Answer:
-1/3x+2y=4
Step-by-step explanation:
Substitute the negative reciprocal.
-1/3x+2y=4
Answer: B
Explanation:
We can substitute burgers for m and drinks for p, since all burgers are the same price and drinks are the same price, substitute the 3 burgers and 2 drinks into
3m+2p
The only right answer for this equation is $13.50, substitute the 5m+4p=$23.50 and your only right answer is B
Answer:
Option (4)
Step-by-step explanation:
To calculate the volume of a pyramid we use the formula,
V = 
Area of the square base = (Side)²
= (6)²
= 36 square ft
Height of the pyramid 'h' = 
[By Pythagoras theorem]
h = 
h = 
h = 4 ft
Therefore, volume of the given pyramid = 
= 48 cubic ft
Option (4). 48 ft³ will be the answer.
I think it is B. Hope this helps!
To solve this problem, you can create a system of equations and solve for each hiker's distance walked.
Hiker 1 distance walked: x
Hiker 2 distance walked: y
Their combined distance walked is 53 miles, thus -
x + y = 53
The difference between miles walked is 25, thus -
x - 25 = y
Let's solve using substitution. To do that, substitute x - 23 into x + y = 53 for y.
x + y = 53
x + (x - 25) = 53
x + x - 25 = 53
2x - 25 = 53
2x = 78
x = 39
To find y, substitute 39 for x into either of the equations.
x + y = 53
39 + y = 53
y = 14
Finally, check all work.
x + y = 53
39 + 14 = 53
53 = 53
x - 25 = y
39 - 25 = 14
14 = 14
Answer:
One hiker walked 39 miles and the other hiker walked 14 miles.
