N = number of hours.
$5 per hour, total = 5*n = $5n
Since $35 has been saved.
The amount saved plus the amount got from baby sitting should be greater or equal to the $90 cost.
5n + 35 ≥ 90
5n ≥ 90 -35
5n ≥ 55
n ≥ 55/5
n ≥ 11
So Rodney should baby sit for at least 11 hours, that is 11 and above.
Answer:
15p + 3
Step-by-step explanation:
Multiply 3 by each number in the parentheses and keep the variable
-4x-2y = 16
2y = -4x-16
Get one variable alone on both equations
-4x - 16 = 2y
-4x - 16 = 2y
You'll realize that they're the same equation.
Use substitution
-4x-16 = -4x-16
0 = 0
x = all solutions
Use x = all solutions in an earlier equation to find y
-4x - 16 = 2y
SInce x can be all solutions y is also all solutions
y = all solutions

Answer:
n = 60
Step-by-step explanation:
GIVEN DATA:
Total sum of consecutive number is 1800
sum of n number is given as
where n is positive number and belong to natural number i.e 1,2,3,4,...
from the data given we have
solving for n we get
[/tex]n^2 + n -3600 = 0[/tex]
n = 59.5, -60.5
therefore n = 60
