Answer:

A=24, B=40, P=60

Step-by-step explanation:

<em>given: </em>

<em>P+A+B=124</em>

<em>2P+B=160</em>

<em>P+2A+2B=188</em>

___________

P=188-2A-2B

P=124-A-B

188-2A-2B=124-A-B

188-A-B=124

188=124+A+B

A+B=64

___

P+A+B=124

P=60

___

2P+B=160

120+B=160

B=40

___

A+B=64

A=24

___

If we substitute each variable in the three given equations for these values, the equations hold true. Therefore, these are the correct values.

Solve: 2/3x - 3/4 = 5 + 5/6x
Slav-nsk [51]

Answer:

\large\boxed{x=-\dfrac{69}{2}\to x=-34\dfrac{1}{2}\to x=-34.5}

Step-by-step explanation:

\dfrac{2}{3}x-\dfrac{3}{4}=5+\dfrac{5}{6}x\qquad\text{multiply both sides by LCD = 12}\\\\12\!\!\!\!\!\diagup^4\cdot\dfrac{2}{3\!\!\!\!\diagup_1}x-12\!\!\!\!\!\diagup^3\cdot\dfrac{3}{4\!\!\!\diagup_1}=(12)(5)+12\!\!\!\!\!\diagup^2\cdot\dfrac{5}{6\!\!\!\diagup_1}x\\\\(4)(2x)-(3)(3)=60+(2)(5x)\\\\8x-9=60+10x\qquad\text{add 9 to both sides}\\\\8x-9+9=60+9+10x\\\\8x=69+10x\qquad\text{subtract}\ 10x\ \text{from both sides}\\\\8x-10x=69+10x-10x\\\\-2x=69\qquad\text{divide both sides by (-2)}\\\\x=-\dfrac{69}{2}

A rectangular piece of sheet metal is 4 ft longer than it is wide. (see the illustration.) the area of the piece of sheet metal
pshichka [43]
This is the start to the approach that would be taken to get both variables in terms of only one so it can be solved but since the numbers are so small you could easily test out numbers and figure out that it's 6 and 10 feet.

length = width + 4

length * width = 60
(width + 4) * width = 60
