jared=6hrs  

1/5+1/6=1/x       x= Time together

6x/30x+5x/30x=30/30x

11x=30

x= 2 8/11

What is the constant of proportionality between y and x in the graph?
umka2103 [35]

Answer:

So, The answer would be 1=k

Step-by-step explanation:

My step is to make a T-chart, as u make it put X on one side and Y on the other

So what i did was i put 0 for both of them because it had start at 0

then i followed the line to the dot as i did that It has 6,6 so then i figured out what multiply all those number and the answer was 1=k

And another way you could do it was to make 6,6 and fraction like 6/6 then divde them both and get 1=k

So you would put the answer as 1

thats it Answer-1

Given a line segment that contains the points A,B,& C in order, if AB = x + 12, and Bo2.4, and AC = 26 = ?
natulia [17]

Answer:

x=11.6

Step-by-step explanation:

According to the angle addition postulate, if B lies on AC, than AB+BC=AC.

We can use this to create this equation.

x+12+2.4=26 Where x+12 is the value of AB and 2.4 is BC.

The next step is to combine like terms, so we add 12 to 2.4 to get

x+14.4=26. When trying to find the value of a variable, you must isolate it. To do this for this equation, we must subtract 14.4 from both sides which will give you.

x=11.6

Hope this helps. If you have any follow-up questions or I misunderstood the question, please tell me and I will fix it or explain more.

Have a great day! :)

Write the value of n that makes statement true (3+n)+7=3+(6+7)
8_murik_8 [283]

Answer: n = 6

Step-by-step explanation:

First lets combine like terms

(3 + n) + 7 = 3 + (6 + 7)

10 + n = 16

Now let’s subtract 10 on each side to isolate x

N = 6

Now let’s check our work by inputting x just to make sure

(3 + 6) + 7 = 3 + (6 + 7)

9 + 7 = 3 + 13

16 = 16

So we are right!
