Multiply everything by -3 so it will be n-15>4 then add 15 to both sides so it will be n>19 and thats the answer.
Velocity=distance/time
Data:distance=10 Km=10 km*(0.621 miles/1 km)=6.21 miles.time=55 minutes
Velocity=6.21 miles/55 minutes=0.11290909... miles/minute≈0.113 miles/ minute
Data: distance=1 mile.velocity=0.113 miles/minute
time=distance /velocitytime=(1 mile) / (0.113 miles/ minute)=8.85668... minutes≈8.86 minutes.
Answer: D 8.86 minutes.
Answer: Andre picked 252 pounds of apples
Step-by-step explanation:
Let x = number of pounds of apple picked by Jane.
Let y = number of pounds of apple picked by Andre
Let z = number of pounds of apple picked by Maria
Andre picks three times as many pounds as maria. It means that
y = 3z
Jane picks two times as many pounds as Andre. It means that
x = 2y
The total weight of the apples is 840 pounds. It means that
x + y + z = 840 - - - - - - - - - 1
We will substitute z = y/3 and x = 2y into equation 1
2y + y + y/3 = 840
Cross multiplying with 3
6y + 3y + y = 2520
10y = 2520
y = 2520/10 = 252
x = 2y = 252× 2 = 504
z = y/3 = 252/3 = 84
The formula is SA = bh + (s1 + s2 + s3)H
The answer is 420m^2
I hope this helps! :)

Answer:
The verbal model and an algebraic expression representing Lindsay's total salary for the week is $400 + 0.15 <em>d</em>.
Step-by-step explanation:
The base salary of Lindsey is, <em>B</em> = $400.
The commission she earns on every sale made by her is, <em>c</em> = $0.15.
It is provided that Lindsey makes <em>d</em> dollars during the week.
The amount <em>d</em> dollars is the total commission earned by Lindsey in a week.
The formula to compute the commission earned will be represented by the expression:
<em>C</em> = <em>c</em> × $<em>d</em>
= 0.15 <em>d</em>
The expression represent Lindsay's total salary for the week is:
Total Salary = Base Salary + Total Commission
= B + C
= $400 + 0.15 <em>d</em>
Thus, the verbal model and an algebraic expression representing Lindsay's total salary for the week is $400 + 0.15 <em>d</em>.
