Answer:
x = - 3.75
y = 28.75
Step-by-step explanation:
[tex] \begin{cases} x + y = 25\\\\ 5x + y = 10 \end{cases} [/tex]
Since, x + y = 25
Therefore, y = 25 - x..... (1)
5x + y = 10......(2)
Plug y = 25 - x in equation (2), we find:
5x + 25 - x = 10
5x - x = 10 - 25
4x = - 15
x = - 15/4
x = - 3.75
Plug x = - 3.75 in equation (1), we find:
y = 25 - (- 3.75)
y = 25 + 3.75
y = 28.75
(x, y) = (-3.75, 28.75)

Step-by-step explanation:
The question is incomplete. Let us use this as the complete version;
Of the people at a tennis club 2/5 are women. The rest of the people are men. What fraction of the people are men?
Let the total people be 1
Given
Fraction that are women = 2/5
Fraction that are men = 1 - 2/5
Fraction that are men = (5-2)/5
Fraction that are men = 3/5

richard klein works as auto mechanic and earns the following commission rates 3.00 percent for oil changes 5.00 percent for tune ups and 6.25 percent on auto parts sales he is guaranteed a minimum salary of $2,450.00 per month last month he brought in $2,500.00 in oil changes $4,500.00 in tune ups and sold $28,200.00 in parts what is his gross pay for the month
Answer:
Richard's gross pay for the month was $ 4,512.5.
Step-by-step explanation:
Given that Richard Klein works as auto mechanic and earns the following commission rates: 3.00 percent for oil changes, 5.00 percent for tune ups and 6.25 percent on auto parts sales; and he is guaranteed a minimum salary of $ 2,450.00 per month, if last month he brought in $ 2,500.00 in oil changes, $ 4,500.00 in tune ups and sold $ 28,200.00 in parts, to determine what is his gross pay for the month the following calculation must be performed:
2,450 + (2,500 x 0.03) + (4,500 x 0.05) + (28,200 x 0.0625) = X
2,450 + 75 + 225 + 1,762.5 = X
2,450 + 2,062.5 = X
4,512.5 = X
Thus, Richard's gross pay for the month was $ 4,512.5.

Find the equation of the line shown
Answer:
y = x+1
Step-by-step explanation:
Slope-intercept form
(y = mx+b)
m = slope and b = y-intercept
The line crosses the y-axis at (0, 1), therefore the y-intercept (b) = 1
The slope (m) = 1
Because the slope is 1, it does not need to be written in the equation, as any number multiplied by 1 is that number.

the diagram shows the distance between city P and city S and city T. which measurement is closest to x, than the distance between city P and city T in miles?
Answer:
1352 miles
Step-by-step explanation:
since city t, s, and P make a right angle we can use the Pythagorean theorem to find the hypotenuse (distance from t to p) 1180 squared=1,392,400 and 660 squared =435,600 so now we add them together and take its square root which is 1352.0
A bedroom door in the house has the same dimensions
as the front door, but the area of the base is 60 inches
rather than 72 inches. How much greater is the volume
of the front door than the bedroom door?
Answer:
12
Step-by-step explanation:
it will be 12 inches greater
The volume of the front door is 72 cubic inches greater than the volume of the bedroom door.
What is a rectangle?A rectangle is a 2-D shape with length and width.
The length and width are different.
If the length and width are not different then it is a square.
The area of a rectangle is given as:
Area = Length x width
We have,
Assuming that the bedroom door has the same height as the front door, we can use the formula for the volume of a rectangular solid to calculate the volume of each door.
Let L, W, and H be the length, width, and height of the front door, and let L' and W' be the length and width of the bedroom door.
We know that Lx W = 72 (since the area of the base is 72 square inches), and L' x W' = 60 (since the area of the base is 60 square inches).
The volume of the front door is given by V = LWH.
The volume of the bedroom door is given by V' = L'*W'*H.
Since the height is the same for both doors, we can divide V by V' to get the ratio of the volumes:
V/V' = (LWH)/(L'*W'H)
V/V' = (LW)/(L'*W') (canceling out the heights)
Substituting in the given values, we get:
V/V' = (72)/(60)
V/V' = 6/5
This means that the volume of the front door is 6/5 times the volume of the bedroom door.
To find the difference in volume, we can subtract the volume of the bedroom door from the volume of the front door:
V - V' = (6/5)*V' - V'
V - V' = (1/5)V'
V - V' = (1/5)(L'*W'*H)
Substituting in the values for L', W', and H, we get:
V - V' = (1/5)*(L' x W' x H)
V - V' = (1/5)(√(60) x √(60) x H)
V - V' = (1/5) x 360
V - V' = 72
Therefore,
The volume of the front door is 72 cubic inches greater than the volume of the bedroom door.
