X – 10y = 18 -6x – 10y = 32

Mathematics
1 answer:
viva [34]3 years ago
8 0

Answer:

Step-by-step explanation:

x - 10y = 18

-6x - 10y = 32

Since both equations have -10y, we can subtract the second equation from the first to try and solve for x:

(x - 10y) - (-6x - 10y) = 18 - 32

x - 10y + 6x + 10y = -14

7x = -14

x = -2

With this, we can plug the value back into the first equation to solve for y:

(-2) - 10y = 18

-2 - 10y = 18

-10y = 20

y = -2

Therefore, the solution is x = -2, y = -2

svetoff [14.1K]

Answer:

C. 5 goes into 100 twenty times, and 1 times 20 is 20

Step-by-step explanation:

Since, we know that when we multiply both numerator and denominator of a fraction by a same number then we obtain an equivalent fraction,

Here, the given fraction,

\frac{1}{5}

By the above statement,

\frac{1}{5}=\frac{1\times 20}{5\times 20}=\frac{20}{100}

Now,

a\%=\frac{a}{100}

\implies \frac{20}{100}=20\%

Hence,

\frac{1}{5}=20\%

Option C is correct.

An airplane travels about 1,500 Km in a straight line between Toronto and Winnipeg. However, the plane must climb to 10,000 m du
Anna007 [38]

Answer:416

Step-by-step explanation: Based on the given problem above, it requires a trigonometric solution. So here it goes:

The climb distance is:200 * Sec [ArcTan [10/200]] = 10√ 401 km

and the decent distance is:300 * Sec [ArcTan [10/300]] = 10√901 km

So add the given results above with 500 km and this will be the additional distance that plane moves through the air.

The answer would be in the unit meters.

((10√401 +10√901−500)∗1000)=416 meters

Hope this is the answer that you are looking for.
