I'm confused on this problem 2/3x-1=5

Answers

Answer 1

Answer:

x=9

Step-by-step explanation:

2/3x-1=5

Add 1 to each side

2/3x-1+1= 5+1

2/3x = 6

Multiply each side by 3/2

2/3x*3/2 = 6*3/2

x = 9

Answer 2

Answer:

x=9

Step-by-step explanation:

You add one to both sides, multiply 3 to both sides (to further isolate x), and then divide by 2 on both sides. When you substitute back in, both sides of the equation are equal to each other.

Carrie and nine of her friends go out to dinner. The total bill comes to $200. They decide to leave a 15% tip. Each person will contribute an equal amount to the total tip. What each person should contribute

Answers

Answer:

$3

Step-by-step explanation:

To find the value of the tip, multiply 200 by 15%.

200 x 15% = 30

Divide the tip by the number of people at the dinner (Carrie plus 9 friends = 10 people)

30 / 10 = 3

Each person should contribute $3 toward the tip.

Each person will contribute $23.

What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

Total Bill= $200

Tip= 15%

So, the amount of bill be paid after tip

= 200+ 200 x 15%

= 200+ 200 x 15/100

= 230

Now, each of them have to pay

= 230/ 10

= $23

Hence, Each of them paid $23.

Answer:

x = 25

Step-by-step explanation:

3x + 5 + 5x - 25 = 180 (collect like terms)

8x - 20 = 180 (add 20 on both sides)

8x = 200 (divide by 8 on both sides)

x = 25

Since they are supplementary that mean together they add up to 180 so that's why I added them together.

f(x) = 3x + 2
g(x) = 2x^2 - 4x
h(x) = x^2 - x + 7

Find f[g(5)]

A. 92
B. 2
C. 30
D. 242

Answers

Answer:

A

Step-by-step explanation:

Evaluate g(5), then use the value obtained to evaluate f(x) , that is

g(5) = 2(5)² - 4(5) = 2(25) - 20 = 50 - 20 = 30, then

f(30) = 3(30) + 2 = 90 + 2 = 92

Find the value of x. Draw a triangle and label each interior angle before solving.
Then find the angle measures of the polygon.

Angle one: 2x°, angle two: xº, angle 3: (X + 8)°

Answers

Sum of all angles in a triangle = 180°

Which means :-

∠1 + ∠2 + ∠3 = 180°

[tex]2x + x + x + 8 = 180°[/tex]

[tex]4x + 8 = 180°[/tex]

[tex]4x = 180 - 8[/tex]

[tex]4x = 172[/tex]

[tex]x = \frac{172}{4} [/tex]

[tex]x = 43[/tex]

Angle 1 :-

= 2x

= 2 × 43

= 86°

Angle 2 :-

= x

= 43°

Angle 3 :-

= x + 8

= 43 + 8

= 51°

[tex]therefore \: , \: the \: value \: of \: x = 43°[/tex]
