Hmmm the increase, wel is just the difference 367 - 312, which is 55.
now, if we take 312 to be the 100%, what is 55 off of it in percentage?
Answer:
The awnser is Incorrect
Step-by-step explanation:
So do the Parentheses first (4x2)=8
12-4=8
12-2=10
Now do your multiplcation 8x10=80
Subtract 12-8=4
So the awnser is incorrect
Answer:
50
Step-by-step explanation:
You would have worked 6 hours as lifeguard and 8 hours as cashier.
8(14 - y) + 6y = 96
112 - 8y + 6y = 96
112 - 2y = 96
-2y = -16
y = -16/-2 = 8
You worked 8 hours as a cashier. since the total hours worked is 14 we know you worked as a lifeguard for 6 hours.
We know the value absolute of x is possible x if x positive or -x if x negative.
So we have two cases:
* 5x+4=14 or 5x=14-4, and 5x=10, x=10:5 and we obtain x=2
* 5x+4=-14 or 5x=-14-4, and 5x=-18, so we have x= -18:5
So we choose c, 2, -18/5
