Question

9,5b+6,3+b-4,75 при b =1,4

Answer 1

вот так )) получится 16,25

Answer 2

$9.5 \times 1.4 + 6.3 + 1.4 - 4.75 = 13.3 + 7.7 - 4.75 = 16.25$

Answer 3

To evaluate the expression 9.5b + 6.3 + b - 4.75 when b = 1.4, you simply substitute the value of b into the expression and perform the calculations:

9.5(1.4) + 6.3 + 1.4 - 4.75

Now, follow the order of operations (PEMDAS/BODMAS):

1. Perform the multiplication: 9.5 * 1.4 = 13.3
2. Add the results: 13.3 + 6.3 + 1.4 - 4.75

Now, continue with the addition and subtraction:

13.3 + 6.3 + 1.4 - 4.75 = 16.3

So, when b = 1.4, the expression evaluates to 16.3.
