Answer:

n=4

Step-by-step explanation:

step 1: Simplify both sides of the equation.

4n−1=6n+8−8n+15

4n+−1=6n+8+−8n+15

4n−1=(6n+−8n)+(8+15)(Combine Like Terms)

4n−1=−2n+23

Step 2: Add 2n to both sides.

4n−1+2n=−2n+23+2n

6n−1=23

Step 3: Add 1 to both sides.

6n−1+1=23+1

6n=24

Step 4: Divide both sides by 6.

6n/6=24/6

The sum of the measures of angle X and angle Y is 90. If the measure of angle X is less than twice the measure of angle Y, what

Tatiana [17]

X+y=90
x<2y
x+y< 3y
but x+y=90
90<3y
⇒ y>30
for example y=31, then x= 59
y=32, x= 58
.............................................
y=40, x=50

Solve the equation using the quadratic formula.

BabaBlast [244]

The value of x is -9 and 3.Option D.

Step-by-step explanation:

Given,

$-x^{2} +27 = 6x$

To find the value of x.

We will apply middle term factor formula.

The given equation can be written as,

$x^{2} +6x-27 = 0$

or, $x^{2}$ +(9-3)x-27 = 0

or, x²+9x-3x-27= 0

or, x(x+9)-3(x+9)=0

or, (x+9)(x-3) = 0

So, x = -9 and x = 3

Hence,

The correct option is Option D.
