Hey!
91 ÷ 7 = 13
So, we know that Luke paints one portrait every week.
13 × 4 = 52
So, Luke paints 52 portraits in 4 weeks.
After 3 hours each strain will have been depleted completely to 0 cells. Given the numbers 6000 and 2000, you will find that a decrease of 33.33333% for strain A and a 50% decrease for strain B will not intercept on the same hour. Strain B will have been depleted for an hour at the time that strain A is gone.
Answer:
When
solving distance problems we will use the relationship rt = d or rate (speed) times
time equals distance. For example, if a person were to travel 30 mph for 4 hours.
To find the total distance we would multiply rate times time or (30)(4) = 120.
Step-by-step explanation:
I do K12 7th grade and it has really brought my grades up! One thing I have noticed though is the work is more advanced then the work at a normal school. At first I had alot of trouble getting used to the system but after awhile it's very simple.

Answer:
The numbers are 12 and 19.
Explanation:
x - first number
y - second number
{x + y = 31
{x = y + 7
{x + y = 31
{x - y = 7 (+)
----------------------------
x + x + y - y = 31 + 7
2x = 24
x = 12
{x = 12
{12 + y = 31
{x = 12
{y = 19
