Answer:image
Step-by-step explanation:The photo is the answer
We can find the diameter of the circle by replacing some values in the formula for circumference. The formula for find the circumference is pi * d, where pi could equal 3.14 or 22/7 and d is the diameter. After dividing pi from both sides (I used 3.14), we have the total of about 21.01, which would be our diameter. We add 4 more feet into it, resulting in 25.01 feet, and we just multiply that by $0.45 to get the total price.
We get around $11.25 as our total price.
Answer:
3x+17
Step-by-step explanation:
2(2x+6) - x + 5--->distibutive property
(4x + 12) -x + 5
3x + 17, you were correct
Answer:
(2, - 3)
Step-by-step explanation:
given the 2 equations
5x + 3y = 1 → (1)
7x + 3y = 5 → (2)
multiply all terms in (1) by - 1
- 5x - 3y = - 1 → (3)
add (2) and (3) term by term to eliminate the term in y
(7x - 5x) + (3y - 3y) = (5 - 1)
2x = 4 ( divide both sides by 2 )
x = 2
Substitute x = 2 in either (1) or (2) for corresponding value of y
(2) : 14 + 3y = 5 ( subtract 14 from both sides )
3y = - 9 ( divide both sides by 3 )
y = - 3
solution is (2, - 3)
