Answer:

4,24,48

Step-by-step explanation:

For the first equation, they are splitting 8 in half. So 8/2 would be 4. The 4 would go in the first box.

Then 4x6 is 24 in the second box.

Then just add 24 and 24. 24+24=48

And your last answer is 48.

Answer:

x = 19.6

Step-by-step explanation:

If we need to find the value of x then first we need to

(7x-25) + (3x +9) = 180  (angles at the same side of transversal will be equal to 180 degree )

10x -16 = 180

10x = 180 +16

10x = 196

x = 196/10

x = 19.6

Answer:

c³ + cd³ + 3c²d + 3cd²

Step-by-step explanation:

(c+d)^3 is worded as c plus d quantity cubed which doesn't mean you cube everything inside. It means you multiply the quantity by itself 3 times.

(c+d)(c+d)(c+d)

You can only multiply 2 at a time so do the first two then the result and the third one.

Distribute everything in one quantity to the other so c*c = c^2 and c*d = cd

= (c^2 + 2cd + d^2)(c+d)

= c^3 + c^2d + 2c^2d + 2cd^2 + cd^2 + cd^3

Combine like terms

= c³ + 3c²d + 3cd² + cd³

Answer:

The answer is A

Step-by-step explanation:

Midpoint formula:  (x1 + x2) / 2, (y1 + y2) / 2

In this case, we already have the midpoint, so one of the x and one of the y values are unknown, whereas the sum is not.

(-1 + x) / 2 = 5, (3 + y) / 2 = -2

For both equations multiply both sides by 2

-1 + x = 10, 3 + y = -4

x = 11, y = -7

Rewrite as coordinates.

(11, -7)

Step-by-step explanation:

75 beats for one minute times 10 mins

Answer:

x = -12.

Step-by-step explanation:

Number in the square next to  5 =  3+x.

Number to the right of this one = x + 1

From left to right the umbers in the second row = 5 + 3 + x

and 3 + x + x + 1

= x + 8 and 2x + 4.

So x + 8 + 2x + 4 = 2x

so 3x + 12 = 2x

x + 12 = 0

x = -12.

Answer: 7.5 (h)

Step-by-step explanation:

Let say

a the outflow of the first pipe

b the outflow of the second pipe

T the volume of the tank.

x the time for filling with the second pipe

two pipes can fill a tank in 3 hours: a*3+b*3=T

One pipe alone can fill the tank in 5 hours : a*5=T

3*b=T -3a ==> 3b= 5a*3a=2a

b=2a/3

b*x=T ==> 2/3*a*x=T ==> 2/3*T/5*x=T ==> 2/15*x=1

x=15/2 = 7.5 (hours)

Step-by-step explanation:

[tex]\boxed{\sf a_n=\dfrac{a_{n-1}}{10}\times 4,n\gt 1}[/tex]

Lets verify

[tex]\\ \sf\longmapsto a_2=\dfrac{a_1}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_2=\dfrac{500}{10}\times 4=50(4)=200[/tex]

And

[tex]\\ \sf\longmapsto a_3=\dfrac{a_2}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_3=\dfrac{200}{10}\times 4=20(4)=80[/tex]

And

[tex]\\ \sf\longmapsto a_4=\dfrac{a_3}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_4=\dfrac{80}{10}\times 4=8(4)=32[/tex]

Hence verified

Lets predict next term

[tex]\\ \sf\longmapsto a_5=\dfrac{a_4}{10}\times 4[/tex]

[tex]\\ \sf\longmapsto a_5=\dfrac{32}{10}\times 4=3.2\times 4=12.8[/tex]

Step-by-step explanation:

v(x) = y = -3/4x - 1/3

y + 1/3 = -3/4x

x = -4/3 × (y + 1/3)

you see ? we only need to show how we calculate x out of y (instead of the normal direction of y or of x).

and to follow naming standards we now simply switch x and y, so that the inverse function is indeed again a function of x

y = -4/3 × (x + 1/3) = -4x/3 - 4/9

Step-by-step explanation:

-9+15

15-9

+6

So after there you can construct a numberline showing that.

-9+15 can be written as 15-9

Answer:

C.

Step-by-step explanation:

An equation is an identity if the equation is always true regardless of what value you replace 'x' with.

This means we need to simplify the equations above to see which one will be true for any value of 'x'.

After simplifying equation C, we get -12-8x = -12-8x. Since both sides of the equation are the same, this equation will be true regardless of what value replaces x so this equation is an identity.

Answer:

d = 3

Step-by-step explanation:

(7d+3)/4 = 6

Multiply each side by 4

(7d+3)/4*4 = 6*4

(7d+3) = 24

Subtract 3 from each side

7d+3-3 = 24-3

7d = 21

Divide by 7

7d/7 = 21/7

d = 3

Answer:

the number doesnt represent an integer?

A. 3

B. 20.1

C. -10

D. 20/4​

Step-by-step explanation:

We call integers the “counting numbers, their negatives and zero”. I.e.  0,1,−1,2,−2,3,−3,.. etc.

non-integers means “everything except integers”. Which is not well-defined (i.e. nonsense). Why? Because nobody said what “everything” is.

Therefore, when somebody says “non-integer” he has to specify how he defines “everything”. In this case, our “everything” is probably “real numbers”.

Real numbers have an interesting definition concerning an abstract mathematical object called “field” . Let’s forget about that and let’s focus on a high school definition: Real numbers are probably all the numbers you know. They are those represented by a decimal and their negatives e.g.  345.232…  and  −243.13242240…  where there are “infinitely many” digits at the end. Note that  2.5  is also a real number. Integers are too. Basically, real numbers are the numbers used to measure distances and their negatives.

To summirize, your answer is the following:

“non integers” means everything except the integers, where everything is defined however we want. The most common definition of everything in this case is “real numbers” and therefore the most common interpretation of “non integers” is “reals which are not integers”.

Examples of “reals which are not integers”:  1.5,2.88,1.3333…  etc

the answer is

B. 20.1
