The ? Is 11.
You add the equations to get rid of one variable, then you have 6x=24 then you divide both sides and you have x=4, then you substitute the given value of x and you are left with 5*4 - y = 9. And the solution or well possible solution is y = 11 which gives youuuuu. (x , y) = (4 , 11)
Answer:
Step-by-step explanation:
*Assuming commas are used for decimals.
<h3><u>Given that:</u></h3>
2.6 kg potatoes = R 13.20
<h3>Using unitary method</h3>
Divide 2.6 to both sides
1 kg potatoes = R 13.20/2.6
1 kg potatoes = R 5.1
Multiply 3.3 to both sides
3.3 kg potatoes = R 5.1 × 3.3
3.3 kg potatoes = R 16.75

Square:
We know all sides of a squares are equal in length.
s= the length of one side of the square.
45= s+s+s
45= 3s
s=15 inches
Each side of the square is 15 inches.
Rectangle:
length(l)= ????
Width(w)= s = 15 inches
l -w= 5inches
l- (15 inches)= 5 inches
l = 20 inches
Answer:
A length of the rectangle is 20 inches long.
Answer:
2178 square inches
Step-by-step explanation:
5'6" means 5 feet and 6 inches.
1 foot = 12 inches, that means that you have 66 inches ((5*12) + 6).
2'9" are 33 inches.
The area of a rectangle is given by: A=L*W, then we have: A = 66 inches * 33 inches.
A=2178 square inches.
