If the fraction 391/x-10 is equivalent to -23, find the value of x

Mathematics

x = - 7

multiply both sides by (x - 10) to eliminate the fraction

391 = - 23(x - 10 ) ← ( distribute parenthesis )

391 = - 23x + 230 ← ( subtract 230 from both sides )

161 = - 23x ← ( divide both sides by - 23 )

\frac{161}{- 23} = x

- 7 = x ⇒ x = - 7

Slove system of equations y=2x-3 y=x^2-2x-8
Fiesta28 [93]

Answer:

2 solutions:

x=5 and y=7

x=-1 and y=-5

Step-by-step explanation:

y=2x-3

y=x^2-2x-8

y=y   so:

2x-3=x^2-2x-8

simplifying to:

x^2-4x-5=0

factoring to:

(x-5)(x+1)=0

x=5 or x=-1

if x=5 then y=2(5)-3=7

if x=-1 then y=2(-1)-3=-5

What is 3% in decimal form
AfilCa [17]
To convert a decimal into a percentage, first we have to convert it into fractional form.  

Because percentages are out of 100, the resulting fraction would be 3/100.

Next, to find the decimal, we would just divide the fraction (numerator divided by denominator).

3 % = 3/100 = 0.03
