You spent $175 on a pair of shoes and three shirts. Each shirt cost the same amount. The shoes cost four times the amount of one
sergey [27]

Step-by-step explanation:

1. making the equation:

shoes = x

shirts = y

175 = x + 3y

x = 4y

2. graph it (I'm using desmos)

the green line is for 175 = x + 3y and the purple one is for x = 4y

3. find the price

x = 4y

175 = 4y + 3y

175 = 7y

y = 175/7 = $25

price of the shirt = $25

x = 4y = 4*25 = $100

price of a pair of shoes = $100

Michael reads 12 pages of a book in 18 minutes, 8 pages in 12 minutes, and 20 pages in 30 minutes. I’d this a proportional relat
Alex73 [517]

Answer:

Y= 1.5x

Step-by-step explanation:

What you would do is divide all of the minutes by the amount of pages to find how long for each rate for one page. (ex. 18/12, Michael reads 1 page in 1.5 minutes. 12/8, Michael reads 1 page in 1.5 minutes. 30/20, Michael reads one page in 1.5 minutes) Therefore, yes it is proportional, and the equation is y=1.5x (there is no y intercept)

I hope this will help

.<br> How do we write simple expressions using long &amp; synthetic division?<br><br> Explain
igomit [66]

Answer:

For not exact divisions: Writing the results as Quotient + Remainder over the Divisor.

For exact division: just the quotient.

Step-by-step explanation:

Hi there,

In both algorithms, for long and synthetic divisions we must write the result as an expression following that order:

Dividend: Divisor=Qx+\frac{Rx}{Dx}

When the Division leaves no Remainder, i.e. an exact, the Remainder is equal to zero, so

Dividend: Divisor=Qx

Check below for the algorithms for each division and the way of writing their expressions (results).

P(x) = 3x + 4<br>q(x) = 2x2<br>Find q(P(x))​
max2010maxim [7]

Answer:

Step-by-step explanation:

If we are to find q(p(x)), we are to start at the innermost part of the problem which is p(x). Take the function p(x) and fill it into q(x) every place you see an x:

2(3x+4)^2 is the composition of p into q.  Now all we have left to do is simplify.

(3x+4)^2=9x^2+24x+16

Then we have to finally multiply in the 2 to get:

18x^2+48x+32

Simplify the expression<br> -2/3(12c - 9) + 14c
postnew [5]
Greetings!

Simplify the Expression.
=\frac{-2}{3}(12c-9)+14c

Distribute the Parenthesis.
<em>How?</em> <span>Multiply the terms inside the Parenthesis by the term outside of the Parenthesis.
</span>=\frac{-2}{3}*12c-\frac{-2}{3}*9+14c

=\frac{-2}{3}*\frac{12}{1}c-\frac{-2}{3}*\frac{9}{1}+14c


=\frac{-24}{3}c-\frac{-18}{3}+14c

Combine Like Terms.
=\frac{-24}{3}c+\frac{14}{1}c-\frac{-18}{3}

=\frac{18}{3}c-\frac{-18}{3}

Reduce to Lowest Terms.
=6c-6

The Answer Is:
\left[\begin{array}{ccc}=6c-6\end{array}\right]

Hope this helps.
