Answer:
answer 13.33333 hours h
Step-by-step explanation:
Julia studied 3 1/3 hours during 4 days
this means she studied:
3 1/3 of 4 days of 24 hours
3 1/3 = 9/3 x 1/3 = 10/3
and 4 days of 24 hours is 4 x 24 = 96
there for
10/3 x 96 = (10/1)x32 =320 hours
320/24 hours each day -13.3333
Kelly's regular pay is $10 per hour and overtime pay is $20 per hour.
<h3>What is equation?</h3>
The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign. A mathematical statement known as an equation is made up of two expressions joined together by the equal sign. A formula would be 3x - 5 = 16, for instance. Solving this equation, we get the value of the variable x as x = 7.
Here,
Let her regular pay be x and overtime pay be y.
8x+4y=160
y=x+10
8x+4(x+10)=160
8x+4x+40=160
12x=120
x=10
y=x+10
=10+10
=20
Kelly receives a regular pay rate of $10 and a $20 overtime pay.
