Question

Вычисли значения вырожения 4b-3c,если b=9и c=0,8

Answer 1

4b-3c

4*9-3*0,8=36-2,4=33,6

Answer 2

4b-3c=4*9-3*0,8=36-2,4=33,6

Answer 3

To compute the value of the expression 4b - 3c when b = 9 and c = 0.8, you simply substitute the given values into the expression and perform the arithmetic operations. Here's how you do it:

4b - 3c = 4 * b - 3 * c

Substitute b = 9 and c = 0.8 into the expression:

4 * 9 - 3 * 0.8

Now, calculate the result:

4 * 9 = 36 3 * 0.8 = 2.4

So, the final result is:

36 - 2.4 = 33.6

The value of the expression 4b - 3c, when b = 9 and c = 0.8, is 33.6.
