Answer: 3/13
Step-by-step explanation:
-3 (h-6) = 5 (2h + 3)
-3h + 18 = 10h + 15
-3h - 10h + 15 - 18
h (-3-10) = 15 - 18
h (-13) = -3
h = -3/-13
3/13
Answer:
1/3
Step-by-step explanation:
We are given ...
barrettes : hair ties = 5 : 7
barrettes : hair bands = 5 : 8
Then the combined ratios are ...
barrettes : hair ties : hair bands = 5 : 7 : 8
For every 5 barrettes, there are 7+8 = 15 hair ties and bands, so their ratio is ...
barrettes/(hair ties and bands) = 5/15 = 1/3
The answer is 21g hope this helps :)
