Question

2 5/7p+3 1/2 при р =7

Answer 1

2 5/7 ×7 +3 1/2= 19+3 1/2= 22 1/2

Answer 2

To find the value of the expression 2(5/7)p + 3(1/2) when p = 7, you need to substitute p with 7 and then perform the calculations. Here's how you can do it step-by-step:

Step 1: Substitute p with 7. 2(5/7)p + 3(1/2) = 2(5/7)(7) + 3(1/2)

Step 2: Simplify the expressions inside the parentheses. 2(5/7)(7) = 2(5) = 10 3(1/2) = 3/2

Step 3: Perform the final calculations. 10 + 3/2 = 10 + 1.5 = 11.5

So, when p = 7, the value of the expression is 11.5.
