Answer:
Infinite Amount of Solutions
Step-by-step explanation:
Since we have concurrent systems (same slope + same y-int), we know that the systems of equations would be the <em>exact</em> same line. If that is the case, the we would know that ANY value input would work. You could even test it mathematically, and it would give you infinite amount of solutions.
X= fancy, y= plain
x+y= 7
28x+ 15y=131
solve by substitution
To find the area of a triangle given its base and its height, use the formula A = bh/2.
The base of the triangle is 14m.
The height of the triangle is 10m.
Plug these values into the formula and solve.
A = bh/2
A = 14(10)/2
A = 140/2
A = 70
Answer:
The area of the triangle is 70 m².
Answer:
5 pack notebook
Step-by-step explanation:
5 pack notebook costs more because the 4 pack notebook costs 4 dollars w/ 2 cents off, and 5 pack notebook costs 5 dollars and with 1 cent of, so if ir increase by 1 dollar, than probably the 5 pack costs more. It is not about how many, but how much dollars are for per/ notebook.
