Answer:
c) <u>m = 5p-4</u>
Explanation:
Given that function A is : x → +4 → ×2.
A(x) = 2(x+4).
Given that function B is: x → ÷5 → +1.
B(x) = x/5 + 1.
To find the working variables for:
m → Function A → Function B → 2p + 1.
Create this composite function: B(A(x)) = 2(x+4)/5 + 1
Then set x equal to m and solve for the working equation to 2p + 1
_______________
(simplify)
2(m+4)/5 + 1 = 2p + 1
-1 -1
________________
2(m+4)/5 = 2p
÷2 ÷2
___________
(m+4)/5 = p
×5 ×5
_________
(m+4) = 5p
-4 -4
________
<u>m = 5p - 4</u>
She will have 150 in 5 days because 120÷4=30 30+120=150
2y - 4x = 5.....add 4x to both sides
2y = 4x + 5....divide both sides by 2
y = 2x + 5/2 <==
Answer:The wall is 8 ft wide and the picture frame is about 2 ft wide. The sides of the picture frame will be about (8-2)/4 = 3 ft from each wall.
However, since the picture frame is actually 22 inches wide, the exact distance would be (8*12 - 22)/2 = (96 - 22)/2 = 74/2 = 37inches (3 ft 1 inch) from the wall.
Solve the problem by first subtracting the width of the picture frame from the width of the wall. That will give the length of the wall that is not covered by the frame, or the "free length". Since the picture is centered in the width of the wall, there will be an equal distance from the frame to the wall on each side of the frame. Divide the free length by 2 to get the distance from the frame to the wall. Hope its helps ;)
Well this is -5-9 basically this is integers case 3 of subtraction
