Answer:
Martina 29, Scott 23 and Jim 69.
Step-by-step explanation:
We are told that:
Martina served six more X orders than Scott (X+6).
So, Scott served X orders.
And Jim served 3 times X order as Scott.
We will have then:
X + (X+6) + 3X = 121
5X + 6 = 121
5X = 121 - 6
5X = 115
X = 115/5
X = 23
So, Scott served 23 orders, Martina 29 and Jim 69.
Step-by-step explanation:
3n+4n=-14
now add 3n and 4n
7n = -14
divide both by 7
n = -2

Answer:
Step-by-step explanation:
x = number of pushups he did
The question asks for the rate of toys per hour.
So we shall divide the total toys assembled by the total hours.
Its a five day week.
The number of hours allotted per day are 8.
So total allotted during the week are 8 × 5 = 40 hours.
Number of toys made during the week are 400.
Hence the number of toys assembled per hour per person
= number of toys / number of hours
= 400 / 40
= 10 toys per hour per person.
The average number of toys assembled per hour per person is 10.
