There will be 7 nickels, 8 dimes, and 6 quarters of each type of coin. If there were one more dime than nickel and two more quarters than nickels.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
It is given that a newsboy has $2.65, consisting of nickels, dimes, and quarters
From the condition, the number of dimes exceeded the number of nickels by 1, and the number of quarters was equal to the number of nickels decreased by one.
Let the number of nickels, dimes, and quarters will be n, d, and q respectively.
1 × n = 5 cents
1 × d = 10 cents
1 × = 25 cent
d = n + 1
q = n – 1
As a result,
$2.65 ×100 = 265 cents.
The obtained equations are,
5n + 10d + 25q =265
d = n + 1
q = n – 1
Replace d with n + 1 and q with n - 1 in the equation
5n + 10× (n + 1) + 25 × (n - 1) = 265
5n + 10n + 10 + 25n - 25 = 265
40n -15 = 265
40n = 280
n = 280/40
n = 7 nickels
Substituting the value of n in the equation we get
d = 8 dimes
q = 6 quarters
n + d + q = 265 cents
35 cents + 80 cents + 150 cents = 265 cents
Convert the units from cents to dollars as
265 /100 = $2.65
Thus, there will be 7 nickels, 8 dimes, and 6 quarters of each type of coin. If there were one more dime than nickel and two more quarters than nickels

What is the value of the expression below when w = 8 and x = 4? 9w + 5x
Answer:
92
Step-by-step explanation:
If w=8 then you would multiply 9 by 8 which is 72. Then you would multiply 5 with 4 since x equals 4 which is 20. Then you would add 72+20 which gives you your answer which is 92
The value of expression 9w+ 5x when x=4 and w=8 is 92.
What is Expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
Expression: 9w + 5x
Now, put x= 4 and w= 8 we get
9w + 5x
= 9(8) + 5(4)
= 72 + 20
= 92.
Hence, the expression gives 92.

Answer:
The correct answer is B. -3.
Step-by-step explanation:
To solve this problem, we need to plug in -3 for all of the values of x in the equation. If we do this, we get:
f(x) = 2x + 3
f(-3) = 2(-3) + 3
Now, we can just simplify the expression found on the right side of the equation using PEMDAS. First, we should perform the multiplication.
f(-3) = -6 + 3
Next, we should add our final two terms together.
f(-3) = -3
Therefore, the correct answer is -3.

Aubrey, a pet store employee, wants to fit two fish tanks on one table. One fish tank is 1/6 of a foot wide and the other fish tank is 5/6 of a foot wide. When placed next to each other, what is the total width of the two fish tanks? Write your answer as a fraction or as a whole or mixed number.
Answer:
6/6 or one foot.
Step-by-step explanation:
If one of the fish tanks is 5/6 of a foot wide, and the other is 1/6, add them together.
5/6+1/6=6/6 or 1 foot wide. 6/6 means a whole number.
The total width of the two fish tanks as per the given relation is equal to 1 foot.
To find the total width of the two fish tanks when placed next to each other, add their widths.
The widths are given as fractions of a foot, so add them directly:
Width of the first fish tank = 1/6 foot
Width of the second fish tank = 5/6 foot
Total width of the two fish tanks = (1/6) + (5/6)
To add fractions, they need to have the same denominator.
Here, both fractions already have the same denominator (6),
So, simply add their numerators:
Total width = (1 + 5)/6
Total width = 6/6
Now, 6/6 is equal to 1.
Therefore, the total width of the two fish tanks is 1 foot.
