11/20 + x = 9/10

x = 9/10 - 11/20

x = 18/20 - 11/20

x = 7/20

Answer:

x = 7/20

Step-by-step explanation:

11/20 +x= 9/10

Subtract 11/20 from each side

11/20-11/20 +x= 9/10-11/20

x = 9/10-11/20

We need a common denominator of 20

x = 9/10 *2/2 - 11/20

x =18/20 -11/20

x = 7/20

X/5=2/3=5/y 2/3 4/9 1

Mademuasel [1]

$\frac{x}{5}= \frac{2}{3} = \frac{5}{y}$
Break the equation into parts;
$\frac{x}{5} = \frac{2}{3} ; \frac{2}{3}= \frac{5}{y}$
Solving for x;
$\frac{x}{5} = \frac{2}{3}$
x= $\frac{10}{3}$
Solving for y;
$\frac{2}{3} = \frac{5}{y} 
y= \frac{3*5}{2} 
y= \frac{15}{2}$
$\frac{x}{y} = \frac{10/3}{15/2}$
$\frac{x}{y} = \frac{4}{15}$

Need help tremendously

Alina [70]

basically since 30 minutes is half of an hour, to get to a full hour you can multiply by 2, so you do that for both, 2/3 included so you get 2/3 * 2/1 4/3 is 1 1/3

F(x) = x^2+3; g(x) = square root of x-2 find f(g(x))

Anettt [7]

F(g(x)) = x + 1 . Just replace square root of x-2 to x in f(x)
