Area(A)= lw
perimeter(P)= 2w+2l= 34in
length(l)= w+5
width(w)= w
1/2 P= 17= w+l
17= w+(w+5)
17= 2w+5
2w=12
w=6 in
l= w+5
l= 6+5
l=11 in
A= lw= (11)(6)= 66in²
Answer:
Area of rectangle is 66 in².
Answer:
Lindsay owns 12 books
Step-by-step explanation:
1/3x:Lindsay
x:Destiny
1/4x: Henry
1/3x+1/4x+x=57
4/12x+3/12x+x=57
7/12x+x=57
19/12x=57
x=57*12/19
x=36
1/3x=36/3
1/3x=12
Answer:
140
Step-by-step explanation:
X=price of one drink.
y=price of one soft pretzel
We can suggest this system or equations:
3x+3y=9
4x+2y=8.5
We can solve this system of equations by substitution method.
3x+3y=9
3x=9-3y
x=9/3 - 3/3 y
x=3-y
4(3-y)+2y=8.5
12-4y+2y=8.5
-4y+2y=8.5-12
-2y=-3.5
y=-3.5/-2
y=1.75
x=3-y
x=3-1.75
x=1.25
Answer: The price of one soft pretzel is $1.75.
