Answer:
x=6
Step-by-step explanation:
10-5x=3(x-4)-2(x+7)
Distribute
10-5x=3x-12-2x14
Combine like terms
10-5x = x-26
add 5x to each side
10-5x+5x = x+5x-26
10 = 6x-26
Add 26 to each side
10+26 = 6x-26+26
36 = 6x
Divide by 6
36/6 = 6x/6
6 =x
Answer:
[tex]10-5x=3\left(x-4\right)-2\left(x+7\right)[/tex]
[tex]3\left(x-4\right)-2\left(x+7\right)[/tex]
combine like terms:-
[tex]=3x-12-2x-14[/tex]
[tex]3x-2x=x[/tex]
[tex]=x-12-14[/tex]
Subtract -12 -14
[tex]=x-26[/tex]
[tex]10-5x=x-26[/tex]
Subtract 10 from both sides:-
[tex]-5x=x-36[/tex]
Now, subtract x from both sides:-
[tex]-5x-x=x-36-x[/tex]
[tex]-6x=-36[/tex]
Divide both sides by -6:-
[tex]\frac{-6x}{-6}=\frac{-36}{-6}[/tex]
[tex]x=6[/tex]

A contractor, Susan Meyer, has to haul gravel to three building sites. She can purchase as much as 18 tons at a gravel pit in the north of the city and 14 tons at one in the south. She needs 10, 5, and 10 tons at sites 1, 2, and 3, respectively. The purchase price per ton at each gravel pit and the hauling cost per ton are given in the table below. Susan wishes to determine how much to haul from each pit to each site to minimize the total cost for purchasing and hauling gravel. Pit Hauling cost per Ton at Site Price per ton Site 1 Site 2 Site 3 North $30 $60 $50 $100 South $60 $30 $40 $120 Now suppose that trucks (and their drivers) need to be hired to do the hauling, where each truck can only be used to haul gravel from a single pit to a single site. Each truck can haul 5 tons, and the cost per truck is five times the hauling cost per ton given above. Only full trucks would be used to supply each site.
Required:
Formulate this problem as a transportation problem with two sources and three destinations.

Step-by-step explanation:
use the formula to solve for volume
a rectangular plot has 17m length and 14m width. What will be the cost of fencing at a rate of Rs.25 per meter
The fence would be the perimeter of the shape.
Perimeter = 17 + 17 + 14 + 14 = 62 meters.
Multiply the price per meter by total meters:
25 x 62 = 1550
For fencing , we have to find the perimeter of rectangle.
[tex] \large\begin{gathered} {\underline{\boxed{ \rm {\red{Formula \: \: Using \: = \: 2 \: ( \: L + B \: )}}}}}\end{gathered}[/tex]
L denotes length of rectangleB denotes breadth of rectangleL = 17 mB = 14 mSubstuting the valuesPerimeter of rectangle = 2 ( L + B )
Perimeter of rectangle = 2 ( 17 m + 14 m )
Perimeter of rectangle = 2 ( 31 m )
Perimeter of rectangle = 62 m.
Hence, the perimeter of rectangle is 62 m.
For Fencing Cost = perimeter × rate of fencing per metre
Fencing Cost = 62 × 25
Fencing cost = 1,550
Hence, the cost of fencing of a rectangular plot is 1,550

4x+2y=5 , 2x-3y=13 pair of equations to two decimal places of accuracy.
Answer:
x = 2.56, y = -2.63
Step-by-step explanation:
I first multiplied the second equation by two, getting
4x-6y = 26
I then subtracted the equations
4x+2y = 5
- 4x-6y = 26
--------------------
8y = -21
y = -2.63
with y solved, I plugged it into the second equation to get x:
2x-3(-2.63) = 13
2x+ 7.89 = 13
2x = 5.11
x = 2.56

Answer:
minimum: 2 at x=0maximum: 10 at x=10Step-by-step explanation:
When looking for extremes, one must consider both the turning points and the ends of the interval. Here, there is a relative minimum at x=7, and a relative maximum at x=3. However, the values at the ends of the interval are more extreme than these.
The absolute minimum on the interval is 2 at x=0.
The absolute maximum on the interval is 10 at x=10.

French; 9
Both; 7
Step-by-step explanation:
28 - 19 = 9, therefore there are only 9 students who can only speak French
28 - 16 = 12, therefore there are only 12 students who can only speak English
12 + 9 = 21, then subtract 21 from the 28 total students
28 - 21 = 7, therefore there are only 7 students who can speak both

Write the equation of the line shown in the graph above in slope intercept form
A) y=2/3x+1
B) y=-x+2/3
C) y=-2/3x+1
D) 2x+3y=3
Answer:
C, y=-2/3x+1
Step-by-step explanation:
using points (0, 1) and (3, -1) obtained from the graph:
slope = -1-1/3-0 = -2/3
use one of the points above lets take (1, 0) and another point (x,y)
slope = y-0/x-1 = -2/3
y=-2/3x+1

Which regular polygon has a rotation of 240 degree to carry the polygon onto itself?
Equilateral triangle
Octagon
Rectangle
Pentagon
The regular polygon that has a rotation of 240 degrees to carry the polygon onto itself is an B. Octagon.
What is an Octagon?This refers to an eight-sided polygon that has eight angles and is used in geometry.
Hence, we can see that an octagon, can be rotated to 240 degrees and when this is done, it is able to carry itself which cannot be done by others as other polygons would need 360 degrees to carry themselves.

How do I answer this
Answer:
11. Yes
12. No
Step-by-step explanation:
11. The x values only have 1 y value, so it makes it a function.
12. The x value 0 has 2 y values -4 and 4, therefore it is not a function, because in functions that x value can only have one y value,

Answer:
10·2^-8 grams
Step-by-step explanation:
The each day, the initial amount for that day is multiplied by 1/2. After 8 days, the initial amount has been multiplied by (1/2)^8, where the exponent of 8 signifies that (1/2) is a factor 8 times in the product.
After n days, the quantity remaining is ...
q(n) = 10·(1/2)^n = 10·2^(-n)
after 8 days the remaining amount is ...
q(8) = 10·2^-8 . . . grams
