in the ambrose family the ages of the three children are three consecutive even integers . if the age of the youngest child is r

klemol [59]

The ages are consecutive even numbers.
The youngest child is (x+3) years old.
Every even number is 2 more than the one before it.
So the three ages are

   (x + 3), (x + 5), and (x + 7).

Their sum is x+3 + x+5 + x+7 = 3x + 15

But we're told that their sum is 42, so we can write

      3x + 15 = 42 <== the equation

Subtract 15 from each side: 3x   = 27

Divide each side by 3 : x   =   9 <== the solution

So the three ages are 12, 14, and 16.

The oldest child is 16 years old.

phoebe needs to use 3/4 cup to make one batch of cookies how many batches can she make with 12 cups of sugar?

sattari [20]

$\bf \begin{array}{ccll}\stackrel{sugar}{cups}&\stackrel{cookies}{batches}\\\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\\frac{3}{4}&1\\\\12&b\end{array}\implies \cfrac{\quad \frac{3}{4}\quad }{12}=\cfrac{1}{b}\implies \cfrac{\quad \frac{3}{4}\quad }{\frac{12}{1}}=\cfrac{1}{b}\\\\\\\cfrac{3}{4}\cdot \cfrac{1}{12}=\cfrac{1}{b}\implies \cfrac{3}{48}=\cfrac{1}{b}\implies 3b=48\implies b=\cfrac{48}{3}\implies b=16$
