21 Last year Chelsea and Sonya took 236 pictures during Thanksgiving. This year Chelsea and Sonya each took the same amount of p
Leokris [45]

Let 'c' represent the number of pictures Chelsea took.

Let 's' represent the number of pictures Sonya took.

For last year's Thanksgiving, c + s = 236

For this year's Thanksgiving, let 'x' represent the number of photos taken in total. x = c + s, where c and s are two integers that are the same (c = s).

And we know that for both years, c + s + x = 500.

As we know that c + s is already 236 from last year, we can remove c + s from the equation in bold and replace it with 236 instead.

236 + x = 500.

Now we have to isolate the x term.

x = 500 - 236

x = 264.

We know that x = c + s, where c and s are the same, so we can just use one of the variables and double it (so you either get 2c or 2s - it doesn't matter which one you pick because they're both the same).

2c = 264

c = 132

c = s

s = 132.

Both took 132 pictures this year.

The Martinez family walked three over five of a mile in three over eight of an hour. What equation can be used to calculate thei
jolli1 [7]
Velocity=distance/time

v=d/t

So in this case:

v=(3mi/5)/(3hr/8)  that's the equation you need to solve.

v=(3m/5)*(8/3hr)

8/5 mph=(3m/5)*(8/3hr)

1 3/5 mph= (3/5)/(3/8)

So the first statement is correct.
