A jar contains n nickels and d dimes. There is a total of 206 coins in the jar. The value of the coins is $13.95. How many nickels and how many dimes are in the jar?
Answer:
73 dimes and 133 nickels
Step-by-step explanation:
$13.95 = 1395 cents
5n + 10d = 1395 (since each nickel is 5 cents and each dime is 10 cents)
5n = 1395 - 10d (subtract 10d from both sides to solve for n)
n = 279 - 2d
n + d = 206
279 - 2d + d = 206 (substitute n with the previous expression)
279 - d = 206 (add variable d and -2d)
-d = -73 (solve for d and divide both sides by negative 1)
d = 73
n + 73 = 206 (solve for n and subtract both sides by 73)
n = 133

Mya and her three friends bought 7 1/5 pounds of cherry sours at 1.30 per pound. If the cost of cherry sours id divided evenly among the 4 friends, how much will each person pay
Answer: Each person will pay $2.34.
Step-by-step explanation:
Given: Cost of one pound of cherries = $1.30
Cost of [tex]7\dfrac15[/tex] pounds of cherries = [tex]7\dfrac15\times 1.30[/tex]
[tex]=\dfrac{36}{5}\times1.30[/tex]
= $9.36
Each person will pay = (Cost of [tex]7\dfrac15[/tex] pounds ) ÷ 4
[tex]=9.36\div4[/tex]
=$2.34
Hence, Each person will pay $2.34.

Lauren went shopping for a new pair of pants because of a sale. The price on the tag
was $20, but Lauren paid $13 before tax. Find the percent discount.
Answer:
discount rate= 0.35
Step-by-step explanation:
Giving the following information:
The price on the tag was $20, but Lauren paid $13 before tax.
To calculate the discount rate, we need to use the following formula:
Total discount= total price * ( 1 - discount rate)
13= 20 * (1 - discount rate)
13= 20 - 20discount rate
20discount rate = 7
discount rate= 7 / 20
discount rate= 0.35

Answer:
3, 50, 2
Step-by-step explanation:
By multiplying all terms by 5, we are trying to remove the fraction on the left hand side. On the right hand side of the equation, expand the bracket by multiplying 5 to each term in the bracket.
3(n +25)= 5(10) +5([tex] \frac{2}{5} n[/tex])
3(n +25)= 50 +2n
To find the value of n, expand the bracket on the left hand side:
3(n) +3(25)= 50 +2n
3n +75= 50 +2n
Bring all n terms to one side, constants to the other:
3n -2n= 50 -75
n= -25

The solution set to this inequality solution set = ∅.
How to solve inequality equations?
An inequality is a mathematical expression using the symbols >, <, ≥, and ≤. Many straightforward inequalities can be resolved by adding, taking away, multiplying, or dividing both sides until the variable is all that remains. On multiplying or dividing both sides with negative number changes the direction of inequality. If we flip the number, we just have to flip the inequality symbol also.
Inequality:
2x-3> 2x-5/2
2x - 2x > -5/2 + 3
2x - 2x > -2.5 + 3
0 > -2.5 + 3
0 > 0.5
This shows that solution set will not contain any elements, i.e. x ∈ ∅
Therefore, Solution set = ∅

Write an exponential function in the form y=ab^xy=ab x that goes through points (0, 11)(0,11) and (3, 3773)(3,3773).
Answer:
y = 11(7)^x
Step-by-step explanation:
The exponent equation that goes through points (0, 11) and (3, 3773) will be y = 11 · (7)ˣ.
What is an exponent?Let a be the initial value and x be the power of the exponent function and b be the increasing factor.
The exponent is given as
y = a(b)ˣ
The equation passes through (0, 11) and (3, 3773). Then the equation will be given as,
ab⁰ = 11
a = 11
Then the other equation is given as,
ab³ = 3773
11 b³ = 3773
b³ = 343
b³ = 7³
b = 7
Then the exponent equation that goes through points (0, 11) and (3, 3773) will be y = 11 · (7)ˣ.
