Alright, lets get started.

(A) The total length of backyard is = 8 + 9 = 17 ft

The total width of backyard is = 5 + 3 = 8 ft

Hence total area of backyard = length * width

Hence total area of backyard = 17 * 8 = 136 square feet

Now area of Patio = 5 * 8 = 40 square feet

Now area of walkway = 3 * 8 = 24 square feet

Now area of garden = 6 * 3 = 18 square feet

Total area of Patio, walkway and garden = 40 + 24 + 18

Total area of Patio, walkway and garden = 82 square feet

So, percent of the total area of Hal’s backyard is taken up by the patio, walkway, and garden = \frac{82}{136} * 100

percent will be = 60.3 %

Means 60 % : Answer (A)

(B) One longer side of Hal’s backyard lies next to the back of his house.

So, he not need to built fence on this side.

So, rest three sides he needs fencing.

The length of rest three sides will be = 17 + 8 + 8

length of three sides = 33 ft

For 1 feet, it takes = $ 9.75

So, for 33 ft, it take = 33*9.75 = 321.75

Hal spent $ 321.75 for his new fence. : Answer (B)


Hope it will help :)

4x - 5= 2(2x - 1) -3
Alekssandra [29.7K]

Answer and Step-by-step explanation:

Solve for x.

Distribute the 2.

4x - 5 = 4x - 2 - 3

Combine like terms

4x - 5 = 4x - 5

Add 5, and subtract 4x.

0 = 0

There are infinitely many solutions, meaning any value plugged in for x will result in the equation being true.

lozanna [386]
Okay so the equation. Lets say e is explorers and v is flying vs and m = money.

e + v > or = 30.

80e + 5v =m.
 
e < or = 20\
v < or = 20.
Okay, the most money he could make would be if he made 20 explorers at 80 dollars and 10 vs at 5 dollars.
Total money...
1600 + 50 = 1650.
So he could make $1650.
