Which of the following statements show correct ways to find
vekshin1

Answer:b and e

Step-by-step explanation:because b is  (7x200)-(7x2) which =1386

                                                                    1400     -    14   =1386 which is 7x198=1386

e because (7x100)+(7x90)+(7x8)

                    700   +  630  + 56 = 1386

Find the point of intersection of the pair of straight lines.
Ber [7]

Answer:

(x,y) = (\frac{9}{2},\frac{1}{2})

Step-by-step explanation:

We have to find point of intersection of two lines.

the given equations of line are:

10x - 4y = 43 - (1)

-3x - 3y = -15 - (2)

Multiplying the first equation by 3 we have:

(10x - 4y = 43)×3 = 30x - 12 y = 129 - (3)

Multiplying second equation by 10 we have :

(-3x - 3y = -15)×10 = -30x -30y = -150 - (4)

Now, adding equation (3) and (4)  we have:

-42y = -21

⇒ y = \frac{1}{2}

Now, putting this value of y in equation (1), we have

10x - 2 = 43

⇒ 10x = 45

⇒x = \frac{9}{2}

Hence, the intersection of given two lines is (x,y) = (\frac{9}{2},\frac{1}{2})
