Answer: x = 115/2 and 119/6

You can simplify the answer.

Step-by-step explanation:

(2x + 5)(6x -1)= 120

120 = (2x +5) and (6x -1) = 120

120 - 5 = 2x and 6x = 120 - 1

115 = 2x and 6x = 119

115/2 = x and x = 119/6

Answer:

=>(2x+5)(6x-1)=120

=>2x(6x-1)+5(6x-1)

=>12x>2-2x+30x-5=120

=>12x>2+28x-5-120=0

=>12x>2+28x-125=0

fgiga [73]

Answer:

$\sqrt{-6 + \frac{y}{3}} = x$

Step-by-step explanation:

y = 18 + 3x²

- 18 - 18

__________

$\frac{-18 + y}{3} = \frac{3x^2}{3} \\ \\ -6 + \frac{y}{3} = x^2 \\ \\ \sqrt{-6 + \frac{y}{3}} = x$

To complete this component you will need to insert parentheses in Expression 2 to change the order of operations so the expressi

Alika [10]

Given:

The expression is $5+4\times 2+6-2\times 2-1$ .

To find:

The position of parentheses inserted in the expression to get the value 19

Step-by-step explanation:

We have,

$5+4\times 2+6-2\times 2-1$

Now,

$(5+4)\times 2+6-2\times 2-1=9\times 2+6-4-1$

$(5+4)\times 2+6-2\times 2-1=18+6-5$

$(5+4)\times 2+6-2\times 2-1=18+1$

$(5+4)\times 2+6-2\times 2-1=19$

There are more ways to apply the parenthesis, but we do not get 19.

$5+4*\left(2+6\right)-2*2-1=32\neq 19$

$5+4*2+\left(6-2\right)*2-1=20\neq 19$

$5+4*2+6-2*\left(2-1\right)=17\neq 19$

And many more possibilities.

Therefore, the expression after inserting the parentheses is $(5+4)\times 2+6-2\times 2-1$ .
