First, add all of the working hours.
1
+ 2
+ 1
Since the denominators are different, make them all the same.
1
+ 2
+ 1
Add everything together.
4
+ 1
= 5
Then, simplify.
5
or 5.5
Multiply the time by the salary.
<span>5.5*10.5=
Doug earned $57.75</span>
Answer:
$10
Step-by-step explanation:
divide $4 by 8. you get $.50. multiply that by 20 and you get $10
The graph of the solution to this inequality is: C. number line with an open circle plotted at negative eight and arrow pointing left.
<h3>What is a number line?</h3>
A number line simply refers to a type of graph with a graduated straight line which contains both positive and negative numbers (numerical values) that are placed at equal intervals along its length.
Next, we would solve the given inequality as follows:
−0.4b + 2.4 < 5.6
Subtracting 2.4 from both sides, we have:
−0.4b + 2.4 - 2.4 < 5.6 - 2.4
−0.4b < 5.6 - 2.4
−0.4b < 3.2
Dividing both sides by -0.4, we have:
b < -3.2/0.4
b < -8
In conclusion, the circle on a number line should be open and would point to the left when the inequality symbol is <.

The equation that could be used to find x, the average number of feet the tree grew each month is; 14x + 10 = 56.2
<h3>Algebra Word Problems</h3>
We are told that the tree was planted at a height of 10 ft.
Period for which tree was planted = 14 months
Height of tree after 14 months = 56.2 ft.
Thus, if x is the average number of feet the tree grew each month, then the equation to find x is;
14x + 10 = 56.2
