Let me see if I can decipher that :P
3/(3x)+1/x+4=10/(7x) first we need to make all terms have a common denominator of 21x...
(21+21+84x)/(21x)=30/(21x) multiplying both sides by 21x leaves you with
21+21+84x=30 combine like terms on left side
42+84x=30 subtract 42 from both sides
84x=-12 divide both sides by 84
x=-1/7
Answer:
43
Step-by-step explanation:
Area for rectangle is A=b×h
You can only multiply radicals with other radicals so... √17×√68= √1156
Simplify radical
√1156= 34
Then add 9
34+9= 43
We can see that a and b are parallel, and c and e are parallel, so the correct option is E.
<h3>
Which line must be parallel?</h3>
On the diagram, we can see that the angles in the third quadrant of the intersections between a and c, and the intersections between b and c, are the same angle.
Then, lines a and b must be parallel.
For the intersections with line d, we can see that this time the angle is on the fourth quadrant, so c and d are not parallel.
Finally, for line e, we can see that the known angle is on the first quadrant.
Notice that the angle on the first quadrant will be equal to the angle on the third quadrant.
So for the intersections of a and e, and b and e, on the third quadrant we have the known angle (the same one as in the intersections of a and c, and a and b).
Then c and e are parallel.
Then A and C are true.
Thus, the correct option is E.

Answer:
There are about 80 students age 15 and above take a car to school.
Step-by-step explanation:
1. For all the columns the total has been given.
2. Bus is taken as 60 as walk/bike has been given 65 under age 15.
3. 195 row total Age 15 and above has been provided and updated.
4. Walk/Bike 152, 65 is already given Age 15 and above difference is 87.
5. Bus 60 under age 15 is already given total 110 difference is 50.
6. Age 15 and above 65,50,195 (Total) is already given row difference is 80.
7. Car is Age 15 and above is 80 and Total column is 98 difference is 18.
8. Age 15 and above take car is 80.
