30:60:90 is 3:6:9 in ratio form
Hi, Sthefy! This is just a little bit of adding, not too hard! Okay, 5 tens. What is 1 ten equal to? 10!
2 tens? 20!
3 tens? 30!
You get the idea? Okay, so now we know that 5 tens are 50. Now, ones. All we need to do now is add 13 + 50! Let's break it down, make it easier.
13.. Hm, what can we do to make this easier?
Ah! Take away the 3 from 13 for now. So just 10 + 50. That's 60. Now, add the 3. 63! That wasn't hard, was it? I hope I helped you!
13g + 2(4k - g)
Distributive property
13g + 8k - 2g
Put like terms 2gether
13g- 2g + 8k
11g + 8k
THE ANSWER IS 11g + 8k
First you need to find how many grams is 1 ounce. 1o z.is 28.35 g, then you need to multiply 28.35 g by 5 which is 141.75. you need to round it to the nearest hundred so it is about 142 grams.
the key here would be
1 oz. = 28.35g or 1 oz. = 28 g
Hope this helps!
