Hi , the answer is 105/2
15 equals to 15/1
We switch the second fraction to 7/2
Then we multiply straight across
15x7=105
1x2=2
Answer:
d. 50° (not between sides), 5 in, 3 in none? one? or more than one?
more than one
i. 6 ft, 79° (angle between sides), 2 ft none? one? more than one?
none
j. 9°, side 5 m (between angles), 72° none? one? more than one?
one

Answer:
length of each plan A work out: 1 hour
length of plan B work out: hours
Step-by-step explanation:
Let x represents the time taken to do plan A
y represents the time taken to do plan B
On Monday there were 5 clients who did Plan A and 2 who did Plan B.
Miguel trained his Monday clients for a total of 6 hours
5x + 2y = 6 -----------> equation 1
On Tuesday there were 3 clients who did Plan A and 8 who did Plan B. .He trained his Tuesday clients for a total of 7 hours
3x + 8y = 7 -------------------> equation 2
Now we solve for x and y
Let multiply the first equation by -4 to eliminate y
-20x -8y = -24
3x + 8y = 7
------------------------ (add both equations)
-17x = -17
Divide both sides by -17
So x= 1
Plug in 1 for x in first equation and solve for y
5x + 2y = 6
5(1) + 2y = 6
5 + 2y =6
Subtract 5 on both sides
2y = 1
y = 1/2
length of each plan A work out: 1 hour
length of plan B work out: hours
