To find the total amount earned, you need to multiply the number of hours worked by the pay rate. Joe worked x hours for 2 days. That’s 2x hours. He worked 8 hours for 2 days. That’s 8(2), or 16 hours. The total number of hours he worked is 2x + 16. He gets paid $9/hour, so an expression for the total amount earned is 9(2x + 16), or 18x + 144.

Answer:

Joe earns 18x+144 dollars that week with x being the number of unknown working hours on Wednesday and Friday.

Step-by-step explanation:

Joe earns $9/hour, On wednesday and friday he worked a total of 2x hours and on Tuesday and Saturday he worked a total of 16 hours. Let y be the amount of money Joe earned.

To determine how much money Joe earned we must determine how much hours he has work:

= 2*x+2*8=2*x+16

We can determine the amount earned from the total amount of hours work and rate of $9/hour:

y=(2*x+16)*9=18*x+144

Point C ∈ AB and AB=18 cm. The distance from C to A is 3 cm. shorter than the distance from C to B. Find AC and CB.
gogolik [260]

Answer:

AC=7.5 cm

CB=10.5cm

Step-by-step explanation:

Since we don't know the distance from C to B, we can label it as x. Our equation will be x+(x-3)=18. Simplify that so it is 2x-3=18. Add 3 to both sides and get 2x=21. x=10.5 So AC=7.5 cm and CB is 10.5 cm

Let A= {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}. Suppose an element of A is randomly selected. What is the probability that it belongs to
gregori [183]
<h3>Answer:  3/5</h3>

============================================================

Explanation:

The set {1, 2}U{2, 6, 7, 9}U{5, 6, 7} simplifies to {1,2,5,6,7,9} after we combine everything and sort the values. We toss any duplicates.

Let B = {1,2,5,6,7,9}

There are 6 items in set B out of 10 items in set A.

The probability of landing in set B, if you pick something randomly from A, is 6/10 = 3/5

Fine the equation of the line that is perpendicular to the given line and passes through the given point. Enter the right side o
Kipish [7]

Answer:

y=-\frac{4}{7} x+\frac{55}{7}

Step-by-step explanation:

Change the given equation to slope-intercept to get y=\frac{7}{4}x-\frac{1}{4}. When you multiply the slopes of perpendicular lines, you get -1. -1 divided by \frac{7}{4} is -\frac{4}{7}. The slope of the new line is then -\frac{4}{7}. The perpendicular line passes through (5, 5) so you can have the equation5=-\frac{4}{7} (5)+b. Simplifying gets b = \frac{55}{7} . So now the final equation for the perpendicular line is y=-\frac{4}{7} x+\frac{55}{7}
