I need help. I don't understand this question.
Sergeu [11.5K]

Answer:

p=25

Step-by-step explanation:

-5[-9=-\frac{p}{5} -4]    Get rid of the fraction by multiplying the whole equation by -5.

45=p+20      Then, subtract 20 from both sides.

25=p

-Help me with this math graph I’ll give a lot of points for correct answer and work <br> *brainlist*
loris [4]

Check the picture below.

the constant of proportionality, namely the slope, for the original rectangle will just be 4/2 = 2, and for the dilated version shown that he did, it'll be 20/10 = 2.

part B)

we know the slope is 2, or 2/1 so then

\bf \cfrac{length}{width}\implies \stackrel{\stackrel{slope}{\downarrow }}{\cfrac{rise}{run}}\implies \cfrac{2}{1}~\hspace{2.7em}\stackrel{\textit{using a rectangle with a lenght of 14~\hfill }}{\cfrac{14}{w}=\cfrac{2}{1}\implies 14=2w\implies \cfrac{14}{2}=w\implies 7=w}

A group of friends wants to go to the amusement park. They have no more than $275
Zanzabum

Answer:

10 persons

Step-by-step explanation:

Step one:

given data

We are told that they have a total of $275

also, they want to spend $5 on packing space

and a ticket cost $27 per person.

Step two:

let the number of persons be x

and let the total amount to be spent be y

hence the inequality is

y≤ 5+ 27x

now for y= $275, let us find x

Substitute into the inequality we have

275≤5+27x

275-5≤27x

270≤27x

Divide both sides by 27

x ≤ 270/27

x ≤ 10

Hence the number of persons should not be more than 10

Simplify -3d^-8(-4d^-14)
Brut [27]

Answer:

\large\boxed{12d^{-22}=\dfrac{12}{d^{22}}}

Step-by-step explanation:

(-3d^{-8})(-4d^{-14})=\bigg((-3)(-4)\bigg)\bigg((d^{-8})(d^{-14})\bigg)\\\\\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=12d^{-8+(-14)}=12d^{-22}

\text{You can use}\ a^{-n}=\dfrac{1}{a^n}\\\\12d^{-22}=12\cdot\dfrac{1}{d^{22}}=\dfrac{12}{d^{22}}
