Answer:
One side of the park is 63 feet.
C is the correct option.
Step-by-step explanation:
We have been given that the shape of the city park is a square and the area if the park is 441 square yards.We have to find the side of the park.
We know that the four sides of a square is equal and the area is given by
On substituting the value of area, we get
Take square root both sides and ignore the negative values of side
On simplifying, we get
Side = 21 yards
Now, we know that
1 yard = 3 feet
Hence, we have
21 yards = 3×21 = 63 feet
Therefore, one side of the park is 63 feet.
C is the correct option.
15x+25y=1875
Let
y=95-x
15x+25 (95-x)=1875
Solve for x
15x+2375-25x=1875
15x-25x=1875-2375
-10x=-500
X=500/10
X=50 the number of $15 items
Y=95-50=45 the number of $25 items
9514 1404 393
Answer:
3
Step-by-step explanation:
Let x represent the number. The problem statement tells you ...
2/3(3x +6) = 10
2x +4 = 10 . . . . . . use the distributive property
x +2 = 5 . . . . . . . . divide by 2
x = 3 . . . . . . . . . . .subtract 3
The number is 3.

<em>Comment on the solution</em>
The above shows an "alternative" solution method. The more usual way this might be done is ...
2(3x +6) = 30 . . . . . multiply by 3 to clear fractions
6x +12 = 30 . . . . . . . eliminate parentheses
6x = 18 . . . . . . . . . . . subtract 12
x = 3 . . . . . . . . . . . . divide by 6
What’s standard form again? I forgot
