Answer:Enrqiue's average was higher than Rosario's average by 3
Step-by-step explanation:
Rosario's average= sum of 78, 77, 64, 86, and 70/ no of scores= 375/5= 75
Enrique's average=sum of 90, 61, 79, 73, and 87/ no of scores = 390/5=78
78-75=3
The intersection of the two equations is (1, 1/5). Since the question is asking for the value of x, x = 1.

Let's first break it down to the time 8 people need for one wall. That would be 10 minutes, right? If one person would have to do it in stead of 8, you'd expect him to take 80 minutes.
To paint 7 walls, he would nee 7x80 = 560 minutes. 10 people would do that 10 times faster, ie., 56 minutes.
I know puzzles like these always have a mindtrick. Did I miss anything?? ;-)
Answer:
z = 3.2 units
Step-by-step explanation:
sin 76°/z = sin 51°/2.6
cross-multiply to get:
z·(sin 51°) = 2.6·(sin 76°)
z = 2.6·(sin 76°) ÷ (sin 51°)
z = 3.2
