If -3y+5=-4 find the value of 5y

1 answer:

6 0

-3y + 5 = -4 Subtract 5 from both sides
-3y = -9 Divide both sides by -3
y = 3

Now, plug that into 5y

5y Plug in 3
5(3) Multiply
15

5y = 15

The following table shows the salary of 7 people in an office last year.

kotegsom [21]

Answer:

a. £24,714.29

b. £16,833.33

Step-by-step explanation:

The calculation of mean income is given below:-

Mean income = Total addition of salaries ÷ Number of workers

= £9,500 + £25,000 + £13,250 + £72,000 + £12,750 + £29,500 + £11,000

= £173,000 ÷ 7

= £24,714.29

Now,

the Mean income excluding Deva's salary:

= Formula of Mean income

= Total addition of salaries excluding Deva salary ÷ Number of workers

= (£9,500 + £25,000 + £13,250 + £12,750 + £29,500 + £11,000) ÷ 6

= £101,000 ÷ 6

= £16,833.33

What is the measure of Angle J K L? Triangle J K L . The exterior angle to angle K has a measure of 83 degrees. 83 degrees 97 de

nasty-shy [4]

Answer:

The measure of angle JKL is 97 degrees.

Step-by-step explanation:

Given:

A triangle JKL .

Measure of exterior angle K = 83 degrees

We have to find the measure of $\angle JKL$ .

In $(\triangle\ JKL)$ we see that the exterior angle is in linear pair with $\angle JKL$ .

Note:

Linear pair angles sum is 180 degree.

Let $\angle JKL$ be 'x' degrees .

So,

⇒ $x+83=180$

⇒ <em>Subtracting 83 from both sides.</em>

⇒ $x+83-83=180-83$

⇒ $x=180-83$

⇒ $x=97$ degrees

The measure of angle JKL in the triangle is of 97 degrees.
