Answer:

The answer to your question is x = -1

Step-by-step explanation:

15 - 5(365x) = 1840

Process

1.- Subtract 15 in both sides of the equation

15 - 5(365x) - 15 = 1840 -15

2.- Simplify

-5(365x) = 1825

3.- Divide by -5 both sides

-5(365x)/-5 = 1825/-5

4.- Simplify

365x = -365

5.- Divide by 365 both sides

365x/365 = -365/365

6.- Simplify

x = -1

Answer:

Step-by-step explanation:

Subtract 15 in both sides of the equation

15 - 5(365x) - 15 = 1840 -15

-5(365x) = 1825

Divide by -5 both sides

-5(365x)/-5 = 1825/-5

-365x=365

Divide by 365 both sides

365x/365 = -365/365

x = -1

Answer check:

substitute for (x)

15-5(365(1))

15-5(365)

distribute -5

15-(-1825)

two negative becomes positive

15+ 1825

= 1,840

Please help me find n. 1/3=n+3/4

raketka [301]

Answer:

-5/12

Step-by-step explanation:

Let's solve your equation step-by-step.

1 /3 = n + 3 /4

Step 1: Flip the equation.

n + 3 /4 = 1/ 3

Step 2: Subtract 3/4 from both sides.

n+ 3 /4 − 3/4 = 1/ 3 − 3 /4

n= −5 /12

Select the two values of x that are roots of this equation.<br> 2x+11x+15= 0

Amiraneli [1.4K]

Answer:

The roots of the equation are x=-3 and x=-2.5

Step-by-step explanation:

<u><em>The correct quadratic equation is</em></u>

2x^2+11x+15=0

we know that

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$ is equal to

$x=\frac{-b(+/-)\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$2x^{2} +11x+15=0$

so

$a=2\\b=11\\c=15$

substitute in the formula

$x=\frac{-11(+/-)\sqrt{11^{2}-4(2)(15)}} {2(2)}$

$x=\frac{-11(+/-)\sqrt{121-120}} {4}$

$x=\frac{-11(+/-)\sqrt{1}} {4}$

$x=\frac{-11(+/-)1} {4}$

$x_1=\frac{-11(+)1}{4}=-2.5$

$x_2=\frac{-11(-)1}{4}=-3$

therefore

The roots of the equation are x=-3 and x=-2.5
