Answer:
no
Step-by-step explanation:
its is not a solution, however if the equal sign actually looks like
then it would be yes
For big circle the diameter is 10 so the radius is 5. Use the equation for the area of a circle pi r^2.
Pi is 3.14 as said in the question.
So 3.14 x 5^2 or 25 x 3.14=78.5
For smaller circle, diameter is 6cm so the radius is 3.
Using the same area of a circle equation it would equal 3.14 x 3^2 or 9 x 3.14=28.26
Take 28.26 away from 78.5 to get 50.24.
To the nearest tenth would mean it would equal 50.2
The last option is the answer
It's just adding not multiplying. it would just be 5y+3
Answer:
Both zero
Step-by-step explanation:
Adding both eqs
2x+6y-2x-5y=0+0
y=0
Putting in first equation
2x=0
x=0
Answer:
-48/11
Step-by-step explanation:
-2x+5-40-9x-13=0
-11x=40-5+13
-11x=48
x=-48/11
