A collector has 2792 coins
altogether. Half of the coins
are on display. The collector
buys more coins at an auction
so that the coins on display
are now 40% of the collection.
How many coins are bought at
the auction?
Answer:
3490 coins
Step-by-step explanation:
Given data
Total coins= 2792 coins
Half of the coins are on display
that is 50% are on display
=2792/2
=1396
let the coins bought be x
40% of x= 1396
40/100*x= 1396
0.4x= 1396
x= 1396/0.4
x=3490
Hence 3490 coins were bought

The expression in the mathematical form will be 3x + 13.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Negative thirteen decreased by 3 times a number. Then the expression in the mathematical form is given as,
Let x be the number. Then the expression will be
⇒ 3x - (-13)
⇒ 3x + 13
The expression in the mathematical form will be 3x + 13.

$70.00 at 5% for 2 years
Answer:
$7
Step-by-step explanation:
Hey there
to solve this kind of problem we use the formula:
[tex]\frac{p * t * r}{100}[/tex] if we solve it :First, converting R percent to r a decimal
r = R/100 = 5%/100 = 0.05 per year,
then, solving our equation
I = 70 × 0.05 × 2 = 7
I = $ 7.00
The simple interest accumulated
on a principal of $ 70.00
at a rate of 5% per year
for 2 years is $ 7.00.

Prove that 327^3 + 173^3 is divisible by 500
It's a good question, and would like to see some answers
Answer:
327^3 = 34 965 783
173^3 = 5 177 717
34 965 783 + 5 177 717 = 40 143 500
40 143 500 ÷ 500 = 80 287
80 287 is a whole number, therefore, 327^3 + 173^3 is divisible by 500.
I hope this helps :)
Yes, the expression ( 327³ + 173³ ) is divisible by 500.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that the expression is 327³ + 173³ and is divided by 500. The division will be calculated as,
327³ = 34 965 783
173³ = 5 177 717
34,965,783 + 5,177,717 = 40,143,500
40,143,500 ÷ 500 = 80,287
80,287 is a whole number, therefore, 327³ + 173³ is divisible by 500.

Step-by-step explanation:
hope this helps
Answer:
51/20 or 2 11/20
Step-by-step explanation:
We know that percentages are fractions out of 100, so, our original fraction would be:
255/100
both of these numbers can be divided by 5, so:
255 ÷ 5 = 51
100 ÷ 5 = 20
51/20
This can also be turned into a mixed number, so:
2 11/20
n times 5 is equal to 24
word in equation and solve for variable
Step-by-step explanation: Remember that "times" mean multiply.
So reading the problem from left to right, we have n times 5,
that's n multiplied by 5 or 5n, is means equals, 24.
So we have 5n = 24.
We want to solve our equation for n so we want to get
n by itself on the left side of the equation.
Since n is being multiplied by 5, we need to divide both sides
of the equation by 5 and we have n = 24/5.
Don't be nervous to check your answer back in
the original equation even if it is a fraction.
