Answer:

  a) 150-90 = h(15.25 -9.75)

  b) 10.91

Step-by-step explanation:

a) Jennifer has 150 -90 = 60 less in savings than Eduardo, but she is earning 15.25 -9.75 = 5.50 more per hour. An equation she can use to figure her hours is ...

  60 = 5.50h . . . . for h hours worked.

In 'raw' form, that might be ...

  150 -90 = (15.25 -9.75)h

__

b) Solving the above equation, we get ...

  60/5.50 = h ≈ 10.90909 ≈ 10.91 . . . hours

On easter morning 20 eggs were hidden kyla found 1/2 of them kevin found 1/4 of them what fraction of eggs were left to find
kotykmax [81]
\frac{1}{2}*20= 10 
 and \frac{1}{4}*20= 5
This means that Kayle found 10 eggs while Kevin found 5 eggs.
so 20-(10+5)= 5 eggs left.
To find the fraction, divide the number of eggs left over the number of total eggs.
Fraction= \frac{5}{20}= \frac{1}{4}

Hope this helps!
