Using multiplication, we get 5.8 x 8.3= 48.14
Example: 2x+2y=8 and 3y+2x=6
Okay so u first want to put on of the equations into a y= form. So let's use 3y+2x=6. Subtract 2x from both sides. 3y=6-2x divide by 3. Y= 6-2/3x or y= -2/3x + 6. Now just plug this new equation in for Y since "y=" into the other equation.
2x + 2(-2/3x + 6) = 8.
Then you would distribute the 2 into the parenthesis and simplify to solve for x.
After you solve for x, plug x into one of the original equations to find y.
Answer:
12.62 m
Step-by-step explanation:
Area of a circle = πr²
Area = 125m²
Hence:
125m² = πr²
r² = 125m²/π
r = √125m²/π
Hence,
r =√ 39.788735773
r = 6.3078313051 m
Diameter = Radius × 2
Therefore, Diameter of one circle is
= 6.3078313051 m × 2
= 12.61566261m
Approximately = 12.62 m
Brother=b
b+9=11
b=2
2=1/5a
10=a
a=10
The answer is 10
Hope this helps :)
