Abelardo had 3 bags of apples. He gave 2 to his best friend, he gave 3 to his brother, and he fed 1 to his horse. On the way hom

dimaraw [331]

Answer:

number of apples he originally had in each bag was 14 apples

Step-by-step explanation:

We are told that he had 3 bags of apples.

Now, let amount of apples in one bag be x.

Thus, total amount of apples is 3x.

We are told he gave 2 apples to his best friend, he gave 3 to his brother, and he fed 1 to his horse.

This means total given out = 2 + 3 + 1 = 6 apples.

Then, on the way home, he was chased by some dogs and dropped 1 bag.

Thus, amount of apples dropped is 1x = x

Thus;

Amount left on getting home after the entire giving and dropping is;

3x - 6 - x = 2x - 6

Now,we are told that he had 22 apples left when he got home.

Thus;

2x - 6 = 22

2x = 22 + 6

2x = 28

x = 28/2

x = 14 apples

Thus, number of apples he originally had in each bag was 14 apples

If trap is an isosceles trapezoid, what is the value of x

Burka [1]

Answer:

Option E ⇒ <u>x = 19</u>

Step-by-step explanation:

See the attached figure.

TRAP is an isosceles trapezoid

The shown angles are supplementary angles

So, the sum of (5x+9) and (4x) is 180

So, 5x+9 + 4x = 180

solve for x

9x + 9 = 180

9x = 180-9 = 171

x = 171/9 = 19

The answer is <u>option E</u>
