Answer: -2 and -3

Step-by-step explanation:

Answers: lol sorry very long answer

part a answer: Yes, because if we substitute the variables, the equation will be 15(6) + 10(21) = 300. Simplifying this will be 90 + 210 = 300. And since 90 + 210 does equal 300, 21 students and 6 adults can go to the zoo

part b answer: 24 students. Using the equation 15x + 10y = 300, we can find out the maximum number of students who can go to the zoo. First we can substitute x for 4 because that's how many adults who need the tickets. The equation will now be 15(4) + 10y = 300. Simplifying this will be 60 + 10y = 300. Now we can subtract 60 on both sides to isolate the y term. The equation will be 10y = 240. Divide each side by 10 to find out what y is and we get y = 24. So if 4 adults go the zoo, up to 24 students can go.

part c answer: y = 30 - 1.5x. To solve 15x + 10y =300, we first need to move 15x to one side of the equation. To do this we will subtract it on both sides. The equation is now 10y = 300 -15x. Then you will divide 10 on both sides to find out what y is. y = 30 - 1.5x.

Answer:

-60x + 32 = -60x - 32

Step-by-step explanation:

The first step to solve this question is combining the like terms in each option.

In those that we end up with:

0x = c

In which c != 0, we have no solution. So

-60x + 32 = 32x + 60

-60x - 32x = 60 - 32

-92x = 28

No 0x, so it has solution

-60x + 32 = 32x - 60

-60x - 32x = -60 - 32

-92x = -92

No 0x, so it has solution

-60x + 32 = -60x - 32

-60x + 60x = -32 - 32

0x = -64

0x equaling a value different of 0, so no solution.

-60x + 32 = -60x + 60

Answer: If you want the result as a fraction it should be 3.7/5. but if you want a whole number it's 4.2. if you want a mixed number its 4 1/5

Step-by-step explanation:

The sequence that shows the numbers in order from least to greatest is A. |-8.23| < 8 1/5 < 8.3

It's important to note that arranging numbers from the least to the greatest simply means ascending order.

In this case, it's vital to note that the negative value is the smallest. Then 8 1/5 is 8.2. This conea after. The greatest number is 8.3 since it's the biggest.

In linear equation, The price at which the quantity demanded equals the quantity supplied is $ 260."  option (b) is answer.

What in mathematics is a linear equation?

a.  The demand for a product is given by p+3q= 315 or, q = (315 - p)/3 and the supply for this product is given by  p-7q = 65 or, q = (p- 65)/7

The price at which the quantity demanded equals the quantity supplied is given by

              315 - p/3 = p - 65/7

         7( 315 - p ) = 3( p - 65 )

        2405 - 7p = 3p - 195

        2405 + 195 = 3p + 7p

           2600 =  10p

Answer:

b > 6, b < -6

Step-by-step explanation:

Hello!

Using absolute value rules:

The compound inequality is as follows: b > 6, b < -6

This makes sense because all values turn positive in the asbolute value. So a number that is negative and less than -6 (say -7), would turn positive to be 7, which is greater than 6.

And any number already greater than 6 will always be greater than 6.

Step-by-step explanation:

The equation in slope intercept form is C(h) = 50h+25  ,the total cost for 8 hours of work is $425 , and for 10 hours of work  is  $525.

In the question;

it is given that

the fixed charge of plumber = $25

charge for per hour of service = $50

the hours of service be "h"

and the total cost be "C"

according to the question

C(h) = 50h+25

the equation in the slope intercept form is C(h) = 50h+25

to find the total cost for 8 hours of work , put h=8

C(8) = 50(8) + 25

= 400+25

= 425

to find the total cost for 10 hours of work , put h=10

C(10) = 50(10) + 25

= 500+25

= 525

Therefore , total cost for 8 hours of work is $425 , and for 10 hours of work  is $525 .

The given question is incomplete , the complete question is

Step-by-step explanation:

y varies INVERSELY as x.

that means

y = k/x

therefore,

22 = k/6

k = 22×6 = 132

and then, when y = 15

15 = 132/x

15x = 132

x = 132/15 = 8.8

2(x -2) = 50 is also true for the same value of x.

