Answer 1

В

(89+51):7,9-53,7=-35,97

1)89+51=140

2)140:7,9=17,73

3)17,73-53,7=-35,97

Р

(180:18+620):7,5=84

1)180:18=10

2)620+10=630

3)630:7,5=84

А

96,10:6+80-50=46,02

1)96,10:6=16,02

2)16,02+80=96,02

3)96,02-50=46,02

Answer 2

It looks like you've provided a series of mathematical expressions. Let's break down and solve each one step by step:

1. B (89+51): This is equivalent to B * (89 + 51) = B * 140.

2. 7.9 - 53: This is a simple subtraction, which equals -45.1.

3. 7P (180:18 + 620): First, solve the inner expression inside the parentheses: 180 divided by 18 is 10, and then add 620, which equals 630. So, 7P(10 + 630) = 7P * 640.

4. 7.5A96. 10:6: This appears to be written with spaces in between. Assuming the spaces are meant to be mathematical operations, it could be interpreted as 7.5 * A96 * 10 / 6.

5. 80 - 50д(88:22 + 60:5): First, solve the inner expression inside the parentheses: 88 divided by 22 is 4, and 60 divided by 5 is 12. So, 80 - 50 * 16 = 80 - 800 = -720.

6. 8H (560:7.8 + 80): First, solve the inner expression inside the parentheses: 560 divided by 7.8 is approximately 71.79, and then add 80, which equals approximately 151.79. So, 8H * 151.79.

7. 99И200 - 210:(58+12): First, solve the inner expression inside the parentheses: 58 + 12 = 70. Now, 99И200 - 210 * 70.

8. 50Й (210:6 + 7): First, solve the inner expression inside the parentheses: 210 divided by 6 is 35, and then add 7, which equals 42. So, 50Й * 42.

9. (28:4): This is a simple division operation, which equals 7.

Now, you have a series of expressions in terms of variables (B, P, A, H, and И) that need their values to be substituted to get numerical results. Without the values of these variables, we can't compute the final numeric answers. If you provide the values for these variables, I can help you calculate the final results.
