What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the number of boys in the class be = x
Let the number of girls in the class be = y
Now , the total number of students in the class = 60
So , the equation , will be
x + y = 60 be equation (1)
Now , the number of boys = 4 times the number of girls
So , the equation will be
x = 4y be equation (2)
Substitute the value of equation (2) in equation (1) , we get
4y + y = 60
On simplifying the equation , we get
5y = 60
Divide by 5 on both sides of the equation , we get
y = 12
So , the value of y is 12
Substitute , the value of y in equation (2) , we get
x = 4y
x = 4 x 12
x = 48
Therefore , the number of boys is 48 and the number of girls is 12
Hence , The number of boys in the class = 48 boys
The number of girls in the class = 12 girls

Find the measure of angle f given the information below.
Answer:
53 degrees
Step-by-step explanation:
This is a transversal question (look at attached). Because the lines are parallel, g will equal to 180(a straight line is 180 degrees) - a. Then, because g + f + e = 180 (since it is a straight line), substitute the values that we know and solve. (61) + f +(66) = 180. f = 53
Given various values of the linear functions f (x) and g(x in the table, determine the y-intercept of (f − g)(x).
x −6 −4 −1 3 4
f (x) 20 14 5 −7 −10
g(x) −36 −26 −11 9 14
(0, 4)
(0, −4)
(0, 8)
(0, −8)
The y-intercept of (f − g)(x) is 8. Therefore, option C is the correct answer.
Given various values of the linear functions f (x) and g(x) in the table.
What is a y-intercept?An intercept is a point on the y-axis, through which the slope of the line passes. It is the y-coordinate of a point where a straight line or a curve intersects the y-axis. This is represented when we write the equation for a line, y = mx+c, where m is slope and c is the y-intercept.
For the function f(x)
Here, (-6, 20) and (-4, 14)
Slope =(14-20)/(-4+6)
= -3
Substitute, m=-3 and (x, y)=(-6, 20) in y=mx+c, we get
20=-3(-6)+c
c=2
Substitute, m=-3 and c=2 in y=mx+c, we get
f(x)=-3x+2 --------(I)
For the function g(x)
Here, (-6, -36) and (-4, -26)
Slope =(-26+36)/(-4+6)
= 10/2 =5
Substitute, m=5 and (x, y)=(-6, -36) in y=mx+c, we get
-36=5(-6)+c
c=-6
Substitute, m=5 and c=-6 in y=mx+c, we get
g(x)=5x-6 --------(II)
Now, (f − g)(x)=-3x+2-(5x-6)
= -3x+2-5x+6
= -8x+8
Here, y-intercept is 8
The y-intercept of (f − g)(x) is 8. Therefore, option C is the correct answer.

Jovan is tired of measuring all the angles and sides to determine
if two triangles are similar. "There must be an easier way," he
thinks. "What if I know that all of the angles are congruent?
Does that mean that the triangles are similar?"
Answer:
yes congruent means identical of the same
Step-by-step explanation:
hope this helps
Answer: The answer is here
Step-by-step explanation:
If the two sides of a triangle are in the same proportion of the two sides of another triangle, and the angle inscribed by the two sides in both the triangle are equal, then two triangles are said to be similar. Thus, if ∠A = ∠X and AB/XY = AC/XZ then ΔABC ~ΔXYZ.
If the measures of the corresponding sides of two triangles are proportional then the triangles are similar. Likewise if the measures of two sides in one triangle are proportional to the corresponding sides in another triangle and the including angles are congruent then the triangles are similar.
after 3 days a sample of radon-222 has decayed to 58% of its original amount. (a) what is the half-life of radon-222? (b) how long will it take the sample to deca
The half-life of radon-222 is 3 days, it will take an additional 3 days for the remaining 42% of the sample to decay, for a total of 6 days for the sample to decay completely.
What is half life of an element?The half-life of a radioactive is time for 50% of its particles to decay or disintegrate into a new element. The pace at which a radioactive material will decay is predicted using this indicator of an isotope's stability. An element's half-life, which differs substantially across various elements, is based on the unique characteristics of its nucleus.
For instance, the half-life of uranium-238 is 4.5 billion years whereas that of carbon-14 is 5,730 years. This indicates that half of the carbon-14 atoms in a sample will have decayed after 5,730 years, and half of the uranium-238 atoms will have decayed after 4.5 billion years.
How to solve?
(a) After 3 days, the sample has decayed to 58% of its original amount, which means that half of the original amount has already decayed. Therefore, the half-life of radon-222 is 3 days.
(b) Since the half-life of radon-222 is 3 days, it will take an additional 3 days for the remaining 42% of the sample to decay, for a total of 6 days for the sample to decay completely.

The number of years for the value of $900 to reach $1,800 if the rate of interest is 4%, is 25 years.
What is interest?When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.
Given:
The amount after some years, A = $1800,
The rate of interest, r = 4% per annum,
The principal amount, p = $900,
Calculate the number of years as shown below,
A = P + SI
1800 = 900 + p × r × t / 100
Here, t is the time in years,
1800 - 900 = 900 × 4 × t / 100
900 = 3600t / 100
900 = 36t
t = 900 / 36

what is the circumference of a circle with a diameter of 58 inches
Answer:
58π or about 182.12
Step-by-step explanation:
In order to find circumference with diameter, you need to use the formula:
C = πd
Multiply the diameter (58) by pi, and since pi is an irrational number, let's use 3.14.
3.14(58) = 182.12
58π would be the answer as well if you don't multiply pi.

What is fraction?
A fraction, which derives from the Latin word fractus, which means "broken," is a portion of a whole or, more broadly, any number of equal parts. A fraction, such as one-half, eight-fifths, or three-quarters, indicates how many parts of a particular size there are when spoken of in everyday English. A common, vulgar, as well as simple fraction is one that has a non-zero denominator displayed below (or after) the line that separates the numerator from the denominator. Compound fractions, complex fractions, as well as mixed numeral fractions are examples of uncommon fractions that use numerators and denominators.
Main Body:
Let the fraction be a/b
In First condition
b = a + 2(1)
In Second condition
a + 1/b + 1 = 4/5
5(a + 1) = 4(b + 1)
5a + 5 = 4b + 4
5a - 4b = 4 - 5
5a - 4b = -1
Using 1
5a - 4(a + 2) = -1
5a - 4a - 8 = -1
a = 8 - 1
a = 7
Now,
Using 1
b = a + 2
b = 7 + 2
b = 9
Fraction = a/b = 7/9
