If karen works 85 hours within two weeks and earns $1,891.25, you'd set up an equation like this, to find the value of x ----
x=amount of money per hour Karen works
85x=<span>1,891.25
then divide </span><span>1,891.25 by 85
x=</span>22.25
this says that karen gets $22.25 for every hour she works.... then to find how much she works for 8 hours you want to multiply the amount of money she gets per hour by 8 hours.
22.25 x 8 = 178
Karen earns $178 after working 8 hours.

Answer:
n = 6
Step-by-step explanation:
you can create this proportion:
18/n = n/6
cross-multiply:
n² = 108
n = 
= 
·
· = 2·3· or 6
The answer is 140, you just add them up and it goes by 2.
Answer:
<em>- 112 + 100 n</em>
Step-by-step explanation:
= 
+ (n - 1 )d
~~~~~~~
= - 12
d = 100
= - 12 + 100( n - 1 )
= - 12 + 100n - 100
<em>= - 112 + 100 n</em>
