Which expression is not equivalent to the other expressions?

1 answer:

4 0

-6(2x - 4) = -6*(2x) -6*(-4) = -12x + 24

-(12x - 6) + 18 = -12x + 6 + 18 = -12x + 24

-3(4x - 3) + 15 = -3*(4x) -3*(-3) + 15 = -12x + 9 + 24 = -12x + 24

-4(3x + 6) = -4*(3x) -4*(6) = -12x -24

All the expressions gave the same answer as -12x + 24, except for the last expression.

So, -4(3x + 6) is not equivalent to the others.

The camp cook made 1 1/2 pints of baked beans. Each serving of beans is 3/10 of a pint. How many servings of beans did the cook

Marta_Voda [28]

Answer:
number of servings = 5 servings

Explanation:
We are given that each serving is 3/10 of a pint. To know the number of servings of 1.5 pints, we will simply use cross multiplication as follows:

1 serving ....................> 3/10 pint
?? servings ................> 1.5 pints

number of servings = (1.5*1) / (3/10)
number of servings = 5 servings

Hope this helps :)
