Answer:
She makes 7.50 per hour
Step-by-step explanation:
Let x = regular rate
Time and a half = 1.5x
40 hours at x
52-40 = 12
12 hours at 1.5x
40x + 12 * 1.5x = 435
40x + 18x =435
58x = 435
Divide each side by 58
58x/58 = 435/58
x =7.5
She makes 7.50 per hour
Answer:
Step-by-step explanation:
The equation of a line is usually written in the form of y=mx+c, where m is its gradient and c is its y-intercept.
First rewrite the equation of the given line in the form of y=mx +c.
4x+5y=25
5y= -4x +25
The gradient of the given line is 
The product of the gradient of perpendicular lines is -1.
Thus, m= 
Substitute a coordinate to find c.
When x= -4, y= -6,
Hence, the equation of the line is
<span>Josh swims 5 more hours per week than David so his hours = 3x + 5
His </span><span>average speed is 4 laps per hour less than David's so it is = x - 4
</span>
Total distance = hours * speed
= (3x + 5)*(x - 4)
= 3x^2 - 7x - 20
Ans is C
'of' means multiply
half a dozen means 12/2=6
6 of one thing means 6 times x
plus means ad
half a dozen of another mean 6 times y
they are added
6x+6y
2 variables
it says 'of the other' so they are diferent
