Answer:

1.) 15-3-2=x

2.) He can buy 3 sodas

Step-by-step explanation:

1.) 15 is how much he has, -3 is the price of the popcorn, -2is the price of the soda. =x is what needs to be solved in the equation (its 10 if you need the answer)

2.) He can buy 3 sodas because 3 boxes of popcorn is $9 since one box is $3,  he has $15 you take away $9 and you are left with $6 and 6 divided by 2 is 3.

Answer:

All of the above.

Step-by-step explanation:

In a graph, the unit rate gives us the change in y for a unit change in x. That is, the unit rate is the rate of change in y when the change in x is 1.

Therefore, the unit rate is the same as the rate of change.

And the rate of change is synonymous with the slope.

The constant of proportionality is simply the slope/rate of change for proportional equations.

Therefore, the constant of proportionality is also another word for the unit rate.

Our answer is hence all of the above.

Step-by-step explanation:

[tex]3x - 4(2x - 5) = \\ 3x - 8x + 20 = \\ - 5x + 20 = \\ 20 - 5x = > \: true[/tex]

Answer:

true

Step-by-step explanation:

3x -4(2x-5)

3x-8x+20

5x+20

If the sum of 5 and x is 20, then the value of x will be 15.

It is given that the sum of 5 and x is 20.

Mathematically, it can be written as:

5 + x = 20

We have to find the value of x.

In order to find the value of x we need to separate the variable and constant.

For this, subtract 5 from both the sides:

5+x-5 = 20-5

5-5 +x = 20-5

Then, solve the operation of subtraction on both the sides of above equation.

0+x = 15   -------(A)

Since, when we add 0 to any quantity, the result will be this quantity itself.

So, 0+x = x -------(B)

From (A) and (B), Sine the left sides of equation (A) and (B) are equal, then the right sides will also be equal.

Equation right sides of (A) and (B). We have:

x = 15

Hence, the value of x is 15.

Answer:

-1.8x² - 1.61x - 37.45 > 0

Step-by-step explanation:

Pattie's Produce charges $2.29 for a package of strawberries. On average, Pattie's Produce sells 95 packages of strawberries daily. They estimate that for each 20-cent increase in the cost of a package of strawberries, 9 less packages will be sold each day. Let x represent the number of 20-cent increases in the cost of a package of strawberries. Which inequality represents the values of x that would allow Pattie's Produce to have a daily revenue of at least $255 from selling the packages of strawberries?

Answer:

The cost of packaging 95 packages of strawberries is $2.29(95)=$217.55.

20-cent increase in the cost of a package of strawberries leads to 9 less packages to be sold. If x represent the number of 20-cent increases in the cost of a package of strawberries. the cost of packaging is:

Cost = (2.29 + 0.2x)(95 - 9x)

For a revenue of atleast $255:

(2.29 + 0.2x)(95 - 9x) > 255

217.55 - 20.61x + 19x - 1.8x² > 255

-1.8x² - 1.61x + 217.55 > 255

-1.8x² - 1.61x + 217.55 - 255 > 0

-1.8x² - 1.61x - 37.45 > 0

The value of x in the proportion below is option 1 3 1/2.

When using the butterfly method approach, the denominator of the first term is multiplied by the numerator of the second term, and vice versa.

An equation known as proportion shows that the two ratios presented are equal to one another. In other terms, the proportion declares that the two ratios or fractions are equal. In terms of proportion, two sets of supplied numbers are said to be directly proportional if they increase or decrease in the same ratio.

The given proportion is:

[tex]\frac{\frac{1}{2} }{4} = \frac{x}{28}[/tex]

Using the method of cross-product or butterfly method:

[tex]\frac{\frac{1}{2} (28) }{4}=x \\\\\frac{14}{4}=x\\ \\x=3.5[/tex]

The value of x is 3.5. Converting this value into mixed fraction:

3.5 = 3 1/2

Hence, the value of x in the proportion below is option 1 3 1/2.

Answer:

x-(-0.9)

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation::3*x+7*x-(9-18)=0

Solve::10x+9 = 0

Subtract 9 from both sides of the equation::10x = -9

Divide both sides of the equation by 10::x = -9/10 = -0.900

Answer:

Step-by-step explanation:

3x+7x=9-18

10x = -9

x = -9 / 10

x = -0.9

Answer:

Step-by-step explanation:

A fucntion is basically a machine that follows the instructions it's given and based on those instructions it gives you an answer. So in the function

f(x)=-x+7, our total output (answer) is going to be whatever our "x" is and adding that to 7.

So lets start with -2, plug in -2 for the x variable

f(x)=-(-2)+7, when we solve this we get f(x)=2+7 (negative*negative=positive)

so our final function would be f(x)=9

We can solve the other functions by plugging in the x variable in the same way:  

f(x)=-(-1)+7  this simplifies to f(x)=1+7, so f(x) equals 8

f(x)=-(0)+7   this simplifies to f(x)=0+7, so f(x)=7

f(x)=-(1)+7  this simplifies to f(x)=-1+7, so f(x)=6

f(x)=-(2)+7 this simplifies to f(x)=-2+7, so f(x)=5

Answer: 5^3 / 5^-3 = 5^6 = 15,625

Step-by-step explanation:

Ok, you may find useful for problems like this the next two relations:

[tex]x^a*x^b = x^{a + b}[/tex]

[tex]x^a/x^b = x^{a - b}[/tex]

Now we have the equation:

5^3/5^-3

We have a quotient, then we need to use the second relationship, where:

x = 5

a = 3

b = -3

5^3/5^-3 = 5^(3 - (-3)) = 5^(3 + 3) = 5^6 = 15,625

Answer:

384

Step-by-step explanation:

No. of students in the club last year = 320

No. of students in the club this year increased by 20%

To find the actual increase, 20% is multiplied by the number of students in the club last year which is 320 and to find the number of students in the club this year add the answer to 320 (the number of students in the club last year)

That is,

= 20% * 320

= 20/100 * 320

= 64

Finding the number of students in the club this year

320 + 64 = 384 students

NOTE : Increase means addition that is why the number of students in the club last year is added to the actual increase
