Answer:
2+n = 8
Step-by-step explanation:
2+ something must equal 8.
8 minus 2 = 6
n=6
The system of equations that can be used to determine the number of small tables and the number of large tables the designer will make is:
y -x = 8
$12y - $6x = $236
<h3>Defining the variables </h3>
Let:
x = number of large tables the designer can make.
x = number of small tables the designer can make.
<h3>Simultaneous equations</h3>
Simultaneous equations are sets of equations that must be solved together in order to determine the required variables. Methods of solving simultaneous equations include:
- Elimination method
- substitution method
- Graph method

Answer:
Step-by-step explanation:
<u>Use cosine:</u>
- cos = adjacent / hypotenuse
- cos ∠L = KL/JL
- cos 21° = 4/x
- x = 4 / cos 21°
- x = 4.3 (rounded)
Answer:
The answer instead is 10:14.
Step-by-step explanation:
In this case, there are ten boys and fourteen girls in this class. The ration would then be 10:14. Instead, Jeff said 5:12 which isn't correct. He can correct it by using the number of boys given, find the difference of girls in a class of twenty-four students, and then get his answer!
