Answer: Hope this helps <3
Step-by-step explanation:
To solve just isolate y from 2x-y=-1 to get y=2x+1. Then substitute y=2x+1 into 3x-2y=1. So it should be this: 3x-2(2x+1)=1. Distribute to get 3x+4x-2=1. Add the x's to get 7x-2=1, add two to both sides to get 7x=3 and divide to finally get x=3/7.

Step-by-step explanation:
Answer:
The answer would be 35
Step-by-step explanation:
To solve correctly, we would need to follow PEMDAS
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction
The first thing we see in this equation is Exponents, so we would fill in 3 for X, and so -3^2 is 9.
The next thing in the equation is Multiplication, so the next thing in the equation we would do is -4 times -11, which is 44.
The final thing in the equation is Addition, so we would add -9 add 44, which the answer would be 35.
Hope this helps!
Answer:
<u>42.25π m²</u>
Step-by-step explanation:
Let's solve!
⇒ Take the radius of the lawn to be 'r'
===========================================================
Then, area of the path equals :
⇒ Area of (lawn + path) - Area of lawn
⇒ π (r + 2)² - πr² = 30π
⇒ πr² - πr² + 4πr + 4π = 30π
⇒ 4πr = 26π
⇒ r = 6.5 m
===========================================================
Area of the lawn :
⇒ Area = πr²
⇒ Area = π × (6.5)²
⇒ Area = <u>42.25π m²</u>
