Answer:
$39.90
Step-by-step explanation:
if each video game cost $3.30, and she rented 7, then you multiply $3.30 by 7, to get $21.10, and if each DVD was $4.20, and she rented 4, then its $4.20x4= $16.80
after that you just add the two total costs together, which is $23.10+$16.80=$39.90
Answer:
Q. 2)Perimeter =2(l+b)
So,
2(8x-8 +8x)=80cm(Given in Question)
= 2*16x-8=80cm
16x- 8= 80 divided by 2,
16x=40+8=48
x=48 divided by 16
X=3
Q.1) Perimeter=2(l+b)
2(2x+8 +4x)=76cm(Given in Question)
2* 6x +8=76
6x+8= 76 divided by 2, 38
6x= 38-8, 30
x= 30 divided by 6 = 5
X=5

Answer:
length = 60 cm
Step-by-step explanation:
ratio of width : length = 3 : 4 = 3x : 4x
perimeter = (2 × width ) + (2 × length) = 6x +8x = 14x
now perimeter = 210, hence
14x = 210 ( divide both sides by 14 )
x = 15
hence length = 4 × 15 = 60 cm
