What is 1 3/4 - 5/6r =8/3

fenix001 [56]

1 3/4 - 5/6r = 8/3

-5/6r + 7/4 = 8/3

-5/6r +7/4 - 7/4 = 8/3 -7/4
-5/6r = 11/12

(6/-5)*(-5/6r)=(6/-5)*(11/12)
=-11/10

r = -1 1/10

Solve |5x+30|=10x ......

Orlov [11]

Answer:

Option A

Step-by-step explanation:

We need to solve out ,

$\implies |5x + 30| = 10x$

We can write it as ,

$\implies 5x + 30 = \pm 10x$

On simplyfing further,

$\implies 5x + 30 = 10x \quad or \quad 5x +30=-10x$

On solving the above equation , we will get ,

$\implies \boxed{ x = 6,-2}$

Now we know that the value of modulus is never negative so when we will put x is equal to 2 on the RHS we will get -20 which is not possible . Therefore , the extraneous root is -2 .

Option A is correct .

Write your answer in standard form. (6x+7) (x-8)

WITCHER [35]

Answer:

First one is d and second one is c

Step-by-step explanation:

(6x+7)(x-8)

(6x)(x) = 6x^2

(6x)(-8) = -48

(7)(x) = 7x

(7)(-8) = -56

Add all like terms together and you get choice d.

(w+3)(w-3)

(w)(w) = w^2

(w)(-3) = -3w

(3)(w) = 3w

(3)(-3) = -9

Add all like terms together and you get choice c
