Hey there, hope i can help!

\mathrm{Add\:}99\mathrm{\:to\:both\:sides}  \ \textgreater \  11x-99+99=201-x+99

Simplify
11x=-x+300

\mathrm{Add\:}x\mathrm{\:to\:both\:sides} \ \textgreater \  11x+x=-x+300+x

Simplify again
12x = 300

\mathrm{Divide\:both\:sides\:by\:}12 \ \textgreater \  \frac{12x}{12}=\frac{300}{12}

Simplify once more
x = 25

Hope this helps!

Solve: (3√8x - 2 )= 4<br> To solve this equation, first<br> _____both sides.<br> x =_____
PIT_PIT [208]

Answer:

Add 2 to each side

x=1/2

Step-by-step explanation:

(3√8x - 2 )= 4

Add 2 to each side

(3√8x - 2 +2= 4+2

3√8x = 6

Divide each side by 3

3/3√8x = 6/3

√8x = 2

Square each side

(√8x)^2 = 2^2

8x = 4

Divide each side by8

8x/8 = 4/8

x = 1/2

A border of uniform width is placed around a rectangular photograph that measures 8 inches by 10 inches. If the area of the bord
amid [387]

Answer:

width of the border is 3 inches

Step-by-step explanation:

Given data

size = 8 inches by 10 inches

area = 144 square inches

to find out

width of the border

solution

first we consider width of border is x

area of new full rectangle =  (8 + 2x ) × ( 10 + 2x )

so we know  area of photo = 8 × 10 = 80 square inches

and area of border = 144 square inches that is given

so new area of photo with the border is 80 + 144 = 224 square inches

and we can say that

area of full rectangle  - area of the photograph = Area of Border

(8 + 2x) × (10 + 2x) – (80) = 144  square inches

80 + 16x + 20x + 4x^{2} – 80 = 144

4x^{2} + 36x – 144 = 0

solve thios equation we get  

2x^{2} + 9x – 36 = 0

solve thios equation we get  

(x + 12) (x – 3) = 0  

so here x have two value one is negative and other is positive

so we consider only positive value

x = -12 or x = 3

width of the border is 3 inches
