Answer:
and 
Step-by-step explanation:
the perimeter of a rectangle is given by the following equation:
if a rectangle has a perimeter of 76cm and its length is 5 plus the double of its width we can use a system of equations to find the length 
, and the width 
.
For the perimeter of the rectangle
where is its length, and is its width, 76 is the perimeter of the rectangle in cm.
We know that the lengh of the rectangle is 5 plus the double of its width, writing the equation:
Substituting the equation above in
We got that the rectangle width is w=11cm
Substituting w in the equation
We got that the rectangle length is l=27cm
Verifying the values obtained
with l=27 and w=11
Satisfying the equation
Answer:
[-16 20 -24].
Step-by-step explanation:
4[-4 5 -6]
= [4*-4 4*5 5*-6]
= [-16 20 -24].
Answer:
the first
Step-by-step explanation:
because it's common sense you can obviously see.
Answer:
A large pizza costs $5 and a small pizza costs $3.
Let 'x' be the number of large pizzas and 'y' the number of small pizzas. We have that:
x + y = 150
5x + 3y = 570
Solving the system of equations:
x + y = 150 → 3x + 3y = 450 → 3y = 450 - 3x
5x + 3y = 570 → 5x + 450 - 3x = 570
2x = 120
x = 60
y = 150 - 60 = 90
Therefore. Carmen y Carlos will make 60 large pizzas and 90 small pizzas.
Answer:
D (9)
Step-by-step explanation:
2 was one unit apart from 3 and the from the 6 polygon with the 2 is 3 times the 2 and since it is 3 times 2 variable has to be 3 times 3 which is 9 (D).
