Find the value of x.l

Answers

Answer:

The value of x is 28°

Step-by-step explanation:

2x + 1 and 33° together forms 90° angle.

So, we need to find the angle at the 2x + 1.

--> 90° - 33°

= 57°

So, 2x + 1 gives 57°.

So, to find x :-

2x + 1 = 57°

2x = 57 - 1

2x = 56

x = [tex]\frac{56}{2}[/tex]

x = 28

The clock one is 20 because there are 4 weeks past and you would just plug that into the equation. The catering one is 118 , also plugging into the equation given.

Answer:

The first question provided (question 11)

The answer is $118.00

The second question provided (question 12)

The answer is 20 seconds

Step-by-step explanation:

The first question provided (question 11)

The equation 5a + 3c is provided to determine the cost of a catering event, where a is the number of adults and c is the number of children.

It is stated that there are 17 adults and 11 children attending an event.

You can substitute in the 17 adults in place of a and the 11 children in place of c.

This will leave you with 5(17) + 3(11).

If you simplify you will get 85 + 33, which is equal to 118

Therefore, the answer is $118.00.

The second question provided (question 12)

The equation s = 5w is provided to determine how far behind a clock is after a certain amount of time, where s is seconds behind and w is the number of weeks sice the clock was last set.

You are given the clock was set 4 weeks ago.

You can subsitute the 4 weeks into the equation in place of variable w.

This leaves you with s = 5(4).

Simplifying this further, you will get s = 20.

Therefore, the clock is 20 seconds behind.

2 - x = x - 8

ayudaaa
porfavor

Answers

Answer:

x=5

Step-by-step explanation:

2 - x = x - 8

- x = x - 8 - 2 (subtract 2 from both sides)

- x = x - 10 (combine like terms)

- 2x = - 10 (subtract x from both sides)

x = 5 (divide each side by -2).

Answer:

x = 5

Step-by-step explanation:

2 - x = x - 8

- x + 2 = x - 8

- x + 2 - 2 = x - 8 - 2

- x = x - 10

- x - x = x - x - 10

- 2x = - 10

- 2x ÷ - 2 = - 10 ÷ - 2

x = 5
