Answer:
50
Step-by-step explanation:
There are 50 candies in the bag.
What is Algebra?A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them.
Variables are the name given to these symbols because they lack set values.
In order to determine the values, these symbols are also subjected to various addition, subtraction, multiplication, and division arithmetic operations.
Given:
John ate 40% of the candies in a bag.
If John ate 20 candies.
let the total number of Candies be x.
So, 40% of x = 20
40/ 100 x = 20
x = 2000/ 40
x= 50
Hence, there are total 50 Cadies.

Use the elimination method to solve the system of equations. Choose the correct ordered pair. 2y = x + 2 x - 3y= -5 O A. (2, 2) O B. (4,3) O C. (6,4) O D. (8,5)
Answer:
(4,3)
Step-by-step explanation:
2y = x + 2
x - 3y = -5
Rearrange the second equation to equal y.
x - 3y = -5
x + 5 = 3y
(x+5)/3 = y
Substitute into the first equation.
2y = x +2
2[(x+5)/3] = x + 2
(2x + 10)/3 = x + 2
2x + 10 = 3(x + 2)
2x + 10 = 3x + 6
10 - 6 = 3x - 2x
4 = x
Therefore, the correct ordered pair is (4,3) since x is equal to 4.

For the function F defined by F(x)=x2−2x+4, find F(−2).
Answer:
F(-2) = 12
Step-by-step explanation:
F(-2) = (-2)²- 2(-2) + 4
= 4 - (-4) + 4
= 4 + 4 + 4
= 12
The required value of function F(x) = x² − 2x + 4 at F( -2 ) is 12.
A quadratic function is given F(x) = x² − 2x + 4, value of the function is to be determined at x = -2.
What is a polynomial function?
A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
F(x) = x² − 2x + 4
Above given function is a quadratic function,
in order to find F(-2) , we have to put x = -2 in above given function.
F( -2 ) = ( -2 )² − 2( -2 ) + 4
F( -2 ) = 4 + 4 + 4
F( -2 ) = 16
Thus, the required value of function F(x) = x² − 2x + 4 at F( -2 ) is 12.

The measure of angle O from the given triangle is 9°.
Given that, m∠N=(5x-8)°, m∠O=(x-5)° and m∠P=(6x+1)°.
We need to find the measure of angle O.
What is the angle sum property of a triangle?Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.
Now, m∠N+m∠O+m∠P=180°
⇒ (5x-8)°+(x-5)°+(6x+1)°=180°
⇒ 5x+x+6x-8-5+1=180
⇒ 12x-12=180
⇒ 12x=192
⇒ x=192/12
⇒ x=16
So, m∠O = 16-5=9
Therefore, the measure of angle O from the given triangle is 9°.

What is the value of x?
Answer:
x = 7
Step-by-step explanation:
all triangles add up to 180
(90 from the right angle)
90 + (4x) + (5x +27) = 180
117 + 9x = 180
-117 - 117
9x = 63
x = 63/9
x = 7
Answer:
x = 7
Step-by-step explanation:
All triangles add up to 180, and (90 from the right angle)
90 + (4x) + (5x +27) = 180
117 + 9x = 180
-117 - 117
9x = 63
x = 63/9
Therefore, x = 7

Which function will have the steepest graph? O y=-2x O y=-* Oy = 3 x 2 2 Oy=
Answer:
Step-by-step explanation:
Y = 5/2x on edge
The steepest graph is given by y= 5/2x.
What is Slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the
change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx where, m is the slope
First, y= -2x
Here the slope is -2.
Second, y = -1/2 x
Here the slope is -1/2.
Third, y= 3/2x
Here the slope is 3/2 or 1.5
Fourth, y= 5/2x
Here the slope is 5/2 or 2.5
As, we know A steeper slope in a graph means that the rate of change is faster.
Then, y= 5/2x have steeper slopes.

which of the following is an important step in the formation of a fossil
a.) the organism must be a reptile
b.) the organism must be buried quickly
c.) the organism must die of natural cause
d.) the organism must not have any fur
Answer:
b
Step-by-step explanation:
After a bone, wood fragment, or shell is buried in sediment, it may be exposed to mineral-rich water that moves through the sediment. This water will deposit minerals into empty spaces, producing a fossil. Fossil dinosaur bones, petrified wood, and many marine fossils were formed by permineralization.
Answer: fossils can be formed only when a living thing is buried soon after it dies. If it is not buried soon enough, it decays. For this reason, most fossils are found in sedimentary rocks that were once under water.

What is the ratio of 3:6
Answer:
1:2
Step-by-step explanation:
You didn't really specify, but I'm going to assume you meant as simplified as possible. If you write it as a fraction, it will be ½ or as a decimal it will be 0.5.
Answer:
1:2
Step-by-step explanation:
Simplifying a ratio is like simplifying a fraction.
Simply put the number to the left as the numerator, and the number to the right as the denominator.
In this case, 3/6 = 1/2.
Hence, plug the numbers right back in and you get 1:2.

in the given figure ab parallel cd find the value of x
Step-by-step explanation: x = 73°
Draw PQ through E and parallel to AB, CD
Have x = ∠QED + ∠QEB
because PQ // CD => ∠QED = 50°
AB // PQ => ∠QEB + 157° = 180°
=> ∠QEB = 180 - 157 = 23°
=> x = 23° + 50° = 73°
( PQ is in the same direction as AB and CD )
angle efd = 130
180-50=130
angle ahe =23
180-157= 23
draw a imaginary line from h to f
this will create a triangle
now angle hfc = 90
90-50=40
now angle hfe =
90 - 23 = 67
therefore ,
x =
67+40+x=180
107 + x = 180
x = 180-107
x=73
