Answer:
Step-by-step explanation:
The given inequality is
Add 4 to both sides of the first inequality and subtract 5 from both sides of the second inequality.
We simplify to get:
Divide through the first inequality by 4 and the second by 9.
Answer:
1 and 3/4 days are equal to 42 hours
Step-by-step explanation:
42 hours = (42 hours) (1 day / 24 hours)
42 hours = 42/24 days
Simplyfing the fraction: Dividing the numerator and denominator by 6:
42 hours = (42/6) / (24/6) days
42 hours = 7/4 days
42 hours = (4+3)/4 days
42 hours = (4/4+3/4) days
42 hours = 1 3/4 days
Answer: Found it by web and solving
Step-by-step explanation: L = W + 4
LW = 60
---
LW = 60
(W + 4)W = 60
W^2 + 4W + (-60) = 0
---
above is in quadratic equation form: ax^2 + bx + c = 0
---
use the quadratic formula to solve for two solutions:
x = ( -b +- sqrt( bb - 4ac ) ) / 2a
---
the two solutions are:
W = 6
W = -10
the negative solution doesn't make sense for length, so use the positive solution.
---
L = 10
W = 6
Hi :)
Let's remember some arithmetic w/ negative integers :
a+(-b)=a-b
a-(-b)=a-b
Now
8-(-9)=8+9=17
So the answer's 17
I hope this helps
