Answer:the width is 5 1/4 ft
Step-by-step explanation:
Step 1
The area of a rectangle is given as Length x width
Therefore the area of the rectangular board = Length x width
The length of the first board =6ft
The length of the second board =5 1/2 ft (5.5ft) with both having a total area of 60 3/8 (60.375ft²). To find the width of the boards since both have equal width, we use the equation
Length x width of board A + Length x width of board B= area of board A and Board B
6w + 5.5w =60.375
Step 2---- Solving the equation
6w + 5.5w =60.375
11.5w = 60.375
w = 60.375/11.5
w= 5.25
Therefore the width of the two boards are 5.25 ft / 5 and 1/4 ft each
Answer:
A and B
Step-by-step explanation:
The surface area is found by calculating the 6 faces of a 3-d object. Since A and B are the only ones that cause you to use the whole object for the given task the answers are A and B.
I think the answer to this question would be B
You plug in 1,2,3 and so on in the X and you graph , i think
2x-3y = -2 --------> (1)
4x + y = 24 -------> (2)
multiply equation number (1) by -2
-4x + 6y = +4
remove the x value from both equation (1) and (2) because its the same number and different sign
6y + y = 4 + 24
7y = 28
divide both by 7
y = 4
now putting y=4 in two equations
2x - 3y = -2
2x-3(4) = -2
2x-12 = -2
2x = -2 + 12
2x = 10
x = 5
or
4x + y = 24
4x + 4 = 24
4x = 24-4
4x = 20
x = 5
so its (5,4)
