EVALUATE 6a + 4b - 3c WHEN a=4, b=7, AND c= -2
And your answer is?
6(4)+4(7)-3(-2)=
24+28+6= 58
To evaluate the expression 6a + 4b - 3c when a=4, b=7, and c=-2, substitute these values into the expression and simplify:
6a + 4b - 3c
= 6(4) + 4(7) - 3(-2) (substituting a=4, b=7, and c=-2)
= 24 + 28 + 6 (multiplying)
= 58 (simplifying)
Therefore, when a=4, b=7, and c=-2, the expression 6a + 4b - 3c evaluates to 58.
To evaluate the expression 6a + 4b - 3c when a = 4, b = 7, and c = -2, you simply substitute the given values into the expression and perform the arithmetic.
First, let's substitute the values into the expression:
6a + 4b - 3c = 6(4) + 4(7) - 3(-2)
Next, we simplify each term:
6(4) = 24
4(7) = 28
-3(-2) = 6 (remember, a negative multiplied by a negative gives a positive result)
Now, we substitute the simplified values back into the expression:
6a + 4b - 3c = 24 + 28 + 6
Finally, we add the numbers together:
24 + 28 + 6 = 58
Therefore, when a = 4, b = 7, and c = -2, the expression 6a + 4b - 3c equals 58.
