Answer:
Step-by-step explanation:
Pat's Potato farm grew 490 pounds of potatoes. If Pat delivered 3/7 of the potatoes to the vegi stand, it means that the number of pounds of potatoes that pat delivered to the vergi store is
3/7 × 490 = 210 pounds
The owner of the vegi stand delivered 2/3 of the potatoes he bought to the grocery store. It means that the amount delivered to the grocery store is
2/3 × 210 = 140
If half of the delivered potatoes was packaged in bags of 5 pounds each, it means that the amount of potatoes packaged in the bags is 140/2 = 70 pounds.
The number of bags of 5 pounds that the grocery store packaged is
70/5 = 14 bags
Which equation represents a quadratic relation?
a) y = 4x^2
b) y = 4x
c) y = 4x + 4
d) y = x^3
Answer:
a) y = 4x^2
Step-by-step explanation:
Because in a) y = 4x^2 the degree of equation is 2.
If y is directly proportional to x and y = 5 when x = 2, find the value of y when
x = 7
Answer:
I think that y=17.5 when x=7

Answer:
The answer is 6x^2+9x-15
Answer:
6x^2 + 9x -15x
Step-by-step explanation:
This may seem hard, but it is actually very simple.
When you think of area, you think of multiplying.
The equation for this rectangle is: 3(2x^2+3x-5)
Why is 3(2x^2+3x-5) the equation?
You are basically multiplying the height (3) and all the widths (2x^2, 3x, and -5)
3 x 2x^2 is 6x^2.
3 x 3x is 9x (3 x 3 = 9)
-5 x 3x is -15x (5 x 3 = 15, plus the negative sign)
Now, you will combine the answers and get 6x^2 + 9x -15x
Find the missing number___:7 = 12:21
A. 3
B. 4
C 14
D 12
Answer:
B. 4 would be your answer.
Step-by-step explanation:
7 x 3 = 21
4 x 3 = 12
:)
Answer:
B. 4.
Step-by-step explanation:
Let the number be x then
x/7 = 12/21
Crossmultiply:
x = 7*12 / 21
x = 12 / 3 = 4.

A population of 17500 has
5000 children under the age of 10. What is the fraction, in its simplest form, of children under 10?
Answer:
2/7
Step-by-step explanation:
Fraction of children under 10 = 5000 / 17500 (without being simplified).
we can then simplify it to:
50 / 175 = 10/35 = 2/7
Hope this helps.
Please mark brainiest
Answer:
[tex]\frac{2}{7}[/tex]
Step-by-step explanation:
So we know there is a population of 17,500 and 5000 are children under the age of 10. We want to find the the fraction of the children under 10 over the total population in it's simplest form so,
[tex]\frac{5000}{17500} =\frac{500}{1750} =\frac{50}{175}=\frac{2}{7}[/tex]
The length of a rectangle is two more than three times its width. If the perimeter of the rectangle is 60 m, find its length and width.
Answer:
The length and width of the rectangle are 23 m and 7 m respectively.
Step-by-step explanation:
P = 2L + 2W
P (perimeter of the rectangle) = 60 m
L (length of the rectangle) = 2 + 3W. W is the width of the rectangle
Therefore, L = 2 + 3W
P = 2L + 2W
60 = 2(2 + 3W) + 2W
60 = 4 + 6W + 2W
60 - 4 = 8W
56 = 8W
W = 56/8 = 7 m
L = 2 + 3W = 2 + 3(7) = 2 + 21 = 23 m
L = 23 m
W = 7 m
Micheal was asked to give examples of the identity property of addition and identity multiplication. Below are his answers.
Answer:
identity property of addition-
a+0=a
identity property of multiplication-
a*1=a
Step-by-step explanation:
i cant give u an exact answer as u didnt give Micheals answers so i just gave some examples about what addition and multiplication identity property should look like. Identity property's concept is to keep the same identity. Basically, "a" shouldnt change. In addition, to keep a the same all u hv to do is add 0 as anything plus 0 is the same. for multiplication, just multiply by 1. Hope this helps!!

