Question

7,5m+3.8m-4/2 при m=10

Answer 1

7,5 * 10 + 3,8 *10 - 4/2=111
1. 7,5 * 10= 75
2. 3,8 * 10=38
3. 4/2= 2
4. 75+38= 113
5. 113-2=111

Answer 2

7.5*10+3.8*10-4/2
75+38-4/2
111

Answer 3

To evaluate the expression 7.5m + 3.8m - 4/2 when m is equal to 10, follow these steps:

1. Replace the variable "m" with the value 10.
2. Perform the calculations according to the order of operations (PEMDAS/BODMAS), which stands for Parentheses/Brackets, Exponents/Orders, Multiplication/Division, and Addition/Subtraction.

Let's proceed with the calculations:

Step 1: Replace m with 10: 7.5(10) + 3.8(10) - 4/2

Step 2: Perform the operations from left to right:

7.5(10) = 75 3.8(10) = 38 4/2 = 2

Now the expression becomes: 75 + 38 - 2

Step 3: Now add and subtract from left to right:

75 + 38 = 113 113 - 2 = 111

So, the result of the expression 7.5m + 3.8m - 4/2 when m is equal to 10 is 111.
