2x+y+2z=7, 2x-y+2z=1, 5x+y+5z=13
Answers
Answer:
y = 3
x = 2 - z
Step-by-step explanation:
We have the system:
2*x+y+2*z=7
2*x-y+2*z=1
5*x+y+5*z=13
In the first and second equations we have the term (2*x + 2*z) = A
Then we can rewrite the first two equations as:
A + y = 7
A - y = 1
isolating A in the first equation, we get:
A = 1 + y
Now we replace this in the other equation:
(1 + y) + y = 7
1 + 2*y = 7
2*y = 6
y = 3.
then:
A + y = 7
A + 3 = 7
A = 7- 3 = 4
A = 2*x + 2*z = 4.
Now let's go to the third equation:
(5*x + 5*z) + y = 13
we can rewrite the thing inside the parentheses as:
(5/2)*(2*x + 2*y) + y = 13
And we know that:
2*x + 2*z = 4
y = 3
then this can be written as:
(5/2)*(4) + 3 = 5*2 + 3 = 13
Then we can conclude that:
y = 3
2*z + 2*x = 4
2*(z + x) = 4
(z + x) = 4/2 = 2
x = 2 - z
Notice that the solution is not only a point, we have infinite solutions for this problem.

Find the coordinates of P so that P partitions segment A to B in the ratio 5:1 with A(2,
4) and B(8, 10).
Answers
Answer:
Point P has coordinates (7,9) (last choice)
Step-by-step explanation:
We are given the endpoints A(2,4) B(8,10) and the point P lying on the segment AB with the condition that P partitions it in the ratio 5:1.
This means the distances AP, PB and AB follow the conditions:
[tex]\frac{AP}{PB}=\frac{5}{1}[/tex]
AP+PB=AB
We can work with each coordinate separately. Suppose P has coordinates (x,y), thus:
[tex]x-x_a=5(x_b-x)[/tex]
[tex]x-x_a=5x_b-5x[/tex]
Adding 5x and subtracting:
[tex]6x=5x_b+x_a[/tex]
Dividing by 6:
[tex]\displaystyle x=\frac{5x_b+x_a}{6}[/tex]
Substituting:
[tex]\displaystyle x=\frac{5*8+2}{6}=\frac{42}{6}=7[/tex]
x=7
Now for the y-axis:
[tex]\displaystyle y=\frac{5y_b+y_a}{6}[/tex]
Substituting:
[tex]\displaystyle y=\frac{5*10+4}{6}=\frac{54}{6}=9[/tex]
y=9
Point P has coordinates (7,9) (last choice)

In winter, the price of apples suddenly went up by $0.75 per pound. Sam bought 3 pounds of apples at the
new price for a total of $5.88.
Answers
Answer:
original price per pound = $1.21
Step-by-step explanation:
In winter, the price of apples suddenly went up by $0.75 per pound. Sam bought 3 pounds of apples at the new price for a total of 5.88
write an equation to determine the original price per pound (p)
find the original price per pound
Let
p = original price per pound
3p = original price for 3 pounds
Additional increase = 0.75
Number of pounds = 3
3p + 0.75(3) = 5.88
3p + 2.25 = 5.88
3p = 5.88 - 2.25
3p = 3.63
p = 3.63/3
p = 1.21
original price per pound = $1.21
