Multiply the bracket by 5
10x+25= 4x-7
10x-4x+25= 4x-4x-7
6x+25= -7
6x+25-25= -7-25
6x= -32
Divide by 6 for 6x and -32
6x/6= -32/6
x= -32/6
divide by 2 for -32/6
x= -16/3
Answer is -16/3 ( improper fraction) or -5 1/3 ( mixed number)
Vertical angles are identical, so if X is 100 degrees, then Y is also 100 degrees.
half of 100 = 100 / 2 = 50 degrees.
Answer:
Step-by-step explanation:
1. 2a + 3a + 3 = 8
5a + 3 = 8
5a = 5
a = 1
2. 3a - 2a - 4 = 0
a - 4 = 0
a = 4
3. 4 + 3a + 6 = 16
3a + 10 = 16
3a = 6
a = 2
4. 12a - 6a + 6 = 24
6a + 6 = 24
6a = 18
a = 3
The answer is 12.64. I hope I helped. :)
