Alright, so 3f-g=4 and f+2g=5.
3f-g=4
f+2g=5
Multiplying the first equation by 2 and adding it to the second, we get 7f=13 and by dividing both sides by 7 we get f=13/7. Since f+2g=5, then we can plug 13/7 in for f to get 13/7+2g=5. Next, we subtract 13/7 from both sides to get 2g=3+1/7=22/7 (since 3*7=21 and 21+1=22). DIviding both sides by 2, we get 22/14=g. Plugging that into f/39g, we get (13/7)/(22*39/14)
= (13/7)/(858/14)
= (13/7)*(14/858)
=182/6006
= 91/3003 (by dividing both numbers by 2)
= 13/429 (by dividing both numbers by 7)
= 1/33 (by dividing both numbers by 13)
Answer:
c
Step-by-step explanation:
you would do
m = money overall
(m*1.08) +3000= you would do that twelve times
The answer to your question is 6.72.

Answer:
k = 0.167
Step-by-step explanation:
This is a direct proportion. That is as the number of chairs increases, so does the number of minutes needed.
y=number of chairs
x = time in minutes.
y = k x
4 = k * 24 Divide by 24
4/24 = k
You could leave it that way.
or you could do the division
k = 1/6 = 0.167
y = 0.167 x
the answer is c because
y=60° opposite angles of a parallelogram are congruent.
? = 180-52-60 co- interior
=68°
