Answer:

$150

Step-by-step explanation:

5% of $120 is $6 and 20% is $24.

$6(tax) + $24(tip) + $120(original) = $150

Answer:

$150

Step-by-step explanation:

Additional 5% and 20% on the original cost is additional 25%

Total cost = 125% of 120

= (125/100)×120

= 150

If 5(3x-1)=55 what is the value of 2x-2

cricket20 [7]

Hey ! there

Answer:

Value of 2x - 2 is 6 .

Step-by-step explanation:

In this question we are provided with an equation that is 5 ( 3x - 1 ) = 55 and we are asked to find the value of 2x - 2 .

Firstly , we need to find the value of x . So we need to solve the equation .

SOLUTION : -

$\quad \longmapsto \qquad \: 5(3x - 1) = 55$

Step 1 : Dividing with 5 on both sides :

$\quad \longmapsto \qquad \: \dfrac{ \cancel{5}(3x - 1)}{ \cancel{5}} = \cancel{\dfrac{55}{5} }$

On cancelling , We get :

$\quad \longmapsto \qquad \:3x - 1 = 11$

Step 2 : Adding 1 on both sides :

$\quad \longmapsto \qquad \:3x - \cancel{1} + \cancel{1} = 11 + 1$

On simplifying , We get :

$\quad \longmapsto \qquad \:3x = 12$

Step 3 : Dividing with 3 on both sides :

$\quad \longmapsto \qquad \: \dfrac{ \cancel{3}x}{ \cancel{3}} = \cancel{ \dfrac{12}{3} }$

We get ,

$\quad \longmapsto \qquad \: \underline{\boxed{\frak{x = 4}}}$

→ Therefore , value of x is 4 .

Verifying : -

Now we are verifying whether our answer is wrong or right . So ,

5 ( 3x - 1 ) = 55

5 { 3( 4 ) - 1 } = 55

5 ( 12 - 1 ) = 55

5 ( 11 ) = 55

L.H.S = R.H.S

Hence , Verified .

Therefore , our value of x is correct/valid .

We need to find the value of 2x - 2 . 

 $\quad \longmapsto \qquad \:2x - 2$ 

So substituting value of x in it :

 $\quad \longmapsto \qquad \:2( \bold{4}) - 2$ 

Multiplying 2 with 4 : 

 $\quad \longmapsto \qquad \:8 - 2$ 

Subtracting 2 from 8 :

$\quad \longmapsto \qquad \: \blue{\underline{\boxed{\frak{6}}}} \quad \: \bigstar$

Henceforth, value of 2x - 2 is ❝ 6 ❞.

NEEP HELP TODAY OR ASAP PLEASE!!!!!

dmitriy555 [2]

Answer:

133

Step-by-step explanation:

The two angles add to a straight line

PQR + RQS = PQS

3x-5 + x+1 = 180

Combine like terms

4x -4 =180

Add 4 to each side

4x -4+4 = 180+4

4x =184

Divide each side by 4

4x/4 =184/4

x =46

We want to find PQR

PQR = 3x-5

= 3*46 - 5

= 138 -5

= 133

Mr. and Mrs. Preston and their two children are very excited about their upcoming

ki77a [65]

Answer:

They will spend less at the sunny side hotel

Step-by-step explanation:

The attachment completes the question.

From the question, we understand that there are 4 individuals involved.

Mr. Preston (1)
Mrs. Preston (1)
The children (2)

And they will spend one night

First, we need to calculate the expenses in Traveler's hotel.

$Rate = \$107.10$ (for 3 people)

$Additional\ Person = \$21.55$ (for 1 person)

$Breakfast = \$8.75 * 4$ (for 4 people)

$Tax = \$16.85$

Total Expenses

$Total = \$107.10 + \$21.55 + \$8.75* 4 + \$16.85$

$Total = \$107.10 + \$21.55 + \$35.00 + \$16.85$

$Total = \$108.50$

For Sunny Side hotel:

$Rate = \$152.95$ (for 4 people)

$Tax = \$21.34$

Total Expenses:

$Total = \$152.95 + \$21.34$

$Total = \$174.29$

By comparison, they will spend less at the sunny side hotel.
