Answer:

-  \frac{1}{5}  -  \frac{4}{9} a =  \frac{2}{15}

-  \frac{4}{9} a =  \frac{2}{15}  +  \frac{1}{5}  \\  \\  -  \frac{4}{9} a =  \frac{1}{3 }  \\  \\  ( - 4 \times 3)a = (1 \times 9) \\  - 12a = 9 \\ a =   - \frac{9}{12}  \\  \\ { \underline{ \:  \: a =   - \frac{3}{4}  \:  \: }}

Consider the system of equations:
vodka [1.7K]

Answer:

(x, y) = (5, 1)

Step-by-step explanation:

To <em>eliminate</em> x, you can double the second equation and subtract the first.

... 2(x +4y) -(2x -3y) = 2(9) -(7)

...11y = 11 . . . . . simplify

... y = 1 . . . . . . divide by 11

Using the second equation to find x, we have ...

... x + 4·1 = 9

... x = 5 . . . . . subtract 4

_____

<u>Check</u>

2·5 -3·1 = 10 -3 = 7 . . . . agrees with the first equation

(Since we used the second equation to find x, we know it will check.)

Can any one explain this question worth points! plz explain if you can
creativ13 [48]

Answer:

x = 31

Step-by-step explanation:

The given angles are supplementary and their sum is 180 degrees

5x - 16 + x + 10 = 180 add like terms

6x - 6 = 180 add 6 to both sides

6x = 186 divide both sides by 6

x = 31

Liam has a bag that contains pineapple chews, cherry chews, and lime chews. He
dsp73

The probability that the next chew Liam removes from the bag will be a cherry chew is 0.03.

<h3>What is probability?</h3>

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

We have:

Liam performs the experiment 62 times

Total number of outcomes = 62

A pineapple chew was selected 58 times.

A cherry chew was selected 2 times.

A lime chew was selected 2 times.

Now, the probability that the next chew Liam removes from the bag will be cherry chew:

P = 2/62

P = 1/31

P = 0.0322  or 0.03

Thus, the probability that the next chew Liam removes from the bag will be a cherry chew is 0.03.

Find x round to the nearest tenth! please help!!! more trigonometry!​
hoa [83]

Answer:

<h2>x = 437.3 ft</h2>

Step-by-step explanation:

Look at the picture.

Use cosine:

cosine=\dfrac{adjacent}{hypotenuse}

We have a measure of the angle and length of the hypotenuse:

\alpha=29^o,\ hypotenuse=500\ ft

\cos29^o\approx0.87461

Substitute:

\dfrac{y}{500}=0.87461                 <em>multiply both sides by 500</em>

y=437.305\to y\approx437.3
