THE ANSWER IS
?????
36
Answer:
27 is 75% of 36Step-by-step explanation:
METHOD 1:
[tex]\begin{array}{ccc}27&-&75\%\\\\x&-&100\%\end{array}\qquad|\text{cross multiply}[/tex]
[tex](75)(x)=(27)(100)\\\\75x=2700\qquad|\text{divide both sides by 75}\\\\x=36[/tex]
METHOD 2:
[tex]n[/tex]-a number
[tex]p\%=\dfrac{p}{100}\\\\75\%=\dfrac{75}{100}=0.75[/tex]
75% of a number is 27:
[tex]0.75\cdot n=27\qquad|\text{divide both sides by 0.75}\\\\n=36[/tex]

Which first step for solving the given system using substitution results in an equation without fractions
3x + y = 9
5x-3y=1
Slove for x in the first equation
Solve for y in the first equation
Solve for x in the second equation
Solve for y in the second equation
Answer:
Solve for x in the second equation.
Step-by-step explanation:
Subtract 3x from both sides and you can substitute y in the second equation for the first equation and solve for x.
Solving for x in the second equation is the first step in solving the given system using substitution resulting in an equation without fractions. Option B is correct.
What is the system of two equations?A set of two linear equations with two variables is called a system of linear equations. They create a system of linear equations when evaluated collectively.
The given equation in the problem is;
Equation 1: 3x + y = 9
Equation 2: 5x-3y=1
Equation 1;
3x + y = 9
y=9-3x
Equation 2:
5x-3y=1
5x+3(9-3x)=1
5x+27-9x=1
-4x=-26
x =6.5
Hence, solving for x in the second equation is the first step in solving the given system using substitution resulting in an equation without fractions.
Hence, option B is correct.

Step-by-step explanation:
Kimberly is deciding between two cell phone plans. The first plan has a $50 sign-up
fee and costs $20 per month. The second plan has a $30 sign-up fee and costs $25 per
month. After how many months will the costs be the same for the two phone plans?
Answer:
2month and 2 weeks
Step-by-step explanation:
We are told that the first plan has a $50 sign-up
fee and costs $20 per month.
let the number of months be x, and the total cost be y
y=20x+50---------1
The second plan has a $30 sign-up fee and costs $25 per
let the number of months be x, and the total cost be y
y=30x+25---------2
Equate the two equations we have
20x+50=30x+25
solve for x, collect like terms
50-25=30x-20x
25=10x
divide both sides by 10
x= 25/10
x=2.5 months
x= 2month and 2 weeks
How many solutions does 8p + 1 = 4p +2 have?
Step-by-step explanation:
8p + 1 = 4p + 2
8p - 4p = 2 - 1
4p=1
4p/4p=1/4p
p=0.25
The equation 8p + 1 = 4p + 2 have one solution which is p = 0.25.
What is an Equation?Equations are mathematical statements where we write two expressions which is equal to each other. There will be a left hand side and a right hand side on either sides of an equation.
The main classes of equations in algebra are linear equations and polynomial equations. On these include quadratic equations, cubic equations, differential equations and so on.
We have the expressions 8p + 1 and 4p + 1 equal to each other.
8p + 1 = 4p + 2
Subtracting the term 4p on both sides, we get,
8p + 1 - 4p = 4p + 2 - 4p
4p + 1 = 2
Subtracting both sides with 1,we get,
4p + 1 - 1 = 2 - 1
4p = 1
Dividing both sides by 4, we get,
p = 1/4
p = 0.25
Hence there is one solution to the equation 8p + 1 = 4p + 2 which is p = 0.25.

in a carton, 3 out of 10 glasses are cracked. what percent of glasses are not cracked?
Answer:
70%
Step-by-step explanation:
[tex]\frac{3}{10}[/tex] = [tex]\frac{30}{100}[/tex] = 30%
100 - 30 = 70
Answer:
70% are not cracked
Step-by-step explanation:
So 10 = 100%
So each bottle equals 10%
If 3 glasses are cracked it would be 30% cracked
So subtract 30 from 100 and you get 70%

What is system of equations?The equation in mathematics is the relationship between the variables and the number and establishes the relationship between two or more variables.
A finite set of equations for which common solutions are sought is referred to in mathematics as a set of simultaneous equations, often known as a system of equations or an equation system.
Given equations are 2x+4y=16 and 4x+8y=−16. The equations will be solved as below,
2x+4y=16
4x+8y=−16
Multiply the first equation by 2 and solve,
4x+8y=16
4x+8y=−16
Therefore, Craig multiplies 2x + 4y = 16 by 2 and then subtracts the equations. He finds the result is a contradiction, so there is no solution. The correct option is B.

What is a function?
A function is defined as the expression that set up the relationship between the dependent variable and independent variable. The collection of possible inputs into a function, or the set of input values for which the function is defined, is known as the domain of the function.
The natural numbers are 1, 2, 3, and 4......
f(x) = x - 3 gives
f(1) = 1 - 3 = -2
f(2) = 2-3 = -1
