Question

45×2×y=900 , 45×2+b=900 , a-45×2=900

Answer 1

$45 \times 2 \times y = 900 \\ 90y = 900 \\ y = 10$


$45 \times 2 + b = 900 \\ 90 + b = 900 \\ b = 900 - 90 \\ b = 810$


$a - 45 \times 2 = 900 \\ a - 90 = 900 \\ a = 900 + 90 \\ a = 990$

Answer 2

Ответ:

45×2×y=900

y = 900/(45*2) = 900/90 = 10

45×2+b=900

b = 900 - 45*2 = 900 - 90 = 810

a-45×2=900

a = 900 + 45*2 = 900 + 90 = 990

Answer 3

To solve each of these equations, we need to find the values of the variables involved. Let's go through them one by one:

1. 45×2×y = 900 We want to find the value of 'y'. To do that, we need to isolate 'y' on one side of the equation. Divide both sides by (45×2) to solve for 'y':

45×2×y = 900 y = 900 / (45×2) y = 900 / 90 y = 10

So, the value of 'y' is 10.

2. 45×2 + b = 900 Now, we want to find the value of 'b'. Again, we need to isolate 'b' on one side of the equation. Subtract 45×2 from both sides:

45×2 + b = 900 b = 900 - (45×2) b = 900 - 90 b = 810

So, the value of 'b' is 810.

3. a - 45×2 = 900 Finally, we want to find the value of 'a'. To do that, isolate 'a' on one side of the equation. Add 45×2 to both sides:

a - 45×2 = 900 a = 900 + (45×2) a = 900 + 90 a = 990

So, the value of 'a' is 990.

To summarize: y = 10 b = 810 a = 990
