Question

2,4y+8,75y-4y=? Если y =1000

Answer 1

6,790 решение:2,4у+8,75у=10,79у-4у=6,79×1000=6,790

Answer 2

To find the value of the expression 2(4y) + 8.75y - 4y when y = 1000, simply substitute the value of y into the expression and perform the calculations:

Step 1: Substitute y = 1000 into the expression: 2(4y) + 8.75y - 4y = 2(4 * 1000) + 8.75 * 1000 - 4 * 1000

Step 2: Perform the calculations: 2(4 * 1000) = 2(4000) = 8000 8.75 * 1000 = 8750 4 * 1000 = 4000

Now, we have: 8000 + 8750 - 4000

Step 3: Calculate the final result: 8000 + 8750 - 4000 = 12750

So, when y = 1000, the value of the expression is 12750.
