(3b + 12 ) divided by 2 =30 Whats is b ?

1 answer:

6 0

b=16 , First you multiply 30 by 2 to see what sum you need for the numerator. Then you subtract the 60 that you get by the 12 and get 48. So 3 multiplied by b should give you 48. So you just divide 48 by 3 and get 16.

What is 1/2 of 2 3/4?

luda_lava [24]

Answer:

1 3/8

Step-by-step explanation:

First, change the mixed fraction to improper fraction.

2 3/4 = 8/4 + 3/4 = 11/4

1/2 of 11/4 = (11/4)(1/2) = 11/8

11/4 - 11/8 = 22/8 - 11/8 = 11/8

11/8, or 1 3/8 is your answer.

Give brainliest! Right triangle ABC is on a coordinate plane. Segment AB is on the line y = 2 and is 3 units long. Point C is on

Anastasy [175]

Answer: y coordinate is 6

Step-by-step explanation:

6=1/2(3)(h)

If you solve for H then

h=4

So, add 4 to the line y=2

y=2+4

2+4= 6

Hence, the possible y coordinate of point C is 6

Hope this helped!

I would really appreciate if marked brainlest !

Thank you !

What is the inverse of the function f(x) = x + 2?

nadya68 [22]

Answer: $h(x)=x-2$

Step-by-step explanation:

To find the inverse of the function $f(x) = x + 2$ , the first step is to replace f(x) with "y":

$f(x) =y= x + 2\\\\ y = x + 2$

The second step is to solve for the variable "x":

$x=y-2$

The third step is to interchange the variables, then:

$y=x-2$

Finally, let be h(x) the inverse of the function f(x). Then, you can replace "y" with h(x). Therefore, this is:

$h(x)=x-2$
