I believe your answer is:
"Add 4 to both sides, and then divide by 2. The solution is x = 12."

Here’s why:
⸻⸻⸻⸻
- To solve for 'x', we would have to use inverse operations.
- We would first have to add four to both sides to undo the negative four. Addition is the opposite of subtraction.
- We would then divide by 2 to isolate 'x'. Division is the opposite of multiplication.

Hope this helps you. I apologize if it’s incorrect.
Answer:
-4.5
Step-by-step explanation:
Basically, you're solving a proportion.
the proportion would be:
40/100 = 10/x
40 goes over 100 since it's a percent, and 10 and 40% are equal since 10 of the students in the art class represent 40% of the total number of students. X represents the missing info, which is the total number of students.
Now, you just cross multiply:
40(x) = 40x
10(100) = 1000
Since that's done, you now divide 1000 by 40, which equals 25.
There are 25 students in the art class :)
Answer:
basic geometry and trig ratios
Step-by-step explanation:
sin 10 = 500/x
x = 500/sin 10
x = 2 879,4 m
