Answer:
x = - 1
Step-by-step explanation:
- 5x - 16 = 9x + x - 1
- 5x - 16 + 16 = 9x + x - 1 + 16
- 5x = 9x + x - 1 + 16
- 5x = 10x + 15
- 5x - 10x = 10x - 10x + 15
- 15x = 10x - 10x + 15
- 15x = 15
- 15x ÷ - 15 = 15 ÷ - 15
x = 15 ÷ - 15
x = - 1
Answer :The population of a colony of mosquitoes obeys the law of uninhibited growth. If there are 1000 mosquitoes initially and there are 1400 after 1​ day
Step-by-step explanation:
Answer:
∠ACD= 109°
Step-by-step explanation:
∠A=38
180- ∠A= ∠B+C
180-38= 2∠B( ∠B=∠C) ( angles opposite to equal sides are equal)
142=2∠B
∠B=71
∠ACD=∠A+∠B ( exterior angle property)
∠ACD= 38+ 71= 109°
4x=x-1+19 -> 4x=x+18 (then you minus 1x from both sides) -> 3x=18; x=6
