-x - 2 = -44 + 5 Not sure how to do this

1 answer:

5 0

   -x - 2 = -44 + 5

That mess on the right side is just (5 - 44), which is -39 .
So now the equation is
        -x - 2   = -39

Add 2 to each side:     -x    = -37

Multiply each side by -1 : x    =   37

Please can someone help me solve 10x+5=15

telo118 [61]

Answer: The value of x is 1

Step-by-step explanation:

10x + 5 = 15

Collect the like terms which in this case are the whole numbers "5" and "15")

10x = 15 - 5

10x = 10

Divide both sides by 10

10x/10 = 10/10

x = 1

Thus, the value of x is 1

In ΔJKL, k = 3.7 cm, ∠K=15° and ∠L=41°. Find the length of j, to the nearest 10th of a centimeter.

Alexandra [31]

Answer:

The length of side j is 11.85cm

Step-by-step explanation:

Given that

In triangle JKL,

$\angle k=15$

$\angle l=41$

Side k=LJ=3.7cm

To find side j=KL:

By using sine rule,

We can write as

$\frac{SinK}{LJ} = \frac{SinL}{JK} = \frac{SinJ}{KL} \\\frac{Sin15}{3.7} = \frac{Sin41}{JK} = \frac{SinJ}{KL}$

Using property of triangle,

$\angle k+\angle l+\angle j=180$

$15+41+\angle j=180$

$\angle j=124$

$\frac{Sin15}{3.7} = \frac{Sin41}{JK} = \frac{Sin124}{KL}\\\frac{Sin15}{3.7} = \frac{Sin124}{KL}\\KL=3.7\frac{Sin124}{Sin15}\\KL=3.7\frac{0.8290}{0.2588}\\KL=11.85cm$

Thus,

The length of side j is 11.85cm
