A rectangular vegetable patch has a perimeter of 36 meters and an area of 80 square meters. What are the dimensions of the vegetable patch?
Answer: 5 and 4
Step-by-step explanation:
Perimeter = 2 ( L + W)
18 = 2(L + W) divide through by 2
9 = L + W
9 - L = W
Area = L * W
20 = L (9 - L)
20 = 9L - L^2
L^2 - 9L + 20 = 0 factor
(L - 5) (L - 4) = 0
Set both factors to 0 and solve for L
L = 5 and L = 4

Anyone? Know how to do this
Answer:1=£34.2
2=£66.6
3=£9.18
4=£13,158
Step-by-step explanation:
We are decreasing the prices by 10%
1.£38
£38 = 100%
? =90%
90×38÷100=£34.2
2.£74
£74=100%
? = 90%
90×74÷100=£66.6
We are increasing the the salaries by 2%
1.£9
£9=100%
? =102
102×9÷100=£9.18
2.£12900
£12900=100%
? =102%
102×12900÷100=£13,158
Given m||n, find the value of x.
(9x-5)(6x+20)
Answer:
5/9 & -10/3
Step-by-step explanation:
Set each to 0 and solve:
9x-5 = 0
9x=5
x=5/9
6x+20=0
6x=-20
x=-20/6
x= -10/3 or -3 1/3
In the figure, since the line m and line n are parallel, the value of x is 25/3.
We have,
From the figure,
The two angles are corresponding angles since line m and line n are parallel.
Now,
9x - 5 = 6x + 20
Combine like terms on one side.
9x - 6x = 20 + 5
3x = 25
Divide 5 on both sides.
3x/3 = 25/3
x = 25/3
Thus,
The value of x in the given figure is 25/3.

Which expression represents how many donuts each student would get if the donuts were equally distributed and there were x
x
students in math club’s
Answer:
Number of donuts each student get = 144 / x
Step-by-step explanation:
Given:
Number of donuts = 12 dozen
Number of students = x
Find:
How many donuts each student get
Computation:
Total number of donuts = 12 × 12 = 144
Number of donuts each student get = Total number of donuts / Number of students
Number of donuts each student get = 144 / x

An investor purchased a house 8 years ago for $48,000 This year it was appraised at $73,500 Complete parts (a) through (d) below. (a) A linear equation V=mt+b,0
Answer:
b = $48000, m = $3187.5 / year
Step-by-step explanation:
The equation of a linear function is given as y = mx + b, where m is the rate of change, b is the value of y when x = 0, y = dependent variable and x = dependent variable.
Given that V = mt + b:
b = initial price of the house at 0 years = $48000
V = mt + 48000, At 8 years the house is appraised at $73,500
73500 = 8m + 48000
8m = 73500 - 48000
8m = 25500
m = 3187.5
