Answer: 9 energy drinks and 18 granola bars.
Step-by-step explanation:
Price per granola bar = $0.50
Price per energy drink = $2.
We can define G as the number of granola bars that she bought, and D as the number of drinks that she bought.
Then
"She buys twice as many granola bars as energy drinks."
G = 2*D
" If she spends $27 in total"
G*$0.50 + D*$2 = $27
So we have a system of equations:
G = 2*D
G*$0.50 + D*$2 = $27
The first step will be to replace the first equation into the second one, and solve it for D.
(2D)*$0.50 + D*$2 = $27
D*(2*$0.50) + D*$2 = $27
D*$1 + D*$2 = $27
D*$3 = $27
D = $27/$3 = 9.
So she bought 9 energy drinks, and we know that:
G = 2*D
G = 2*9 = 18
She bought 18 granola bars.

Answer:
The length of the BM is 6 unit.
Step-by-step explanation:
Given : M is the centroid of the triangle. CM=7, PM=10, & BQ=18
To find : The value of BM ?
Solution :
Refer the attached figure below.
The centroid of a triangle is the point of intersection of its medians.
M is the centroid and the centroid divide the line in 1:2 ratio.
So, M divide BQ in 1:2 ratio and the total length of BQ is 18.
BM is one third of 18.
i.e.
Therefore, the length of the BM is 6 unit.
Problem
The perimeter of a rectangle is less than 10 inches. The length is x and the width is x - 5. If the solution is x<5, ThEn the length is less than 5. Is this viable solution.
Solution
For this case the perimete rof a rectangle is given by:
P= 2x+2y
x= lenght y = width
And we also know that y= x-5
And replacing the condition given: P<10 we got:
2x +2y <10
2x +2(x-5)<10
4x -10 >10
And we can rewrite as:
4x >20
x>5
So then the best answer would be:
B. non viable
To solve the question, we will estimate how many times Titicaca was larger than Texcoco. Here we shall use the formula:
(Area of Titicaca)/(Area of Texcoco)
Area of Titicaca=3.232×10^4
Area of Texcoco=2.1×10^3
thus the number of times <span> as great is the area covered by Lake Titicaca as opposed to the Lake that the Aztecs built on
(3.232</span>×10^4<span>)/(2.1</span>×10^3<span>)
=15.391 times</span>
