How to turn a fraction into a percentage?

Brilliant_brown [7]

Convert the fraction to a decimal number. The fraction bar between the top number (numerator) and the bottom number (denominator) means "divided by." So converting a fraction such as 1/4 to a decimal means you need to solve the math: 1 divided by 4.

-16.68 + 1.8s + 2.2 = 3s - 6.4

zlopas [31]

Answer:

s = -6.7

Step-by-step explanation:

- 16.68 + 1.8s + 2.2 = 3s - 6.4

- 16.68 + 2.2 + 1.8s = 3s - 6.4

- 14.48 + 1.8s = 3s - 6.4

Collect like terms

Note: crossing over equals to, the sign will change

Hint: either from

- to +

+ to -

-14.48 + 6.4 = 3s - 1.8s

-8.08 = 3s - 1.8s

-8.08 = 1.2s

Divide both sides by 1.2, to get the value of s

-8.08/1.2 = 1.2s/1.2

-6.7 = s

s = -6.7

Anna35 [415]

Answer:

x = 8/5

Step-by-step explanation:

first multiply both side by -1, it makes both side positive

1x/2 = 4/5

now multiply both sides by 2 to get the x by itself

x = 8/5

if they want improper fraction x = 1 $\frac{3}{5}$

What are the center and radius of the circle defined by the equation x^2 + y^2 -6x + 4y + 4=0

Sloan [31]

The equation of a circle:

$(x-h)^2+(y-k)^2=r^2$

(h, k) - a coordinates of the center

r - a radius

$x^2+y^2-6x+4y+4=0\ \ \ |-4\\\\x^2-2\cdot x\cdot3+y^2+2\cdot y\cdot2=-4\ \ \ |+3^2\ |+2^2\\\\\underbrace{x^2-2\cdot x\cdot3+3^2}_{(a-b)^2=a^2-2ab+b^2}+\underbrace{y^2+2\cdot y\cdot2+2^2}_{(a+b)^2=a^2+2ab+b^2}=-4+3^2+2^2\\\\(x-3)^2+(y+2)^2=3^2$

Answer:

the center: (3, -2)

the radius: 3
