Answer:
Her regular weekly pay is $62 and her annual salary is $3100.
Step-by-step explanation:
Given that her hourly wage=$15.50 / hour
As she works 40 hours per week, so her weekly pay = 15.50 x 40 = $62/ week.
If she works 50 weeks each year, so her yearly pay = 62x50=$3100 /year.
Hence, her regular weekly pay is $62 and her annual salary is $3100.
Answer:
y = -4/5x + 14/5
Step-by-step explanation:
Point (6,-2) and (-4,6)
Slope = (6- - 2) / (-4-6) = 8 / -10 = - 4/5
(The slope is negative because La línea is going downhill. Uphill is positive)
You can also find the slope in the graph: rise/run.
y-intersect (any point)
Point (6, -2) (any point)
y-Intercept: -2 - (-4/5)(6) = -2 + 24/5 = 14/5
7:4
or
7/4

Answer:
nickels = 12
quarters = 9
Step-by-step explanation:
Let number of quarters be "q", and
number of nickels be "n"
Nickels are worth $0.05 and Quarters are worth $0.25
Since all of them are worth 2.85, we can write:
0.25q + 0.05n = 2.85
Also, we know, there are 3 more nickels than quarters, so we can write:
n = 3 + q
Now, we can substitute equation 2 into equation 1 to get:
Now, we solve for q:
There are 9 quarters.
We know n = 3 + q
So,
n = 3 + 9
n = 12
There are 12 nickels
The linear equations are:
- The price of oil from 1990: y = 30 + 5x
- The price of oil from 2005: y = 20 + 2.25x
<h3>How to determine the linear equations</h3>
A linear equation is represented as: y = mx + c
Where:
- m represents the rate
- c represents the initial value.
At the beginning of 1990, we have the following parameters
- Rate: m = 5
- Initial value: c =30
So, the linear equation is:
y = 30 + 5x
At the beginning of 2005, we have the following parameters
- Rate: m = 2.25
- Initial value: c =20
So, the linear equation is:
y = 20 + 2.5x
Hence, the linear equations are y = 30 + 5x and y = 20 + 2.5x
