Answer:
x = 20
Step-by-step explanation:
since the triangle is a right angle, that means the angle is 90 degrees
equation:
30 + 3x = 90
subtract 30 on both sides
30 - 30 + 3x = 90 - 30
3x = 60
then divide each side by 3

x = 20

Step-by-step explanation:
Have a great day
This is a linear equation or y=mx+c. Where y is the number of mosquitos at a particular month and x is the number of months. We know the initial population of the mosquitoes is c=20. They population doubles every month so this is the gradient, m=2. Therefore the equation for the growth of the mosquito population is:
y = 2x + 20.
So after x= 10 months the mosquito population will be,
y=2(10)+20= 40.
There will be 40 mosquitoes after ten months.
Answer:
_6x-y=11/ 6x+y+11=0 this is the answer
