How do i solve this equation: 4/5a + 3 = 1/3a - 8
DENIUS [597]
You have to subtract by \frac{1}{3}a on EACH of  the sides you're working with!

\frac{4}{5}a + 3 - \frac{1}{3}a - 8 - \frac{1}{3}a

Which gives us: \frac{7}{15}a + 3 = -8

Now, that we got these steps out of the way, let's subtract 3 from the sides you're working with! 

\frac{7}{15}a  + 3 - 3 \\ = -8 -3

 \frac{7}{15}(a) = -11

We have gotten these  steps out of the way now lets multiply by \frac{15}{7} on your sides because, it is the reciprocal of \frac{7}{15}

So,  \frac{15}{7}( \frac{7}{15}a ) =  \frac{15}{7}  (-11)

Cancel out: \frac{15}{7}( \frac{7}{15} ) because, it equals to:1

\frac{15}{7}(-11) =   \frac{-165}{7}

Therefore, your answer is:  \frac{-165}{7} aka 23\frac{4}{7} 

Good luck on your assignment and enjoy your day

When instructed to find the length of HJ in right
kobusy [5.1K]

See attachement for the diagram of the triangle

Answer/Step-by-step explanation:

To find the length of HJ, we can use different equations as follows:

✔️Recall: SOHCAHTOA

Let's take <G as the reference angle = 28°

Opposite side to reference angle = HJ

Hypotenuse = 20

Apply SOH.

Thus:

Sin 28° = opp/hyp

Sin 28° = HJ/20 (Alex's equation is correct).

Solving further, we would have:

HJ = Sin 28 * 20 ≈ 9.4

✔️Another way is by using <H as the reference angle.

m<H = 180° - (90° + 28°) (sum of triangle)

m<H = 62°

Adjacent side to reference angle (<H) = HJ

Hypotenuse = 20

Apply CAH:

Cos 62° = Adj/Hyp

Cos 62° = HJ/20 (Marlene's equation is correct)

Solving further, we would have,

HJ = Cos 62° * 20 ≈ 9.4

As you can see, the equation of both students are correct. Both would arrive at the same answer using any of the two equations.
