Greeley [361]

Answer:

12\dfrac{1}{8}\ feet

Step-by-step explanation:

Sonya drops a marble while standing on a deck 7 \dfrac{7}{8} feet above the ground.

The marble falls 4 \dfrac{1}{4} feet from Sonya's hand to the deck, and then rolls and falls to the ground.

So, the ball falls 4 \dfrac{1}{4} feet from Sonya's hand to the deck  and 7 \dfrac{7}{8} from the deck to the ground, in total

4\dfrac{1}{4}+7\dfrac{7}{8}=4\dfrac{2}{8}+7\dfrac{7}{8}=(4+7)+\dfrac{2+7}{8}=11+\dfrac{9}{8}=11+1\dfrac{1}{8}=12\dfrac{1}{8}\ feet

A snack tray at a party has cheese squares with 2 grams of protein apiece and turkey slices with 3 grams of protein apiece. Whic
Andreyy89

Answer:

The inequality equation is 12 ≤ 2x + 3y

Step-by-step explanation:

Protein in a cheese square = 2 grams

Protein in a turkey square = 3 grams

And She can eat 12 or more grams of proteins

Let x be the number of cheese squares and y be the number of turkey squares that she eats.

So, we can write an inequality equation, that describes the given situation in the problem.

i.e. 2x + 3y ≥ 12  or 12 ≤ 2x + 3y

So the inequality equation is 12 ≤ 2x + 3y
