Answer:

∠MON = 99

Step-by-step explanation:

∠LON = 180°

∠MON + ∠LOM = 180 -------equation

where:

∠MON = 8x - 13

∠LOM = 7x - 17

plugin values into the equation

8x - 13 + 7x - 17 = 180

8x + 7x - 13 - 17 = 180

15x - 30 = 180

15x = 180 + 30

x = 210 / 15

x = 14

plugin values to ∠MON = 8x - 13

∠MON = 8x - 13

∠MON = 8(14) - 13

∠MON = 99

Solve √(2x+3)=x for x showing work

marishachu [46]

√(2x+3)²=x²
2x+3 = x²
x²-2x-3 = 0
(x-3)(x+1) = 0
x-3=0 and x+1=0
x = 3,-1

What is the quotient of (x cubed 3 x squared minus 4 x minus 12) divided by (x squared 5 x 6)? x 2 x – 2 x – 8 x 8

snow_tiger [21]

The quotient of the given expression is x-2. The correct option is the second option- x – 2

<h3>Simplification of fractions </h3>

From the question, we are to determine the quotient

The given expression is

$\frac{x^{3}+3x^{2} -4x-12 }{x^{2} +5x+6}$

The numerator can be expressed as

$(x-2)(x^{2} +5x+6)$

Then, the fraction becomes

$\frac{x^{3}+3x^{2} -4x-12 }{x^{2} +5x+6}$ = $\frac{(x-2)(x^{2} +5x+6)}{x^{2} +5x+6}$

Simplifying

$\frac{(x-2)(x^{2} +5x+6)}{x^{2} +5x+6} = x-2$

Hence, the quotient of the given expression is x-2. The correct option is the second option- x – 2

Ralph is an electrician. He charges an initial fee of $26, plus $31 per hour. If Ralph earned $119 on a job, how long did the jo

lubasha [3.4K]

3 hours

You can turn this into an equation:

F = 26 + 31t
Where F is the money Ralph earned, and t is the number of hours he worked.

Plugging in the 119 for F, we get
119 = 26 + 31t

93 = 31t

3 = t
