The ratio that comes next in the sequence is 8:23.

<h3 /><h3>Definition of a ratio</h3>

Ratio expresses the relationship between two or more numbers. It shows the frequency with which one value is contained in another value.

<h3 /><h3>How to determine the numbers that come next</h3>

Looking at the first ratio in the sequence, the number on the left increases by 1 in the second ratio. In the second ratio, the number on the left increases by 2 and for the third ratio. The difference between the third and fourth ratio is 1 for the number on the left. This shows that the sequence for the numbers on the left is 1, 2, 1. Thus the next number would increase by 2.

Looking at the first ratio in the sequence, the number on the right increases by 4 in the third ratio. In the fourth ratio, the number on the right increases by 4 when compared with the third ratio.  This shows that the sequence for the numbers on the right is an increase by 4.

Lola has twice as many quartes and half as many nickels as does ellen. ellen
mylen [45]
So
eq=ellen's quarters
en=ellens's nickles
lq=lola's quarters
ln=lola's nickles
lq/2=eq or lq=2(eq)
2(ln)=en or ln=en/2
en+eq=$6.30 or 630 cents
en+6nickles=eq
so nickle=5 so
5*6=30
630-30=600
number of nicles=number of quarters of  lola=600
nickle+quater=30
600/30=20
20 quarters
20+6=26 nickles
elen has 20 quarters and 26 nickles

20 times 2=40 quarters
26 divided by 2=13 nickles
lola has 40 quarters and 13 nickles

40 times 25=1000 cents in quarters
13 times 5=65 cents in nickles
1000+65=1065 cents or $10.65=lola's money

mr_godi [17]

Answer:

3

Step-by-step explanation:

When you go from x=1 to x=3 you go up twice on the x-value. The y value also increases by 6 which means all you have to do is find the average.

6/2= 3

3 is the average increase between x=1 and x=3

Hope this helps!
