Step-by-step explanation:
If n represents a number then write an expression for two less than one fourth of n
Answer: [tex]\frac{1}{4}n-2[/tex]
This is the same as [tex]\frac{n}{4} - 2[/tex] and it is also equivalent to [tex]0.25n-2[/tex]
=====================================================
Explanation:
n is some placeholder for a number
one fourth of that number is [tex]\frac{1}{4}n[/tex] which is the same as [tex]\frac{n}{4}[/tex] or [tex]0.25n[/tex] since 1/4 = 0.25
From here, we subtract off 2 to get [tex]\frac{1}{4}n-2[/tex] as one possible final answer.

-3x+8y=73
X-7y=-46
Answer:
Step-by-step explanation:
Let's solve for x.
−3x+8y=73
Step 1: Add -8y to both sides.
−3x+8y+−8y=73+−8y
−3x=−8y+73
Step 2: Divide both sides by -3.

Milk creamery charges $2 for a cup of ice cream and $0.75 for each topping (t) . Justin wants a cup of ice cream with for toppings
Answer:
$5
Step-by-step explanation:
$2 for cup
$0.75 per topping
4 toppings $0.75 a piece
4 × .75 = 3.00
$2 + $3 = $5
The expression which represents the given situation is 2+0.75x and the ice cream cost Justin is $5.
Given that, Milk Creamery charges $2 for a cup of ice cream and $0.75 for each topping (t).
We need to find which expression best represents the situation, and how much will the ice cream cost Justin.
What is an expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between. The mathematical operators can be addition, subtraction, multiplication, or division.
Now, the expression for the given situation is 2+0.75x
Justin wants a cup of ice cream with four toppings, so the cost of ice cream=2+0.75(4)=$5
Therefore, the expression which represents the given situation is 2+0.75x and the ice cream cost Justin is $5.

You are saving to buy a new phone you have $150 in your bank account and can save $55 each week assuming you don’t spend any money write an expression to represent the amount of money you will have in your bank account after W weeks
Answer:
150+55w
Step-by-step explanation:
150+55w
150 never changes
(55)(w), 55 changes depending on number of weeks
Answer:
The expression is: 150 + 55W
Step-by-step explanation:
amount already in your a/c = $150
Amount saved per week = $55
Number of weeks to save for is W
Amount saved in W weeks is $55W
Total amount saved in W weeks is $150 + $55W
Ignoring the symbols, the expression is 150+55W

pqrs is a rectangle with sides ps=5cm and pq =12cm find the length of qr ,sr and the two diagonals pr and qs.
tell the answer
PQRS is a rectangle.
PS = 5cm
PQ = 12cm
To Find:The length of qr ,sr and the two diagonals pr and qs.
Solution:Opposite sides of a rectangle are equal.
QR = PS = 5cm
SR = PQ = 12cm
By using Pythagoras Theorem, we get
PR = √PS^2 + SR^2
or, PR = √25 + 144
or, PR = √169
or, PR = 13cm
Diagonals of a rectangle are equal.
QS = PR = 13cm
Answer:QR = 5 cm
SR = 12 cm
PR = 13 cm
QS = 13 cm
7x − 14 = 7(x − 2)
please help ❤️
Answer:
Infinite Solutions
Step-by-step explanation:
Let's solve this equation my simplifying it so that we have x on one side.
Apply the distributive property on the right side:
[tex]7x - 14 = (7\cdot x) + (7\cdot -2)\\\\7x-14 = 7x-14[/tex]
Woah, that's strange. We have the exact same thing on both sides of the equation. This means there are infinite solutions. If we tried simplifying this, we'd just end up with 0 = 0.
Test it out! Any value of [tex]x[/tex] will work for this equation.

A.
Since the digit in the hundredths place is less than 5, keep the digit in the hundredths place. Then drop the digit in the thousandths place.
B.
Since the digit in the hundredths place is less than 5, keep the digit in the tenths place. Then drop the digit in the hundredths and thousandths places.
C.
Since the digit in the thousandths place is greater than or equal to 5, increase the digit in the hundredths place by 1. Then drop the digit in the thousandths place.
D.
Since the digit in the thousandths place is greater than or equal to 5, keep the digit in the hundredths place. Then drop the digit in the thousandths place.
Answer: 212.81
C. Since the digit in the thousandths place is greater than or equal to 5, increase the digit in the hundredths place by 1. Then drop the digit in the thousandths place
Step-by-step explanation:
What is 212.809 rounded to the nearest hundredth?
When we want to round off 212.809 to the nearest hundredth, the main thing that we will need to consider is for us to look at the thousandths value that is contained in the number of 212.809, and this is is 9.
Since 9 is more than 5, iteams that we will have to add 1 to the number at the hundredth place. This.meane we will add 1 to 0 which will give us 1 and we them drop the digit in the thousandths place. Therefore,
212.809 = 212.81 to nearest hundredths
A file that is 242 megabytes is being downloaded. If the download is 17.1% complete, how many megabytes have been downloaded? Round your answer to the nearest tenth.
Answer:
4.1 megabytes
Step-by-step explanation:
well we use the rule of three
242 megabytes ------- 100%
x megabytes -------- 17.1%
(x megabytes)(100%)=(242 megabytes)(17.1%)
[tex]x=\frac{242*17.1}{100} \\\\x=\frac{4138.2}{100} \\\\x=4.1382\\\\x=4.1[/tex]

The three steps of the problem solving process are
x = 7 + 3y
5x + 6y = 14
Which ordered pair (x,y) is the solution to the system of equations above?
x = 7 + 3y
or, x - 3y - 7 = 0 ........ (i)
5x + 6y = 14
or, 5x + 6y - 14 = 0 .........(ii)
To Find:The value of x and y.
Solution:By dividing eq. ii by 2, we get
5/2x + 3y - 7 = 0 ........ (iii)
By adding eq. i and eq. iii, we get
15/2x = 0
or, x = 0 ........(iv)
By putting eq.(iv) in eq. (i), we get
0 - 3y - 7 = 0
or, -3y = 7
or, y = -7/3
Answer: ( 0, -7/3 )The value of x and y is 0 and -7/3 respectively.

Estimate the number of school-aged children in the city where the population is approximately 60,000, if 1 of every 10 citizens is a school-aged child. If 500 children can attend each school, about how many schools will the city need?
1 out of 10 are school aged.
Divide total population by 10:
60,000 / 10 = 6,000 are school aged.
Each school holds 500, divide school aged by 500:
6,000 / 500 = 12
They would need 12 schools.
The number of schools the city with the population 60,000 requires are 12.
Given that, the number of school-aged children in the city where the population is approximately 60,000.
In population 1 out of 10 are school aged.
Divide total population by 10
60,000/10 = 6,000 are school aged
Each school have 500 children, so the number of schools are
6,000/500 = 12
Therefore, the number of schools the city needs are 12.
