It’s cost $3.75 to by 3/4 of a pound of walnuts.How many pounds of walnuts can your purchase with $11.25
Answer:
9/4 pounds of walnut
Step-by-step explanation:
First we divide 11.25/3.75=3 so we would know how many 3/4 pounds are there. Then, we know there are 3-3/4 pounds of walnuts. Mulitply them, you will get 9/4

1.Write the equation in point-slope form with the given slope of -2 and passes through the point (4,-5)
2. Write the equation in slope-intercept form of the line parallel to y=4x-2 and passes through (4,6)
3. Write the equation in slope-intercept form with the given slope of 3 and passes through (-1,1)
4. Write the equation in slope-intercept form of the line perpendicular to 2x-7y=1 and passes through (0,-4)
The equation in point-slope form: y - y₁ = m(x - x₁)
slope: m = -2
point: (4, -5) ⇒ x₁ = 4, y₁ = -5
Therefore, the equation of the line in point-slope form:
y + 5 = -2(x - 4)2.The equation in slope-intercept form: y = mx + b
Parallel lines has the same slope, so:
y = 4x + 2 ⇒ a = 4
If a line passes through the point (x₁, y₁) then the equation y₁ = mx₁ + b is true.
(4, 6) ⇒ x₁ = 4, y₁ = 6
So: 6 = 4·4 + b ⇒ b = -10
Therefore the equation:
y = 4x - 103.a = 3
(-1, 1) ⇒ x₁ = -1, y₁ = 1
So: 1 = 3·(-1) + b ⇒ b = 4
The equation:
y = 3x + 44.The product of slopes of perpendicular lines is -1.
2x - 7y = 1 ⇒ 7y = -2x + 1 ⇒ y = -²/₇x + ¹/₇
-²/₇×m = -1 ⇒ m = ⁷/₂
(0, -4) ⇒ x₁ = 0, y₁ = -4
-4 = ⁷/₂·0 + b ⇒ b = -4
The equation:
y = ⁷/₂x - 4y=[tex]x^{2}[/tex] +3x−10 Write this equation in factored form
Answer:
y = (x - 2) (x + 5)

Answer:
SI = 2052.61 ft
Step-by-step explanation:
cos 13 = 2000/SI
0.9744 = 2000/SI
multiply both sides by SI:
(SI)(0.9744) = 2000
divide both sides by 0.9744:
SI = 2052.61 ft

During the 2005 football season team tackle the team sack by eight points if the combine scores total of 26 find the individual team scores
Answer:
Team sack = 9
Team tackle = 17
Step-by-step explanation:
To start with, we'd assume that
Let x = the points scored by Team Sack
Let x + 8 = the points scored by Team Tackle
x + x + 8 = 26
So, go further and solve mathematically
2x + 8 = 26
if we subtract 8 from both sides, we have
2x = 18
Next, we then divide both sides by 2. So that,
x = 18/2
x = 9
Since we assumed the total points for Team Sack to be x, then Team Sack scored 9 points while Team Tackle scored x + 8 points, and that is 17

3(x - 6) = -15 + 3x
Yes no solution show work
Answer:
see explanation
Step-by-step explanation:
Given
3(x - 6) = - 15 + 3x ← distribute parenthesis on left side
3x - 18 = - 15 + 3x ( add 18 to both sides )
3x = 3 + 3x ( subtract 3x from both sides )
0 = 3 ← not possible
This indicates the equation has no solution
Kate sold a sailboat at a loss of 20%. If the selling price was $64, what was the original cost?
So she lost 20% of the original selling price.
$64 is 80% of the original price.
64/80=0.8
0.8·100=80 dollars. HOPE THIS HELPS!!!

A rectangular billboard is 9.35 meters wide and 6.82 meters tall. What is the perimeter of the billboard in meters?
Answer:
32.34 meters
Step-by-step explanation:
All you need to do is label the rectangle with the information given. 9.35 for width, and 6.82 for length.
Next, just fill in the other sides and add. Because it's a rectangle, then you should be able tp label the blank sides.
Next, just add all the sides together and then you'll get your perimeter!
9.35 + 9.35+ 6.82 + 6.82= 32.34

what is the expression of 14b
Answer:14 x b???
Step-by-step explanation:
A is the point with coordinates (4, 6)
B is the point with coordinates (d, 21)
The gradient of the line AB is three.
Work out the value of d.
The gradient is the slope.
Slope is the change in y over the change in x.
3 = (21-6) / (d-4)
Simplify:
3 = 15/(d-4)
(D-4) = 15/3
D-4 = 5
Add 4 to both sides :
D = 9

Hope this helps! Sorry if I am late.
Answer:
B
Step-by-step explanation:
For this problem, you would only need to figure one of them out since all the numbers vary. I calculated the mean. Mean is the same as the average. First, add all the numbers up. I got 112. Then, divide 112 by the amount of numbers you added (8). 112/8 is 14, and the mean=14 is b.

I am very poor at mathematics
Answer:
79
Step-by-step explanation:
Given the expression
x + 1/x = 9
Square both sides
(x + 1/x)^2 = 9^2
x^2 + 2x(1/x)+ (1/x)^2 = 81
x^2 + 2 + 1/x^2 = 81
x^2+1/x^2+2 = 81
x^2+1/x^2 = 81-2
x^2+1/x^2+ = 79
Hence the value of x^2+1/x^2 is 79

Step-by-step explanation:
A triangle has vertices at (1,10), (-5,2), and (7,2). What is its orthocenter. Show your work.
Answer:
Question: What is the orthocenter of a triangle with the vertices (-1,2) (5,2) and (2,1)?
The coordinates of point A are (-1,2), point B are (5,2), and point C are (2,1).
The orthocent is the intersection of the three altitudes. An altitude goes from a vertex and is perpendicular to the line containing the opposite side.
In the coordinate plane the equations of the altitudes can be found and then a system of equations can be solved.
Altitude 1. From point C perpendicular to the line containing side AB.
Slope of line AB is 0 (horizontal line), a vertical line is perpendicular to a horizontal line. Thus, the equation of altitude 1 is x=2 .
Altitude 2. From point B perpendicular to the line containing side AC.
Slope of line AC is −13 , the slope of a line perpendicular to line AC is 3. The equation of altitude 2 is y=3x−13
Altitude 3. From point A perpendicular to the line containing side BC.
Slope of line BC is 13 , the slope of a line perpendicular to line BC is −3 . The equation of altitude 3 is y=−3x−1
The orthocenter is the point where all three altitudes intersect.
x=2
y=3x−13
y=−3x−1
Use substitution to solve the first two equations y=3(2)−13=−7
The orthocenter is the point (2,−7)
we did not need the third equation, but we can use it as a check, plug the coordinates into the third equation:
−7=−3(2)−1
−7=−6−1
−7=−7 it works.
