2x+3=x+x+3<br> Show your work
Nitella [24]

Step-by-step explanation:

2x+3=x+x+3

add the X's on the right side together.

2x+3=2x+3

subtract 2x from both sides

3=3

subtract 3 from both sides

0=0

the statement is true for any value of x

Cynthia Besch wants to buy a rug for a room
77julia77 [94]

The length and width of the rug is 20 and 11 feet respectively

The given parameters;

dimension of the room = 19 ft by 28 ft

maximum area of rug she can afford = 220 ft²

For a uniform stripe of floor around the rug, then suppose the uniform excess length of the floor to removed from each dimension = y

(28-2x)(19-2x)=220

532-94x+4x^2=220

4x^2-94x+312=0

x=39/2,4

For x=39/2, dimensions are negative.

The uniform dimension of the floor to be covered by the maximum area of rug she can afford = (28 - 4×2) and (19 -2×4 ) = 20 and 11

Thus, the dimensions of the rug should be 20 feet and 11 feet

X-5y=2 and 9x+8=15 solve by substitution
lozanna [386]
x-5y=2
Hence x=2+5y   (Equation I)
9x+8=15             (Equation II)
Substituting Equation I in Equation II
9(2+5y)+8=15
18+45y+8=15
26+45y=15
45y=-11
Hence y= - \frac{11}{45}

Substituting this in Equation in I to get X

x-5(- \frac{11}{45} )=2
x+ \frac{11}{9}=2
x= 2- \frac{11}{9}
x= \frac{17}{9}
