Would be the value of x
gladu [14]

Answer:

for the perimeter to be made into a equation it would take the equation

2(3x - 5) + 2(2x + 1)

And for the perimeter to equal 42 x would have to equal 5

Step-by-step explanation:

so first of all we have to find our equation to equal 42:

2(3x - 5) + 2(2x + 1) = 42

you then multiply 2 for both parentheses:

(3x * 2) + (-5 * 2) + (2x * 2) + (1 * 2) = 42

so its now:

6x -10 + 4x + 2 = 42

now your going to add variables to variables and numbers to numbers:

(6x + 4x) + ( -10 + 2) = 42

to get:

10x + (-8) = 42

Now your going to add 8 to both sides:

10x + (-8) = 42

         +8    +8

Giving the equation:

10x = 50

now you divide both sides by 10 to get:

10x/ 10 = 50/10

x = 5

to solve you put 5 in place of the variable x:

2(3*5 - 5) + 2(2*5 + 1)

2(15 - 5) + 2(10 + 1)

20 + 22 = 42

So x equals 5 if the perimeter equaled 42

Christina wants to buy some miniature goldfish. She reads that a 9-gallon aquarium is the
Ronch [10]

Based on the image attached of the graph, the points that show equivalent ratios that would also be on the graph are option A and D which are: (6,18)  (1,3).

<h3>What is the graph about?</h3>

Note that: \frac{x}{y}

=\frac{3}{9}

= 1/3

So when you use 1/3 to compare all the options given, you will see that only option A and D  is equal to the value given.

So if a person can write that  we got  1 fish and we needs 3 gallons and when a person  make a point on the line, it will be (1,3).

The other equivalent fraction is known to be 6/18. When a person multiply the numerator and denominator by 2, the value that will be obtained is:

\frac{3 x 2 }{9 x 2}   = 6/18.

So therefore, Based on the image attached of the graph, the points that show equivalent ratios that would also be on the graph are option A and D which are: (6,18)  (1,3).

See full question below

wolverine [178]
<span>Set the two equations equal to each other and solve for x
 10x +50 = 8x +60
          -50 -50
-----------------
10x = 8x + 10

 10x = 8x + 10
           -8x -8x
---------------
2x = 10 2x = 10

divide by 2 on both sides x=5 five additional services are needed for the two companies prices to be equal </span>
