32 is 40% of what number

anzhelika [568]

40% = 40 / 100 = 0.4

32 is 40% of what

= 32 / 40

= 32 / 0.4

= 80

U can also use this equation to solve it.

32 = 40%x

Simplfy

= 32 = 2/5x

Flib the equation.

2/5x = 32

Multipy both sides by 5/2

(5/2) * 2/5x = (5/2) * 32

x = 80.

Answer:

Step-by-step explanation:

3x² - 3x + 7 = 0

a = 3 ; b = -3 and c = 7

D = b² - 4ac = (-3)² - 4*3*7

D = 9 - 84 = - 75

D = 75i²

√D = √75i² = $\sqrt{5*5*3 * i * i}= 5i\sqrt{3}$

$x = \dfrac{-b+\sqrt{D}}{2a} \ ; \ x=\dfrac{-b-\sqrt{D}}{2a}\\\\ \\x=\dfrac{3+5i\sqrt{3}}{6} ; \ ; x = \dfrac{3-5i\sqrt{3}}{6}\\\\\\x =\dfrac{3}{6}+\dfrac{5i\sqrt{3}}{6} ; \ ; x=\dfrac{3}{6}-\dfrac{5i\sqrt{3}}{6}\\\\\\Solution:\\\\x=\dfrac{1}{2}+\dfrac{5\sqrt{3}}{6}i ; \ ; x=\dfrac{1}{2}-\dfrac{5\sqrt{3}}{6}i$

Rewrite equation -6x+3y=-18

chubhunter [2.5K]

Answer:

Step-by-step explanation:

assuming your rewriting it in slope-intercept form

-6x + 3y = -18 slope-intercept form is y = mx + b so we must get it in that format

first we divide the 3 from 3y but whatever we do to that we must so to all so -6x and -18 are also going to be divided by 3 and you will get

-2x + y = -6 after dividing everything by 3

now you want to add 2x to the left side to cancel out that -2x but whatever you do to one side you must do to the other so its going to be

y = 2x - 6

This should be your answer hope this helps

y = 2x - 6
