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

HELP HELP Point F is the midpoint of segment DE. DF = 2x+6 and DE = 2x+36. Find DE.
Answer:
since F is midpoint
DF= FE = 2x+6
DF +FE=DE
2x+6 + 2x+6 = 2x+36

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

Step-by-step explanation:
Steps for finding L.C.M of the given numbers :
[tex] \star[/tex] First of all find the prime factors of each numbers.
[tex] \star[/tex] Take out the common prime factors.
[tex] \star[/tex] Also take out the remaining prime factors.

Now,let's find the least common multiple ( L.C.M ) of 45 and 120 following those steps :
prime factors of 45 = 3 × 3 × 5
prime factors of 120 = 2 × 2 × 2 × 3 × 5
Common prime factors= 3 and 5

Answer:
Q7) ( 2,-2)
Q8) (- 0.5 , -2)
Step-by-step explanation:
As we have to find the mid-points of the line segments, the line segments will be divided in same ratio i.e. 1:1 (∵ A Mid-point divides a line segment into equal parts )
According to Section formula ,
[tex]( x' , y') = (\frac{mx^2 + nx^1}{m+n} , \frac{my^2+ny^1}{m+n} )[/tex]
where (m,n) are the ratios in which a line segment is divided & ( x¹ , y¹ ) ( x², y²) are the co-ordinates of a line segment.
In Q7 ,
x¹ = 3 , y¹ = -9 , x² = 1 , y² = 5 & m = n = 1
So putting the section formula here gives :-
[tex]( x' , y') = (\frac{1*1 + 1*3}{1+1} , \frac{1*5+1*(-9)}{1+1} ) = ( 2 , -2)[/tex]
In Q8 ,
x¹ = 5 , y¹ = -1 , x² = -6 , y² = -3
So putting the section formula here gives :-
[tex](x' , y') = (\frac{1*(-6) + 1*5}{1+1} , \frac{1*(-3) + 1*(-1)}{1+1}) = ( -0.5 , -2)[/tex]

what is the value of x ?
Step-by-step explanation:
2(2x - 6) + 2(x + 3) = 26
4x - 12 + 2x + 6 = 26
4x + 2x -12 + 6 = 26
6x - 6 = 26
6x = 26 + 6
6x = 32
x =32/6
x = 5.3333
Answer:
Step-by-step explanation:
2(2x -6) + 2(x + 3) = 26
4x - 12 + 2x + 6 = 26
6x - 6 = 26
6x = 32
x = 32/6= 16/3

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.

Identify the variable
Literary, variable means things that change in values;
Going by this definition, we have that:
3 -> This is not a variable because its value will always be 3
v -> This is a variable because its value can change once its value changes, the result of the expression will also change
- -> This is not a variable; it is an arithmetic operator to subtract
8 -> This is not a variable because its value will always be 8

Subtract the following fractions. (Reduce answers to lowest terms.)
3/10 - 1/4=
3/14
3/6
1/2
1/20
Answer:
1/20
Step-by-step explanation:
3/10 - 1/4
First, convert the fractions to a common denominator:
3/10 *2/2 = 6/20
1/4 * 5/5 = 5/20
Now put them back into the equation and solve:
6/20 - 5/20 = 1/20
Another way to do this:
3/10 - 1/4
Convert the fractions into decimals:
3/10 = 0.3
1/4 = 0.25
substitute back into the equation and solve:
0.3 - 0.25 = 0.05
convert back into fractions:
0.05 = 1/20
