Answer:

Step-by-step explanation:

Direct variation problems can easily be solved with proportions, namely:

$\frac{x}{y} :\frac{2}{5}=\frac{4}{y}$ and cross multiply to get

2y = 20 so

y = 10

sukhopar [10]

Answer:

→Step 1:

$\frac{6}{9} + \frac{6}{9}$

write the equation

→Step 2:

$\frac{6 + 6}{9}$

after taking LCM of 6/9 and 6/9 we get( 6+6)/9

→step 3:

$\frac{12}{9}$

after adding 6 and 6 we get 12

→Step 4:

$\frac{4}{3}$

after dividing numerator and denominator by 3 we get 4/3

→step5:

$1.334$

finally we get 1.334✓

hope it helped you:)

3x^2 – 8x + 5 = 5x^2

Ghella [55]

Answer:

Step-by-step explanation:

$3x^2 -8x +5 = 5x^2\\\\5x^2 - 3x^2 + 8x -5 =0\\\\2x^2 +8x -5 = 0\\\\$

a = 2, b = 8, c = -5

$x = \frac{-b \pm \sqrt{b^2 -4ac} }{2a}\\\\x = \frac{-8 \pm \sqrt{8^2 - ( 4 \times 2 \times (-5))} }{2 \times 2}\\\\x = \frac{-8 \pm \sqrt{64 +40} }{4}\\\\x = \frac{-8 + \sqrt{64 +40} }{4} \ , \ x = \frac{-8 - \sqrt{64 +40} }{4}\\\\x = \frac{-8 + \sqrt{104} }{4} \ , \ x = \frac{-8 - \sqrt{104} }{4}\\\\x = \frac{-8 + \sqrt{4 \times 26} }{4} \ , \ x = \frac{-8 - \sqrt{4 \times 26} }{4}\\\\x = \frac{-8 +2 \sqrt{26} }{4} \ , \ x = \frac{-8 - 2\sqrt{26} }{4}\\\\$
