Question

Evaluate the expression 7(3-2w) +2-3 where w =5.

Answer 1

7(2-3w)+2-3 when w=5

7(2-(3×5))-1

7(2-15)-1

7(-13)-1

-91-1=-92

Answer 2

So, when w = 5, the expression 7(3 - 2w) + 2 - 3 evaluates to -50.

Explanation:

To evaluate the expression 7(3 - 2w) + 2 - 3 when w = 5, you need to substitute the value of w into the expression and then simplify:

7(3 - 2w) + 2 - 3

First, substitute w = 5:

7(3 - 2(5)) + 2 - 3

Now, perform the arithmetic operations:

7(3 - 10) + 2 - 3

Inside the parentheses:

7(-7) + 2 - 3

Now, multiply 7 by -7:

-49 + 2 - 3

Next, combine like terms:

(-49 + 2) - 3

Now, add -49 and 2:

-47 - 3

Finally, subtract 3 from -47:

-47 - 3 = -50

So, when w = 5, the expression 7(3 - 2w) + 2 - 3 evaluates to -50.
