Eighteen less than a number is 44:before you answer this question you must have to think about a equation, which makes easy for you to answer these kind of questions.
look, here the question tells us that x-18=44, so the answer will be:
x-18=44
x=44-18

Answer:
(2,7) is not a solution to the given system of equations.
Step-by-step explanation:
Given system of equation is:
2x + 3 = y
2x + y = 15
To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.
Putting x=2 and y=7 in Eqn 1
2(2) + 3 = 7
4 + 3 = 7
7 = 7
Thus the ordered pair satisfies the equation
Putting x=2 and y=7 in Eqn 2
2(2) + 7 = 15
4 + 7 = 15
11 ≠ 15
The ordered pair do not satisfy the second equation.
Hence,
(2,7) is not a solution to the given system of equations.
Area of rectangle is base times height
area of triangle is 1/2 times base times height
this shape has 3 rectangular sides and 2 triangular sides
2 sides and 1 bottom
2×(6×5)+1×(6×8) = 108
front and back triangular sides
2×(1/2)×(3×8) = 24
total is 132 cm^2, C
2x + 2x + 124 + 124 = 360
4x + 248 = 360
2x = 360 - 248 = 112
x = 112/2 = 56
