The number of boxes renita and Vanessa has unpacked each is 6 and 9 boxes respectively.
<h3>Equation</h3>
- Number of boxes renita has unpacked = x
- Number of boxes Vanessa has unpacked = 2x - 3
- Total boxes both unpacked = 15
x + (2x - 3) = 15
x + 2x - 3 = 15
3x = 15 + 3
3x = 18
x = 18/3
x = 6
Therefore,
Number of boxes renita has unpacked = x
= 6 boxes
Number of boxes Vanessa has unpacked = 2x - 3
= 2(6) - 3
= 12 - 3
= 9 boxes

Answer:
Step-by-step explanation:
The engineer can use a clinometer to measure the angle of elevation of the top of the tree. Let the height of the tree be represented by x, the she could determine the distance across the river, d, by applying the trigonometric function.
Tan θ = 
= 
the the distance, d = x ÷ Tan θ
Assume the angle of elevation of the top of the tree is 
, and the height of the tree is 10 m, then the distance, d, across the river would be;
d = 
= 17.3190
d = 17.32 m

Answer:
Rectangle
Step-by-step explanation:
if you split the shape in half vertically you won't get a circle, oval, and triangle isn't even anywhere in that picture.
so using the process of elimination it would have to be the first option. Rectangle.

You can either convert -3 into a fraction, or convert -2/5 into a decimal so you can solve this.
If you decide to convert -3, into a fraction, it would be -3/1, and you'd have to multiply that by the reciprocal of -2/5.
So, you'd have -3/1(-5/2)=15/2, which can be simplified to 7 1/2.
If you decide to convert -2/5 into a decimal, you would get -0.4. You would then divide -3 by -0.4, which is equal to 7.5.
Both 7.5 and 7 1/2 are correct answers, and if you were to convert 7.5 into a fraction and 7 1/2 into a decimal, you would notice that they are the same number, but in different forms.