Given,

Part 1:

When a cardboard box is empty, its weight is 0.6 pounds.

It is filled with 15 bags of beans and a 4-pound bag of rice.

The total weight of the box and the contents inside it is 25.6 pounds.

Let the weight of 15 bean bags is 15b. The given scenario can be represented by the equation as follows :

0.6+15b+4=25.6 ....(A)

Taking like terms together,

15b=25.6-0.6-4 ...(1)

15b = 21  ....(2)

Equation (1) or (2) can be the equivalent equation for the equation (A).

Part 2:

Solve the equation:

7.5d = 2.5d, Lin divides each side by 2.5d,

and Elena subtracts 2.5d from each side.

Now, 7.5d/2.5d = 2.5d/2.5d

3 = 1

It is not equal, There is no solution.

a. 7.5d - 2.5d = 2.5d - 2.5d

5d/5 = 0/5

b. What is the solution ?

Solution is d = 0

Part 3:

Given,
The equation 4(x - 2) = 100  is a true equation for a particular value of x.

Explanation: The basic property of the equation is that if you multiply or divide both sides of the equation by the non-zero whole , the equation still holds.

In the Equation : 4 (x - 2) =100 divide by 2 on both sides because 2 is common factor of (4,10)

So, 4(x - 2) =100

1/2 x 4(x-2) = 1/2 x 100

= 2(x-2) = 50

Above all, 2(x -2) = 50 is also true for the same value of x.

Hence, 2(x -2) = 50 is also true for the same value of x.

Distances Sandra recorded in order from least to greatest is 1/9, 5/18, 11/36, 7/18, 17/36, 2/3.

Given that, the fractions represent the distances that Sandra recorded is 7/18, 2/3, 1/9, 11/36, 5/18, 17/36.

In Mathematics, fractions are represented as a numerical value, which defines a part of a whole. A fraction can be a portion or section of any quantity out of a whole, where the whole can be any number, a specific value, or a thing.

Here, distance is 10/36

So, the equivalent fractions for the given fractions are

7/18 = 14/36

2/3 = 24/36

1/9 = 4/36

11/36

5/18 = 10/36

17/36

So, least to greatest is

4/36 < 10/36 < 11/36 < 14/36 < 17/36 < 24/36

1/9 < 5/18 <11/36 <7/18 <17/36 <2/3

The diagonals of a rectangle are congruent, so RT = SU, that is

3x + 8 = 6x - 4

Subtract 8 from both sides 3x + 8 - 8 = 6x - 4 - 8

Simplifying the above equation, we get

3x = 6x-12

Subtract 6x from both sides 3x - 6x = 6x - 12 - 6x

The mean and standard deviation of the vehicle speed are 58.33 and 11.64 respectively.

The vehicle speed on a particular bridge in china has normal distribution.

5% represents the 5th percentile which is here, 39.18 m/h.

Since 10% travels more than 73.27 m/h, 90% travels less than 73.27 m/h.

So here the 90th percentile is 73.27 m/h.

Also the z-score, z = (x-μ)/σ, where μ is the mean of normal distribution and σ, the standard deviation.

So 39.18 corresponds to the z with p-value 0.05, i.e., z = -1.645 [from the normal tables]

Hence, z = (x-μ)/σ

⇒ -1.645 = (39.18 - μ)/σ

⇒ -1.645σ = 39.18 - μ

⇒ μ = 39.18 + 1.645σ  ----------(1)

Also 73.27 corresponds  to the z with p-value 0.9,i.e., z = 1.28.

Hence , z = (x-μ)/σ

⇒ 1.28 = (73.27 - μ)/σ

⇒ 1.28σ = 73.27 - μ

⇒ μ = 73.27 - 1.28σ  ----------(2)

Equating (1) and (2), we get,

39.18 + 1.645σ  =  73.27 - 1.28σ

2.925σ = 34.05
