Бардык белгилүү авиация мыйзамдарына ылайык, аары учуу мүмкүнчүлүгү жок.

Step-by-step explanation:

Бардык белгилүү авиация мыйзамдарына ылайык, аары учуу мүмкүнчүлүгү жок. Канаттары өтө эле кичинекей, семиз денесин чече албайт. Албетте, аары баары бир учат. Себеби аарылар адам мүмкүн эмес деп эсептеген нерсеге маани бербейт.

Answer:

Mean = 19.5

Step-by-step explanation:

Mean = sum of numbers ÷ Amount of numbers

Mean = $\frac{16+17+17+17+17+19+19+19+19+21+22+22+23+25}{14}$

Mean = $\frac{273}{14}$

Mean = 19.5

50 per cup. If we plug this in to each equation, you'll see that 12 granola bars equals $12, and 7 cups of yogurt equals $3.50, for a total of $15.50.

Answer:

Train A - 50 miles per hour

train B - 30 miles per hour

Step-by-step explanation:

Let x mph be the speed of the train B, then the speed of the train A is (x+20) mph.

In 3 hours,

train A travels 3(x+20) miles
train B travels 3x miles

In total, they covered the distance of 240 miles, so

$3(x+20)+3x=240\ \ \ \text{[Divide by 3]}\\ \\x+20+x=80\\ \\2x=80-20\\ \\2x=60\\ \\x=30\ mph\\ \\x+20=30+20=50\ mph$

Answer:

x = 15

Explanation:

First, add both equations on one side, and set it equal to 180° because it's supplementary:

2x + 8 + 8x + 22 = 180

combine like terms:

10x + 30 = 180

subtract 30 on both sides of the equation and you end up with:

10x = 150

divide both sides by 10 and you get:

x = 15
