Let's make a system of equations.
1 large bottle = l
1 regular bottle = r
l + r = 113
221 = 2.5l + r
Isolate r in the first equation and substitute it into the second equation:
l + r = 113
r = 113 - l
---
221 = 2.5l + 113 - l
221 = 1.5l + 113
108 = 1.5l
72 = l
Now, substitute that back into the first equation:
l + r = 113
72 + r = 113
r = 41
Finally, check your work by substituting back into both equations:
72 + 41 = 113 --> 113 = 113 <-- True
221 = 2.5(72) + 41 --> 221 = 180 + 41 <--True
Answer:
Franklin sold 72 large bottle of water and 41 regular-sized bottles of water.
450 divides by 10 to receive a product of 45
Answer:
C (-6, 2)
Step-by-step explanation:
in order to solve this system of equation, we would say that let
y = 5x + 32................................equation 1
y = -4x - 22.........................................equation2
substitute equation 1 into equation 2
we have,
5x + 32 = -4x - 22
combine the like terms
5x +4x + 32 = -22
9x = -22-32
9x = - 54
divide both sides by the coefficient of x which is 9
9x/9 = -54/9
x = -6
put x =-6 into equation 1
y = 5x + 32................................equation 1
y = 5(-6) + 32
y = -30 + 32
y = 2
therefore the value of x and y is -6 and 2 respectively

Answer:
hope it works for u
Step-by-step explanation:
Given the length of the rectangle = l
the breadth of the rectangle = b
perimeter of the rectangle = sum of length of all sides of the rectangle
= l+ b+ l+ b
=2 l+2 b
=2( l+ b)
∴ perimeter of the rectangle =2( l+ b)
as given perimeter = 1004 m
hence ,
2(l+ b)= 1004
(l+ b)=1004/2 = 502 m
<h2>
l+ b=502 m</h2>