please help me. how would you change x + 3y = 18 -3x -12y = -75 to eliminate y showing all of the work
Answer:
x = -3
y = 7
Step-by-step explanation:
x + 3y = 18
-3x - 12y = -75
multiply first equation by 4
4 × (x + 3y) = 18 ➡ 4x + 12y = 72
now add the two equations up
4x + 12y - 3x -12y = 72 - 75 (-12y will eliminate 12y)
x = -3

I really need help with this asap! thank you so much!
Answer:
Center → (1, -3)
Radius → 5 units
Step-by-step explanation:
Equation of the given circle is,
x² + y² - 2x + 6y - 15 = 0
Now convert this equation into the standard equation of the circle
x² - 2x + y² + 6y - 15 = 0
x² -2x + 1 - 1 + y² + 2(3)(y) + 9 - 9 - 15 = 0
(x² - 2x + 1) - 1 + (y² + 2(3y) + 9) - 9 - 15 = 0
(x - 1)² + (y + 3)² - 10 - 15 = 0
(x - 1)² + (y + 3)² = 25
(x - 1)² + (y + 3)² = 5²
By comparing this equation with the standard equation of the circle,
(x - h)²+ (y - k)² = r²
Where (h, k) is the center and r is the radius of the circle.
Center of the circle → (1, -3)
Radius of the circle → 5 units

What is the value of x in the equation ? 2.5(6x-4)=10+4(1.5+0.5x)
1/3
1/2
2
13
Answer:
x=2
Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x)
Distribute
15x -10 = 10 + 6 +2x
Combine like terms
15x -10 =16+2x
Subtract 2x
13x -10 = 16
Add 10
13x= 16+10
13x = 26
Divide by 13
13x/13 = 26/13
x =2
Answer:
x=2
Step-by-step explanation:
2.5(6x-4)=10+4(1.5+0.5x)
Distribute.
2.5*6x-2.5*4=10+4*1.5+4*0.5x
15x-10=10+6+2x
Combine like terms.
15x-10=16+2x
Add 10 to both sides
15x-10+10=16+10+2x
15x=26+2x
Subtract 2x from both sides.
15x-2x=26+2x-2x
13x=26
Divide both sides by 13

Which is the graph of g(x)?
Answer:
The last one
Step-by-step explanation:
Answer:
4 is the correct answer, I believe.
Reasoning:
The first line must be graphed with a constant y of 3, and stop before -2. Which it does on all 4 graphs.
The third line must, when extended, pass through point (0, -3). Only graph 1 and 4 follow that criteria, so it is not 2 or 3.
The second line's y-intercept must be 2, as well as begin at -2 and end before 2. Only graph 4 correctly plots this equation.
I hope this helps! :)
17. Segment MN is drawn in the coordinate plane. Point M has coordinates (13,9) and the midpoint of MN is the point (4.4). What are the
coordinates of point N?
(-9.4)
(-5, -1)
(1,3)
(8.5, 6.5)
The required coordinate of the point N is (-5, -1). Option b is correct.
Given that,
Segment MN is drawn in the coordinate plane. Point M has coordinates (13,9) and the midpoint of MN is the point (4.4). What are the coordinates of point N to be determined.
Coordinate, is represented as the values on the x - axis and y - axis of the graph
Let the coordinate of point N is (x, y).
Here, point M has coordinates (13,9) and the midpoint of MN is the point (4.4).
The Coordinate of the midpoint is given as,
(4 = (x + 13)/2, 4 = (y + 9 )/2)
(x = 8 - 13, y = 8 - 9)
(x = -5 , y = -1 )
Coordinate of point N is (x, y) = (-5, -1)
Thus, the required coordinate of the point N is (-5, -1).

What is the midpoint of the segment shown below ?
Answer:
The correct answer is a) (6, 3).
Step-by-step explanation:
The midpoint is determined in straight lines by subtracting the larger x-coordinate value and the smaller x-coordinate value. In this case, it is 10 - 2. You earn 8. Then, divide this answer by 2. So, you get 4. Finally, either subtract this from the larger x or the smaller x. You will earn 6. Since you are solving for a straight line, your y-coordinate will be the same as the others. Therefore, A is your answer.
The answer is (6,3)
