In an on-line survey, a school learns that 77 of 100 parents prefer to receive the newsletter electronically. How many paper newsletters would the school estimate are needed if there are 650 parents?
The number of paper newsletters the school needed is given by the equation A = 149.5
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 paper newsletters the school needed be A
Now , the equation will be
The percentage of parents who prefers newsletters electronically = 77 %
So , percentage of parents who prefers paper newsletters = 100 % - 77 %
The percentage of parents who prefers paper newsletters = 23 %
The total number of parents = 650
So , the number of paper newsletters the school A = percentage of parents who prefers paper newsletters x total number of parents
Substituting the values in the equation , we get
The number of paper newsletters the school A = ( 23/100 ) x 650
The number of paper newsletters the school A = 149.5
Therefore , the value of A is 149.5
Hence , the equation is A = 149.5

A linear function has a y-intercept of -12 and a slooe of 3/2. What is the equation of the line?
how to slove liner equation?
for example: 3×−2=−7
Answer:
x = -5/3
Step-by-step explanation:
3x - 2 = -7
Add 2 to both sides
3x - 2 + 2 = -7 +2
3x = -5
Divide both sides by 3
3x/3 = -5/3
x = -5/3

Answer:
A) In 4 hours the tempature would both be the same
B) The tempature then would be 3 degreees Fahrenheit
Step-by-step explanation:
SO for the first step just make a list
In my format
x (hour): Coldspit and Frostberg in temperature
1st hour: -4.5 and 15
2nd hour: -2 and 11
3rd hour: 0.5 and 7
4th hour: 3 and 3
Answer:
after 52/3 hours
temparature will be at -151/3
Step-by-step explanation:
y = -2.5x - 7
y = -4x + 19
-2.5x - 7 = -4x + 19
4x - 2.5x = 19 + 7
1.5x = 26
1.5x = 26
3/2x = 26/1
2/3 x 3/2x = 26/1 x 2/3
x = 52/3
y = -4x + 19
y = -4(52/3) + 19
y = -208/3 + 19
y = -208/3 + 19/1
y = -208/3 + 57/3
y = -151/3

if f(x)=3x-2 find f-1 (13)
Answer:
Firstly
f(x)=3x-2=y then
Interchanging x and y we get
x=3y-2
x+2=3y
y=(x+2)/3
f-1(x)=(x+2)/3
f-1(13)=(13+2)/3
f-1(13)=5
A function is defined as a relation between a set of inputs having one output each.
The inverse of function f(x) = 3x - 2 is:
y = (x+2)/3
What is a function?A function is defined as a relation between a set of inputs having one output each.
The inputs are called the domain of the function.
The outputs are called the range of the function.
We have,
f(x) = 3x - 2
The inverse of f(x):
step 1:
Put f(x) = y
y = 3x - 2
step 2:
switch x and y
x = 3y - 2
step 3:
solve for y
x = 3y - 2
x + 2 = 3y
y = (x+2)/3
Thus,
The inverse of f(x) = 3x - 2 is y = (x+2)/3

A fruit company delivers its fruit in two types of boxes: large and small. Delivery of 4 large boxes and 8 small boxes has a total weight of 105 kilograms. Delivery of 2 large boxes and 3 small boxes has a total weight of 46 kilograms. How much does each type of box weigh?
Answer:
x = 13.25 kg
y = 6.5 kg
Step-by-step explanation:
Let
Large box = x
Small box = y
4x + 8y = 105 (1)
2x + 3y = 46 (2)
(Multiply (2) by 2 to eliminate x
2x + 3y = 46 (2) ×2
4x + 6y = 92 (3)
4x + 8y = 105 (1)
Subtract (3) from (1)
8y - 6y = 105 - 92
2y = 13
y = 13/2
y = 6.5kg
Substitute y = 6.5 into (2)
2x + 3y = 46 (2)
2x + 3(6.5) = 46
2x + 19.5 = 46
2x = 46 - 19.5
2x = 26.5
x = 26.5/2
x = 13.25 kg
Trey has 75 in his saving account. Each month he deposits 25 into the account. Which expression shows the amount of money that Trey deposits in 3 months.
Answer: 75 + 25(3)
Step-by-step explanation:
From the question, we are informed that Trey has 75 in his saving account and that each month he deposits 25 into the account.
The expression that shows the amount of money that Trey deposits in 3 months would be:
= 75 + 25m
where, m = number of months
= 75 + 25(3)
= 75 + 75
= 150

write an expression with a constant of -4 and a coeffiecient of 2
Answer:
2x^2 - 4
Step-by-step explanation:
- A "constant" in an equation is a number that stands alone, with no attached variable or exponents.
- A "coefficient" is a number placed before a variable that is multiplying with the variable. For example, 2 would be the coefficient of 2xy, because it is the number you are multiplying "xy" by.
