Answer:
Xavier has 5 dollars
Step-by-step explanation:
2x represents how much money Alex had, the -3 is how much he spent, and the 7 is how much he has now
Add 3 to both sides
divide both sides by 2
Checking my work:
$495-15%=$420.75
$420.75+8%=$454.41
he will pay $454.41 is he uses the coupon
The horizontal distance is given by the formula:
tan θ=opposite/adjacent
where:
θ=21
opposite=2000 ft
adjacent=a
thus calculating for a we get:
tan 21=2000/a
thus
a=2000/tan 21
a=5210.18 ft
Answer: 5210.18 ft

Answer:
6 : 5
Step-by-step explanation:
The diagram shows you that the boxes have a length (L) to width (W) ratio such that ...
3L = <em>l</em> = 4W
L/W = 4/3
Suppose we call the width of the box 3 units, then its length is 4 units, and we have the crate dimensions ...
<em>l</em> = 4(3) = 3(4) = 12
<em>w</em> = 3+3+4 = 10
Then the ratio <em>l </em>: <em>w</em> is 12 : 10 = 6 : 5.
9(5)+8=53
All you have to do is plug 5 in for x
