Step-by-step explanation:

Determine the three numbers
We start by declaring the variables
Let the three numbers be [tex]x,\ y\ and\ z\ respectively[/tex]
Next, we write the relationships between the numbers
[tex]y = 2 * x[/tex] --- Second = Twice the first
[tex]z = 6 + y[/tex] --- Third = 6 more than second
[tex]x + y + z = 26[/tex] --- Sum of the three numbers
Then, we solve for each number
[tex]y = 2 * x[/tex]
[tex]z = 6 + y[/tex]
[tex]x + y + z = 26[/tex]
Substitute 6 + y for x in [tex]x + y + z = 26[/tex]
[tex]x + y + 6 + y =26[/tex]
Collect Like Terms
[tex]x + y + y = 26 - 6[/tex]
[tex]x + 2y = 20[/tex]
Substitute 2 * x for y in [tex]x + 2y = 20[/tex]
[tex]x + 2(2*x) = 20[/tex]
[tex]x + 4*x = 20[/tex]
[tex]x + 4x = 20[/tex]
[tex]5x = 20[/tex]
Solve for x
[tex]x = \frac{20}{5}[/tex]
[tex]x = 4[/tex]
Recall that:
[tex]y = 2 * x[/tex]
[tex]y = 2 * 4[/tex]
[tex]y = 8[/tex]
Recall that:
[tex]z = 6 + y[/tex]
[tex]z = 6 + 8[/tex]
[tex]z = 14[/tex]
Hence, the numbers are 4, 8 and 14
To test the result:
[tex]x + y + z = 26[/tex]
[tex]4 + 8 + 14 = 26[/tex]
[tex]26= 26[/tex]

Answer:
1/2
rise/run
rise = 1
run = 2
Step-by-step explanation:
Answer:
Slope = 1/2
Step-by-step explanation:
I would suggest that there are two ways you can find the slope to this problem.
1. You could start at where the line crosses the y-axis. You would then count using the rise/run formula. For example, in this situation, you would start at (0,1) since that's where the line crosses the y-axis. You go up one and go the right two times.
OR
2. You pick two points on the line and use the formula y2-y1/x2-x1. For example, we could pick the two points (0,1) and (2,2). We would plug in those numbers in the formula.
y2-y1/x2-x1 → 2-1/2-0 = 1/2

Is (1, 2) a solution of the system?
Answer:
Yes, the ordered pair (1, 2) is a solution to the system.
Step-by-step explanation:
The answer can be found quite quickly. Simply substitute the x coordinate of the given pair for x, and the y coordinate of the given pair for y.
The x coordinate is 1 and the y coordinate is 2, so...
3(1) - 4(2) = -5
2=4(1)-2.
Next, simplify:
3-8=-5
This equation is TRUE.
2=4-2
This equation is also TRUE.
Hopefully, this helps in some way!

7x-10 -5x +4 = 10 solve for x
Answer:
8
Step-by-step explanation:
7x - 5x = 2x
-10 + 4 = -6
2x - 6 = 10
+6 on both sides of =
2x = 16
divide by 2 on both sides of =
x = 8
Answer:
7x - 10 - 5x + 4 = 10
7x - 5x - 10 + 4 = 10
2x - 6 = 10
2x = 10 - 6
x = 4/2
x = 2

what is the sum of 2/5 and 3/4 what is the answer
Answer:
23/20 or 1 and 3/20
Step-by-step explanation:
Make sure they have the same common denominator. For 5 and 4, 20 would be the Least Common Denominator.
so 2/5=8/20 and 3/4=15/20
Add 8+15 and you get 23 so 23/20 you can leave it so or switch it to a mixed number 1 3/20

the sum of two numbers is 49.Twice the smaller number is 97 less than 3 times the larger number.What are the numbers. help mee I'm on homework and its due soon
Answer:
smaller number is 10
larger number is 39
Step-by-step explanation:
a = small number
b = larger number
a + b = 49
2a = 3b - 97
substitute 49-a into second equation for b
2a = 3(49-a) - 97
2a = 147 - 3a - 97
5a = 50
a = 10
b = 39

Answer:
First compute the perimeter of the first two windows: (3.4+5.2)*2=17.2
The perimeter of the four other windows: (3.6+4.8)*2=16.8
The total number of feet needed for the first two windows:
17.2*2 = 34.4 feet
The total number of feet needed for the four windows:
16.8*4 = 67.2 feet
The total number of feet needed is then: 34.4 + 67.2 = 101.6 feet.
