I don't understand how to do this, can someone please help me?
denis23 [38]

Answer:

x=1

Step-by-step explanation:

First find a common denominator between 7 and 4 which is 28, Multiply both equations by 28 eliminating the denominators so now you have theses two equations: 4(2x + 12) = 7(3x + 5) distribute these equations to get:

8x + 48 = 21x +35 now you want to get the x's on one side so 8-21 = -13 which as an equation so far would be -13x + 48 = 35 now do 35-48 = -13 so you can have 13x alone on one side. Your final equation now before you solve is

-13x = -13 the divide -13 by -13 to get 1.

Hope this helps you understand it better

The relative frequency for the class with lower class limit 31 is 8.57%.

<h3>How to calculate the frequency?</h3>

It should be noted that the lowrr class frequency is 31 in this case.

Therefore, the relative frequency for the class with lower class limit 31 will be:

= 3/(6+4+4+9+3+9) × 100

= 3/35 × 100

= 8.57%

Therefore, the relative frequency for the class with lower class limit 31 is 8.57%.
