С+4×25 = 985 This equation is not correct. If you multiply 4 by 25, you get 100, so the correct equation would be: С + 100 = 985

Now, to find the value of С, you can subtract 100 from 985:

С = 985 - 100 = 885

So, the corrected equation is: С + 100 = 985, and С is equal to 885.
