Step-by-step explanation:
all the ways you could do it so it would be 0
x-4y+5z=0,x+z-3y=0
6x-y+4z=0,x-7y+z=0
Tim would have to do 18 chores (2 chores 9 times or 1 chore 18 times) to be able to buy the video game.
Step-by-step explanation:
Step 1; Tim's parents will give him $3 for every two chores. This equals $1.50 for a single chore. He wants to save up $27 so that he can buy the video games he wants.
Step 2; The number of times he has to do the chores to be able to but the video game is a division between the money he wants to save up by the money he gets for the chores.
Number of 2 chores he needs to do = Amount of money he wants to save up / money he gets for doing two chores
= $27 / $3 = 9 times.
Number of single chores he has to do =Amount of money he wants to save up / money he gets for doing two chores
$27 / $1.50 = 18 times
We can start with "All real number," then we eliminate certain value what would cause zero in denominator;
Here, we have denominator of √(2x+8)
We need to exclude value of x from real number such that √(2x+8) = 0 So solve for x here;
√(2x+8) = 0
[√(2x+8) ]² = 0²
2x+8 = 0
2x = -8
x = -4
So we cannot have x to be -4, otherwise denominator would be zero.
So exclude -4 from "All real number"
Now we have domain of (-∞, -4) U (-4, ∞) or All real number; x ≠ -4.
Answer:
<u>The width of the rectangle is 4.8 inches</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Area of the rectangle = 12 square inches
Length of the rectangle = 2.5 inches
2. What is the width?
We will find out the width, this way:
Width * Length = Area of the rectangle
Replacing with the real values, we have:
Width * 2.5 = 12
Width = 12/2.5
<u>Width of the rectangle = 4.8 inches</u>
First, we can order the set in ascending order to get
76,77, 77, 78,79, 82, 82 ,84, 84, 87, 90, 95, 97, 100.
A stem-and-leaf plot has the tens digits on the left side, and the units digits on the right side, so this set would look like
7 | 6, 7, 7, 8, 9
8 | 2, 2, 4, 4, 7
9 | 0, 5, 7
10 | 0
