Answer: there were 854 buttons in bag a
Step-by-step explanation:
4342 = a + b + c
b = a + 18
c = 3b
4342 = a + (a + 18) + 3(a + 18)
4342 = a + a + 18 + 3a + 54
4342 = 5a + 72
-72 -72
4270 = 5a
/5 /5
854 = a
Remember, an=a1(r)^(n-1) where a1=first term or where n=1 and r=commmon ratio
<span>
</span>
a2/a1=r
<span>
</span>
so if you have the graph, find the y value coresponding to x=1 and that is a1
<span>
</span>
find the y value coresponding to x=2 and taht is a2, do a2/a1 to get r
so like I was saying
well, each term is 1/2 of the previous
20/40=1/2
so r=1/2
and a1=40
so

is da equation
(this is for fractions!!!!!!!!!!!!) 28/5 or 5 3/5
i think u just make it into 5.6/1 multiply by 10 which gets 56/10 and wala
but it's not simplified. 56 and 10 is divisible by 2 so u get 28/5 which is actually 5 3/5 (which is 5.6!!)
Answer:
No the ratio 3:4 is not equal to 4:5
Step-by-step explanation:
3:4 = 3/4 and 4:5 = 4/5
3/4 is equal to 0.75 and 4/5 is equal to 0.8
0.75
0.8
therefore, 3:4
4:5
Hope this helps!
