1/4(20-4a)=6-a (distribute 1/4)

5-a=6-a (subtract 5 to both sides)

-a=1-a (add "a" to both sides)

0=1

When this happens where the equation is not true, it means that a=no solution because there would be no "a" value that you could plug in to make the equation true.

Given Angle 1 = Angle 2,<br> find x.

drek231 [11]

Answer:

x = 6

Step-by-step explanation:

Given ∠ 1 = ∠ 2 then the segment is an angle bisector and the ratios of sides to base are equal, that is

$\frac{3}{x-4}$ = $\frac{x}{4}$ ( cross- multiply )

x(x - 4) = 12 ← distribute left side

x² - 4x = 12 ( subtract 12 from both sides )

x² - 4x - 12 = 0 ← in standard form

(x - 6)(x + 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 6 = 0 ⇒ x = 6

x + 2 = 0 ⇒ x = - 2

However, x > 0 , thus x = 6

To increase and amount by 17.5 which single multiplier would you use?

gavmur [86]

I suppose that the question is 17.5 %.

To increase an amount by a percentage, the multiplier is given by (100 + %)/100

Therefore, to increase an amount by 17.5%,
the single multiplier is given by (100 + 17.5)/100 = 117.5/100 = 1.175
