Answer:

X= -10 | Hope this helped! :')

<u>Steps for answer!</u>

1. Divide both sides by -2.

x+27=-34/-2

2. Two negatives make a positive.

x+27=34/2

3. Simplify  34/2 to  17.

x+27=17

4. Subtract 27 from both sides.

x=17-27

5. Simplify  17-27 to  -10.

x=-10

---------------------

<u>Checking answer:</u>

−2(x+27)=−34

1. Let x=−10.

−2×(−10+27)=−34

2. Simplify  -10+27 to  17.

−2×17=−34

3. Simplify  -2 x 17  to  -34.

-34=-34

Please show me step by step on how to solve this.

Well, you have to be given an interval. That is not an interval.

You should be given something like 1 \leq x \leq 2

If you add those fractions up you'll just get a point on the number line.

Find the LCD for all of them which is 9/6 - 4/6 + 3/6 = 8/6 = 2/3

You'll end up with a point on 2/3

please help :{ brainliest if you can get it right and I need you to prove why your answer is correct, thanksss​

Answer:

The Value of a=\frac{15}{4}.

Step-by-step explanation:

We have Named the figure please find the attachment for your reference.

Given:

PR = y

QR = a

RS = b

PS = z

PQ = x

QS = 15

∠P = 90°

∠R = 90°

∠Q = 60°

∠S = 30°

We need to find the Value of 'a'.

Solution:

Now we know that:

In Δ PQS

∠P = 90°

∠S = 30°

Now we know that;

sin\ \theta = \frac{opposite\ side}{Hypotenuse}

sin \ S= \frac{PQ}{QS}

Substituting the given values we get;

sin\ 30\°=\frac{x}{15}

Now we know that;

sin\ 30\° = \frac12

So we can say that;

\frac{1}{2}=\frac{x}{15}\\\\x=\frac{15}{2}

Now In Triangle PQR.

∠R = 90°

∠Q = 60°

So we can say that;

Cos \theta = \frac{adjacent \ Side}{Hypotenuse}\\

Cos\ Q = \frac{QR}{PQ}

Substituting the given values we get;

cos 60\°= \frac{a}{x}

Now we know that;

cos 60\°= \frac12

x=\frac{15}{2}

So substituting the values we get;

\frac{1}{2}=\frac{a}{\frac{15}{2}}

By Using Cross Multiplication we get;

a= \frac{1}{2}\times\frac{15}{2}\\\\a=\frac{15}{4}

Hence The Value of a=\frac{15}{4}.
