192 people were survey

Step-by-step explanation:

The given is:

85% of the people survey thought the price of the car wash was reasonable
164 people thought the cost of the car wash was reasonable

We need to find how many people were survey

Assume that x people were survey

∵ There were x people survey

∵ 85% of them thought the price of the car wash was reasonable

∴ The number of the people who thought the price of the car wash

was reasonable = 85% × x

∵ 85% = $\frac{85}{100}$ = 0.85

∴ The number of the people who thought the price of the car wash

was reasonable = 0.85 x

∵ 164 people thought the cost of the car wash was reasonable

- Equate 0.85 x and 164

∴ 0.85 x = 164

- Divide both sides by 0.85

∴ x = 192.94

∵ x represents a number of people, then it must be integer

∴ The number of people were survey = 192

192 people were survey

Please help me in math

Marta_Voda [28]

When we have negative exponents, we can move the term with the exponent to the bottom of the fraction. This is also known as multiplying by the reciprocal (and changing the negative exponent to be positive!).

The reciprocal of z^-3 would be 1 / z^3.

Hope this helps!! :)

Answer:

price for one shirt

7.50

price for one pair of pants

18.50

Explanation:

Start by letting variables

and

represent the pieces of clothing from the problem.

Let

be the price of one shirt.

Let

be the price of one pair of pants.

Equation

85.50

Equation

115.00

You can solve for each variable by using elimination or substitution. However, in this case, we will use use elimination. First, we will solve for

, the price of each pair of pants.

To isolate for

, we must eliminate

. We can do this by making the two equations have the same

values. First, we find the LCM of

and

, which is

. Next, multiply equation

and equation

so that

and

becomes

in both equations.

Equation

85.50

(

)

(

85.50

)

256.50

Equation

115.00

(

)

(

115.00

)

460.00

Now that we have two equations with

, we can subtract equation

from equation

to solve for

256.50

460.00

−

203.50

18.50

⇒

price for one pair of pants

Now that we know that a pair of pants is

18.50

, we can substitute this value into either equation

to find price for one shirt. In this case, we will choose equation

85.50

(

18.50

)

85.50

55.5

85.50

7.50

⇒

price for one shirt

∴

, the price for one shirt is

7.50

and the price for one pair of pants is

18.50

Which angles are a linear pair

mihalych1998 [28]

Two angles are said to be linear if they are adjacent angles formed by two intersecting lines. The measure of a straight angle is 180 degrees, so a linear pair of angles must add up to 180 degrees.
