Solve the proportion. 2/3/4 = 10 LO x = [?]

Setler79 [48]

Answer:

x = 6

Step-by-step explanation:

We want to find x,

$\frac{3}{5} = \frac{x}{10}$

to get x alone, we multiple both side by 10

$\frac{3}{5} * 10 = \frac{x}{10} *10$

$\frac{30}{5} = x$

30 divided by 5 is 6

Check:

We can see that 5 x ____ = 10 where ____ is 2

5 x 2 = 10

so 3 x 2 = 6

Please help. Indices and Standard Form question

brilliants [131]

Answer:

A= 4.5×10^11

B= 3.5×10^3

Step-by-step explanation:

(5×10^3)= 5000

(9×10^7)=90000000

multiply both of them

=450000000000 or 4.5×10^11

(7×10^5)=700000

(2×10^2)=200

700000÷200

3500 or 3.5×10^3

Given f of x is equal to the quantity x plus 3 end quantity over the quantity x squared minus x minus 12 end quantity and g(x) =

Westkost [7]

From the given f(x) and g(x), the value of (g-f)(2)=1

Given :

The functions are

$f(x)=\frac{x+3}{x^2-x-12} \\g(x)=log_4(x)$

Lets evaluate (g-f)(2)

$(g-f)(2)=g(2)-f(2)$

To find out g(2), replace 2 for x in g(x) and then replace 2 for x in f(x)

$f(x)=\frac{x+3}{x^2-x-12} \\g(x)=log_4(x)\\x=2\\f(2)=\frac{2+3}{2^2-2-12}=\frac{5}{-10}=-\frac{1}{2} \\\\g(2)=log_4(2)=\frac{1}{2}$

Now we find g(2)-f(2)

$(g-f)(2)=g(2)-f(2)=\frac{1}{2}-\frac{-1}{2} =1$
