Find the value of x that makes line m parallel to line n.​
evablogger [386]

Answer: <em>x</em> = 20

Step-by-step explanation:

   If line <em>m</em> is parallel to line <em>n</em>, the two angles given will be congruent because they will be alternate exterior angles (which are congruent).

  This means we will set them equal to each other and solve for <em>x</em>.

Given:

(4<em>x</em> - 23) = (2<em>x</em> + 17)

Add 23 to both sides of the equation:

4<em>x</em> = 2<em>x</em> + 40

Subtract 2<em>x</em> from both sides of the equation:

2<em>x</em> = 40

Divide both sides of the equation by 2:

<em>x</em> = 20

Three girls download a total of 36 songs on their iPods. Jane downloaded twice as many as Inez and since Tracy wanted to have th
lesya692 [45]
J + i + t = 36
j = 2i
t = j + 1.....t = 2i + 1

(2i + 1) + i + (2i) = 36
5i + 1 = 36
5i = 36 - 1
5i = 35
i = 35/5
i = 7 <=== Inez downloaded 7 songs

j = 2i = 2(7) = 14 <==Jane downloaded 14 songs
t = 2i + 1 = 2(7) + 1 = 15 <== Tracy downloaded 15 songs

A recipe says to use 3cups of flour to make 48 cookies. What is a constant of proportionality that related the number of cookies
MA_775_DIABLO [31]

Answer:

y=16 x=1

Step-by-step explanation:

For this one, we need to find the unit rate, which means how many cookies we can make using 1 cup of flour. To do that, we need to divide both the flour and the cookies by 3 to get 3/3=1 and 48/3=16. So the total amount of cookies made with one cup of flour is 16. So the constant proportionality is 16,1.
