Find the value of x given m (I need a lot of help)

Answer:

2.5 or 5/2

Step-by-step explanation:

2x-3=2

2x=5 (both sides plus 3)

x=5/2 or 2.5(divid by 2 on both sides)

Answer:

SI is used in most places around the world, so our use of it allows scientists from disparate regions to use a single standard in communicating scientific data without vocabulary confusion.

Answer:

40%

Step-by-step explanation:

Number of girls = 7

Number of boys = 13

Total students = 7 girls + 13 boys

= 20 students

Running club

Number of girls = 5

Number of boys = 3

Total students in the running club = 5 girls + 3 boys

= 8 students

percentage of the students that are in the Running club = Total students in the running club / Total students

× 100

= 8/20 × 100

= 0.4 × 100

= 40%

Percentage of the students

at this Private School are in the Running club is 40%

IM LEARNING THIS TOO LOL

angle one and angle 2 are congruent because of the corresponding angles theorem

angles 2 and 3 are linear pair so 1 plus 2 equals 180

i believe you can use the transitive property

Answer:

Constant

part

whole

Step-by-step explanation:

From the question, we want to fill in the gaps with the correct vocabulary

The correct wordings in this question is that;

A percent is a constant of proportionality describing the part of the whole

What we are trying to learn here is that a percentage of something is just a value that represents how big that particular value is to the entire whole value

Answer: The value of x= 270

Step-by-step explanation:

Given: Willy Wonka has x chocolate bars in his factory.

Chocolates he gave = [tex]\dfrac13 x[/tex]

Remaining chocolates =  [tex]x-\dfrac{x}{3}=\dfrac{2x}{3}[/tex]

Half of the remaining chocolate bars = [tex]\dfrac12\times\dfrac{2x}{3}=\dfrac{x}{3}[/tex]

Now , Chocolate left [tex]x-\dfrac{x}{3}-\dfrac{x}{3}=\dfrac{3x-2x}{3}=\dfrac{x}{3}[/tex]

As per given , [tex]\dfrac x3=90[/tex]

[tex]\Rightarrow\ x=90\times3=270[/tex]

Hence, the value of x= 270

Answer:

The values of a,b,c and d are as follows:

a = 3, b = -12, c = -5, d = 10

Step-by-step explanation:

Given functions are:

[tex]f(x) = 4x^3-12x^2+10\\g(x) = x^3-2x^2+5x[/tex]

We have to find the value of f(x) - g(x). This means we have to subtract function g(x) from function f(x)

So,

[tex]f(x) - g(x) = (4x^3-12x^2+10)-(x^3-2x^2+5x)\\= 4x^3-12x^2+10-x^3+2x^2-5x[/tex]

Combining alike terms

[tex]= 4x^3-x^3-12x^2+2x^2-5x+10\\= 3x^3-10x^2-5x+10[/tex]

Now it was given that:

f(x)- g(x)= ax^3+bx^2+ cx+d

By comparing both we get

a = 3, b = -12, c = -5, d = 10

Hence,

The values of a,b,c and d are as follows:

a = 3, b = -12, c = -5, d = 10

Answer:

personally i think c

Step-by-step explanation:

its because for the graph there is 90 and it has a point and when i used a calc i put the points and the a=18 so 90 eould be 18 again this what i think i am not really AMAZING at it but i get some of it for ex the chart equals it only equals a=5

Cost per metre = Rs. 5

Total cost = Rs. 2000

Then total length of the fence = Rs.2000/Rs.5

= 400 metre

Total length of the fence = 400 metre

Answer: [tex]\frac{6}{2}[/tex]

Step-by-step explanation:

1. Use this [tex]\frac{f(b)-f(a)}{b-a}[/tex] to find the average rate of change

2. Average rate of change = [tex]\frac{f(8)-f(6)}{8-6}[/tex]

3. [tex]f(8) = - 4[/tex] and [tex]f(6) = -10[/tex] (To find these you will need to look at the points on the graph. So the points (8,-4) and (6,-10))

4. Replace -4 to f(8) and -10 to f(6)

5. So it will look like[tex]\frac{-4-(-10)}{8-6}[/tex]

6. Solve [tex]\frac{6}{2}[/tex]

Answer:

C. 8

Step-by-step explanation:

8 x 40 = 320$ plus 30$ fee is 350

Answer:

5 trips

Step-by-step explanation:

6.48 km = 4 trips

1 trip = 6.48km ÷ 4 trips

1.62km = 1trip

8.1 kilometers ÷ 1 trip = 8.1 kilometers ÷ 1.62km

8.1 kilometers = 5 trips

∴ 8.1kilometers covers 5 trips

Answer:

g = -3

Step-by-step explanation:

subtract 6 on both sides

-2g = 6

divide by -2

g = -3

Answer:

G=-3

Step-by-step explanation:

I have used an online algebra calculator to check my answer against and I got the answer g= -3 both times so I am 100% positive that the answer is correct.

Answer:

[tex]y+3=\frac{2}{5} (x+5)[/tex]

Step-by-step explanation:

First, let's find the slope using the 2 given points and the slope equation.

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Enter in the points:

[tex]m=\frac{-3--1}{-5-0}[/tex]

Simplify:

[tex]m=\frac{-2}{-5}[/tex]

[tex]m=\frac{2}{5}[/tex]

Now that we have slope we can just use one of the points given. Remember point-slope form:

[tex]y-y1=m(x-x1)[/tex]

I'll use the point (-5,-3) in this case.

So, your solution is

[tex]y+3=\frac{2}{5} (x+5)[/tex]

Hope this helps!
