Answer:
B
Step-by-step explanation:
both sides are equal to begin with so any x that you put in, will get multiplied by 7 and have 3 added to it
Step-by-step explanation:

15 - c = 6
15 - 6 = c
9 = c
c = 9

Step-by-step explanation:
The principal will have to increase the number of teachers next year.
We found out that the seventh grade enrollment was 120% of the number of eight graders, which is greater than 110%.
219. 445 tickets are what you start off with. Multiply that by .6 (three-fifths) to find how many are sold. 226 were sold which means 219 are remaining unsold.
Answer:
Step-by-step explanation:
as given j=h and k=m then which expression for g is
as from attached image , we can see that its look like two right angle triangle
so from lower triangle we apply the pythagorean theorem .
which state that sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse.
so small triangle ΔEBD
h² +k²= g² ---------------(1)
now from big triangle ΔABC
(j + h)² +(m + h)² =f²---------(2)
given j=h and k=m so from equation-2 we can find ,
(h + h)² +(k+ k)² =f²
(2h)² +(2k)²=f²
4h²+ 4k²= f²
4(h²+k²)= f² ----------(3)
now from equation 1 and 3 we can obtained .
4×g² =f²
take square root both side we get,
2×g=f
so g=f/2----- Answer
