26/52 cards is red so that would be B.1/2
The total number of games played are 14 games played in total
Hoped i helped :)
For this case we have the following equation:

We want to solve the equation for the letter c.
To do this, we apply the distributive property:

Then, applying addition property of equality we have:

Then applying division property of equality we have:

Answer:
The value of c is:

2.75 hours.
The equation would be 32x + 46 = 134. So we subtract 46 from 134 and get 88. Now we have to divide that by 32 to get the total of 2.75 hours
I’m pretty sure you set the perimeters equal to each other, it would look like 3x+8+3x+7+3x = 3x+3x+4x+2 and then you add the similar ones so it would look like 9x+15 = 10x+2 then you subtract the two from both sides and subject the 9x from both sides and get 13 = x
AB would be 47
BC = 46
AC = 39
PQ = 39
QR = 39
PR = 54
then you could double check
47+46+39 = 39+39+54
132 = 132
