The max of Lauren's age --> the minimum of the others' ages, 1, 2 & 3

4*avg = 4*9 = 36

36 - (1+2+3) = 30

Lauren is 30 yrs of age, or younger.

Ben has 2 identical pizzas.
Varvara68 [4.7K]
Let the weight if a whole pizza be x grams

Then 1/4 of a pizza weighs x/4  grams and one eighth weighs x / 8.  The difference is 32 grams so we can make the following equation:-

x/4 - x/8  = 32
x / 8  = 32
Multiplying both sides by 8:-

x = 8*32 =  256 

Answer is 256 grams.

What is the anser to the equation 2^{2x+2} = 2^{3x}
Marianna [84]

Answer: C) x = 2

2^{2x + 2} = 2^{3x}

Since both terms (above) have the same base, set the exponents to be equal:

2x + 2 = 3x (Rearrange to solve for x)

x = 2

∴ x = 2
