Question

50 дм²+50м²=? 7м²+70дм²=?8а-80м²=?60а+30м²=?10см²+1000см=?500м²+6а=?

Answer 1

Ответ:

50 дм^2 + 50 м^2 = ( 0, 5 + 50 ) м^2 = 50, 5 м^2

7м²+70дм²= 7,7 м^2

8а-80м² = 8*10 м^2 - 80 м^2 = 0

a = 10 м^2

60a + 30 м^2 =0, т.к. a = -1/2

a = -500/6

500m^2 - 500 m^2 = 0

Answer 2

To perform the calculations, we need to convert all the measurements to the same units (either square decimeters or square meters) before adding them together.

1. 50 дм² + 50 м²: Since we want to add areas, we need to convert all measurements to square decimeters (1 м² = 100 дм²). 50 м² = 50 * 100 дм² = 5000 дм² 50 дм² + 5000 дм² = 5050 дм²

2. 7 м² + 70 дм²: Convert 7 м² to дм²: 7 * 100 = 700 дм² 700 дм² + 70 дм² = 770 дм²

3. 8а - 80 м²: There seems to be a missing value for 'a'. We can't perform the calculation without knowing the value of 'a'.

4. 60а + 30 м²: Again, we need to know the value of 'a' to perform the calculation.

5. 10 см² + 1000 см: We have measurements in both square centimeters and centimeters, but they are different types of measurements and can't be directly added.

6. 500 м² + 6а: Without knowing the value of 'a', we can't perform the calculation.

Please provide the missing values for 'a' and the correct units for the fifth calculation, and I'll be happy to assist further.
