Answer:
x=6
Step-by-step explanation:
When you have 7x+5=5x+17, you try to get the variables on one side and the constants on the other. Subtract 5x from the right and from the left: 2x+5=17. Next, subtract 5 from the left and from the right: 2x=12. The last step is to get rid of the coefficient of x and to do that divide it by the coefficient(in this case divide both sides by 2). After dividing 2x and 12 by 2 you get x=6.
To answer this we need to divide 12,000 by 10 and our answer will be the tenth of 12,000. Then we will check our work. Lets do it:-
12,000 ÷ 10 = 1,200
1,200 is the tenth of 12,000.
CHECK OUR WORK:-
1,200 × 10 = 12,000
We were RIGHT!!
So, 1,200 is the tenth of 12,000.
Hope I helped ya!!
(3/2)*(3/4) = (3*3)/(2*4)=(9/8) which is the same as 1 whole 1/8
Explanation:
The N stands for Pi so when you type in the answers to Khan Academy use the Pi symbol when theres an N! These are the common questions and common radius Khan Academy gives when they ask to find the radius of the circle.

For 2 - 33.49
Step-by-step explanation:
<u><em>I did the go math so all of these rights and the majority of the answers are the questions Khan Academy will ask you to find the radius of the circle.</em></u>
Answer: x = 11
To start, we know that a whole circle equals 360 degrees. If we subtract the 2 arcs we know, 85 and 31, we have 244 degrees left for the 2 congruent arcs. Dividing that by 2 gives us 122 for each arc.
Now, write the equation: 122 = 13x - 21
Solve this, to find the x = 11.
