Question

M=3/2, то 8m-7/3+2m

Answer 1

$\frac{8* \frac{3}{2}-7 }{3+2* \frac{3}{2} } = \frac{4*3-7}{3+3} = \frac{5}{6}$

Answer 2

To evaluate the expression 8m - 7/3 + 2m when m = 3/2, we substitute the value of m into the expression:

m = 3/2

8m - 7/3 + 2m = 8 * (3/2) - 7/3 + 2 * (3/2)

Now, let's calculate the result step by step:

8 * (3/2) = 24/2 = 12

2 * (3/2) = 6/2 = 3

Now, we have:

12 - 7/3 + 3

To add the fractions, we need a common denominator. The common denominator for 3 and 3 is 3. So, we rewrite 12 as 36/3.

36/3 - 7/3 + 3

Now, we can combine the fractions:

(36 - 7)/3 + 3 = 29/3 + 3

To add the fractions, again we need a common denominator. The common denominator for 3 and 3 is 3.

(29 + 3)/3 = 32/3

So, when m = 3/2, the expression 8m - 7/3 + 2m equals 32/3.
