So first convert 2 3/4 to improper fraction
2 3/4=8/4+3/4=11/4
11/4a=19 1/4
convert 19 1/4 to improper
19 1/4=76/4+1/4=77/4
11/4a=77/4
multiply both sdie sby 4
11a=77
divide by 11
a=7

Answer:
Bushes are $9.
Bonsai trees are $32.
Step-by-step explanation:
Bushes are b and bonsai trees are t.
15b + 8t = $391
9b + 5t = $241
15b + 8t = $391 × 3 and 9b + 5t = $241 × 5
= 45b + 24t = $1173 and 45b + 25t = $1205
(45b + 24t = $1173) - (45b + 25t = $1205)
t = 1205 - 1173
t = $32
Apply to 15b + 8t = $391.
15b + 32 × 8 = $391
15b = $391 = 32 × 8
15b = $391 - 256
15b = $135
x = ($135 ÷ 15) = $9
Answer:
D
Step-by-step explanation:
You don't need any real math to guess at the right answer.
Choice A requires at least 33+32+32=97 feet of fence, hence you an rule it out because that is more fence than you have.
Choice B requires at least 16+16+16=48 feet, hence you can rule it out because it does not use all your fence and you can get more area by using it all.
Choice C requires at least 48+16+16=80 feet of fence, which is more than you have.
Choice D requires at least 32+16+16=64 feet of fence, so this is the right choice.
