Answer:
1.25 Hours (1 hour & 15 minutes)
Step-by-step explanation:
14x = 5 + 10x
Subtract 10x from both sides
4x = 5
Divide by 4 on both sides
x = 1.25
It will take 1 hour and 15 minutes (1.25 hours) for Mrs. Penn and Mrs. Smith to be paid the same amount.
Volume = h × l × b
= 3.6 × 2.1 × 1.5
= 11.34 m³
21
y = 3x + 9
y = -3x + 12
y=21
For this case we must find the inverse of the following function:
To do this, we follow the steps below:
We exchange the variables:
We clear the variable "x" (the variable is already cleared):
We change "x" to "y":
We change y for :
