Answer:
34
Step-by-step explanation:
Add them together
5x+10=180
5x+10-10=180-10
5x=170
5x/5=170/5
x=34
set up the equation like so
7+15.50x=100
-7 -7
15.50x=93
then divide 93 by 15.50
and youll get 6 as your answer.
she can bring 6 people
Answer:
Step-by-step explanation:
Both numbers of the ratio units used to express the ratio in ten years are 2 higher than at present. Thus, each ratio unit must stand for 5 years. That would make their current ages ...
Sunitha: 7·5 = 35
Raseeda: 8·5 = 40
_____
If you can't figure the answer right away from the change in ratio units, then you may need to write a couple of equations:
- s/r = 7/8
- (s+10)/(r+10) = 9/10
These can be translated to standard form, which may make some methods of solution easier:
These have solution (r, s) = (40, 35).
