X=-16 -2(2x+5)-3=-3(x-1) (-4x-10)-3=-3x+3 -4x-13=-3x+3 Move -13 to the right side by adding it to +3 and itself to cancel the original -13 out, and move -3x to the left side by adding it to -4x and itself to cancel the original -3x out -4x+3x=3+13 -1x=16 Divide -1 from both sides x=-16

- - Solve for "x"

Steps:
You need to simplify for both sides of your equation
Then add your "3x" to both of the sides of the problem
Now add 13 to both sides
and then final step is to divide both sides by "-1"

Final answer:

x= -16

2. Solve the following equations for 0° Sx < 180°.

diamong [38]

Answer:

See below in bold.

Step-by-step explanation:

(1) cosec ( x + 10) = 3

Now cosec x = 1/sin x so

1 / sin (x + 10) = 3

3 sin (x + 10) = 1

sin (x + 10) = 1/3

x + 10 = 19.47 , 160.53 degrees

x = 9.47, 150.53 degrees.

(ii) cot (x - 30) =0.45

cot (x - 30)= 1 /tan (x- 30) so we have

tan (x - 30) = 1 / 0.45 = 2.2222

x - 30 = 65.77 degrees

x = 95.77 degrees.

At what value of x do the graphs of the equations below intersect?

Bogdan [553]

Answer:

Step-by-step explanation:

The intersection is the point where two equations meet. It is calculated by substituting terms into the equations involved. For the given systems of equation, calculations are as follows:

2x - y = 6

y = 2x - 6

We substitute the equation above to the second equation.

5x + 10y = –10

5x + 10( 2x - 6 )= –10

Simplifying,

5x + 20x - 60 = -10

25x = 50

x = 2

Therefore, the intersection has the value of x equal to 2.

You have $200 in a savings account.Each week for 8 weeks,you take out $18 for spending money.How much money is in your account a

g100num [7]

The amount of money in your account is mathematically given as

x = $56

This is further explained below.

<h3>What is an account?</h3>

Generally, An account is a term used in accounting to refer to assets, liabilities, income, costs, and equity.

In bookkeeping, an account is represented by a single page in a ledger, and any changes in value are chronologically documented using debit and credit entries.

These entries, which are also known as posts, are added to a book of final entries or ledger and form a part of it.

In conclusion, the amount of money in your account will be

18 * 8 = 144

Therefore

x=200 - 144

x = $56
