I'm assuming that x 8 = x⁸ and 3x 5 = 3x⁵.
So let's solve.
x⁸ + 3x⁵ = x⁵(____)
x⁸ + 3x⁵ = x⁵(x³ __)
x⁸ + 3x⁵ = x⁵(x³ + 3)
Therefore the missing expression is (x³ + 3)
Sup fam
Gallon of gas be x
4x=20
x=5
per gallon=32m
with 5 gallon=32*5=160
Answer:
B
Step-by-step explanation:
multiply both sides by 2 to eliminate the fraction
- x > 12
multiply both sides by - 1
Remembering to reverse the inequality symbol as a consequence
x < - 12 ← reverse symbol
⇒ { x | x ∈ R, x < - 12 } → B
Answer:
3.4 minutes
Step-by-step explanation:
Every morning there are expected 240 customers who arrive at bank for the customer service. There are on average 240 customers arriving to the bank every morning. There are total 5 bank tellers and they take average 3 minutes to help customer. The average time each bank teller spends on satisfying a customer will be calculated using the linear model,
Using wait time calculator:
Average service time / standard deviation
Ce = 3/1.5 = 2
The spent time on a customer is 3.4 minutes.
M = - 3 + 9 / 6 + 4
m = 6 / 10
m = 3/5
- 3 = 3/5 ( 6 ) + c
- 15 = 18 + 5c
5c = - 33
c = - 33/5
y = 3/5x - 33/5
