Answer(s):
If you are asking for the equation, it's 9(x+4)=2
However, if you're asking for the value of x as well, it's -34/9
Step by Step:
1) First we must find the equation. In your question, the unknown number is x. Therefore we can know that "the sum of a number and 4" is (x+4). Since we are multiplying this sum by 9, we can put the 9 in front of this expression to multiply it--getting 9(x+4). And since we know it "is 2" we can say that 9(x+4)=2.
2) Now, we have to solve the equation, 9(x+4) = 2
3) We can start by distributing, 9x+36 = 2
4) Now let's move 36 to the right by subtracting from both sides, 9x = -34
5) To isolate x, let's divide both sides by 9, x = -34/9
6) Our fraction answer can't be simplified, so we get x = -34/9
Answer:
x = 15°
Step-by-step explanation:
(5x-15) + 75 + 3x = 180
8x + 60 = 180
8x = 120
x = 15°

Answer:
-3<n<=5
Step-by-step explanation:
This is because the coloured circle on the number line means that the number is less than or equal to 5
