From the above expression we get,
=》x + y = 7 - [1]
=》3x - 2y = 11 - [2]
now, let's solve :
multiplying [1] by 3
=》3x + 3y = 21
=》 3x - 2y = 11
subtracting
now, subtracting [2] from [1]
=》3x + 3y - 3x + 2y = 21 - 11
=》5y = 10
=》y = 2
now, plugging the value of y as 2 in equation [1]
=》x + y = 7
=》x + 2 = 7
=》x = 5
So, value of :

Answer: 9 is A
Step-by-step explanation:
area of triangle= 1/2 bh
1/2 of 8 is 4
4x10= 40

A rectangle’s width is one-fourth of its length. Its area is 9 square units. The equation l(l) = 9 can be used to find l, the length of the rectangle.
What is the length of the rectangle?
0.75 units
1.5 units
3 units
6 units
Answer:
6 units
Step-by-step explanation:
The formula for the area of a rectangle = Length × Width
A rectangle’s width is one-fourth of its length.
W = 1/4 × L
W = L/4
Cross Multiply
L = 4W
A = 9 square units
Hence
9 = L × W
We substitute 4W for L
9 = 4W × W
9 = 4W²
We square root both side
√9 = √4W²
3 = 2W
W = 3/2
W = 1 1/2 unit or 1.5 units
Solving for L = Length
9 = L × W
9 = L × 1.5
L = 9/1.5
L = 6 units
Therefore, the Length of the rectangle = 6 units

A polar bear in a zoo weighs 3 times more than a baby elephant. Both of them together weigh 700 kilograms. How much does the polar bear weigh?
Answer:
525kg
Step-by-step explanation:
According to the scenario, computation of the given data are as follows,
Let weight = x
Then, Polar bear = 3x
Baby elephant = 1x
Total weight = 700kg
3x + 1x = 700 kg
4x = 700kg
x = 700 ÷ 4
= 175kg
By putting the value of x, we get
Polar bear weight = 3x = 3 × 175
= 525kg
Hence the weight of the polar bear is 525kg.

Solve for X
explain the process for this problem
Answer:
x = 40
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
126° is an exterior angle of the triangle, then
x + 2x + 6 = 126
3x + 6 = 126 ( subtract 6 from both sides )
3x = 120 ( divide both sides by 3 )
x = 40

GIVING BRAINLIST........
Answer:
36
Step-by-step explanation:
for the equation, we have to add 1 cubed, 2 cubed and 3 cubed together to get the answer. That equation would look like this
1^3 + 2^3 + 3^3
or expanded out
(1x1x1)+(2x2x2)+(3x3x3)
Solving that down, the equation turns into this
1 + 8 + 27
Adding those values together leaves us with 36!
Hope this helped, have a good rest of your day!
Answer:
36
Step-by-step explanation:
[tex]1^{3}[/tex] + [tex]2^{3}[/tex] +[tex]3^{3}[/tex] = 36
[tex]1^{3}[/tex] = 1 x 1 (= 1) x 1 = 1
[tex]2^{3}[/tex] = 2 x 2 (= 4) x 2 = 8
[tex]3^{3}[/tex] = 3 x 3 (= 9) x 3 = 27
27 + 8 + 1 = 36

Calculate the midpoint of the line segment with endpoints A(− 4, −5) and B(2, 3).
The midpoint of the line segment is (-1, -1).
What is midpoint of a line segment?The midpoint of a line segment is a point that lies halfway between 2 points. The midpoint is the same distance from each endpoint.
It is obtained by averaging the x-coordinates and averaging the y-coordinates of the endpoints of the segment.
Given endpoints
A(− 4, −5) and B(2, 3)
Midpoint of the line segment formula:
Midpoint of a Line Segment : Its x value is halfway between the two x values · Its y value is halfway between the two y values.
