Answer:

let,

breadth = x

length = 2x+2

perimeter= 2 ( L+ b) for a rectangular swimming pool.

154 =2(2x+2+x)

154 = 6x+4

6x = 150

x = 25

thus, breadth= x= 25 m

length = 2x+2= 52m

Klio2033 [76]

Answer:  x=5\textdegree

Explanation:

Since we have given that

line m and line n are parallel to each other,

So,

Corresponding angles are equal , as shown in the figure ,

According to question,

19x\textdegree=180\textdegree-17x\textdegree\\\\19x\textdegree+17x\textdegree=180\\\\36x\textdegree=180\textdegree\\\\x=\frac{180}{36}\\\\x=5\textdegree

Hence, x=5\textdegree

PLEASE HELP
poizon [28]
Part A
The given line passes through (-2,2) and it is parallel to the line

4x - 3y - 7 = 0


We need to determine the slope of this line by writing it in slope -intercept form.


3y = 4x - 7


y =  \frac{4}{3} x -  \frac{7}{3}
The slope of this line is
\frac{4}{3}


The line parallel to this line also has slope

m =  \frac{4}{3}


The equation is

y =  \frac{4}{3} x + c


We substitute (-2,2)

2 =  \frac{4}{3}( - 2)  + c


c = 2 + \frac{8}{3}  =  \frac{14}{3}


The required equation is


y =  \frac{4}{3} x + \frac{14}{3}


PART B


The given line is


4x - 3y - 7 = 0




The slope of this line is
\frac{4}{3}


The slope of the line perpendicular to it is

m = -  \frac{3}{4}

The equation of the line is

y =  -  \frac{ 3}{4} x + c




We substitute the point, (-2,2)



2=  -  \frac{ 3}{4} ( - 2) + c


2=  \frac{ 3}{2}  + c



c = 2 -  \frac{3}{2}  =  \frac{1}{2}


The equation of the perpendicular line is


y=  -  \frac{ 3}{4} x +  \frac{1}{2}

Use any method to add or subtract 5/7 {3/14+3/14}
OlgaM077 [116]

Answer:

15/49

Step-by-step explanation:

5/7 (3/14 + 3/14)

first combine like terms

3/14 + 3/14 = 6/14

then simplify by 2

6/14 to 3/7

now that both the term inside and outside have the same denominator, multiply

5/7 x 3/7 = 15/49
