John has $5.05 in quarters and nickels in his pocket. If John only has 25 coins in his pocket, how many of the coins are quarters?
Answer:
Step-by-step explanation:
q+n=25
n=25-q
25q+5n=505, using n=25-q in this equation gives you
25q+5(25-q)=505
25q+125-5q=505
20q+125=505
20q=380
q=19
So 19 of the coins are quarters.
Answer:
John has 19 quarters out of 25 coins.

Jenny is 9 years younger than Sammie. Five years ago Sammie was 4 times older than Jennie. How old is each now?
Pls Help Need Answer By 7:00.
Jenny is 8 years old and Sammie 17 is years old.
Given that:Jenny is 9 years younger than Sammie.Five years ago, Sammie was 4 times older than Jennie.To find:Current age of Jennie and Sammie
Calculation and Explanation.Let the current age of Jennie be x.
Let the current age of Sammie be y.
Then from given data we have:
[tex]x = y-9\\4(x-5) = (y-5)[/tex]
We'll substitute value of x from equation 1 in equation 2:
[tex]4(y-9-5) = (y-5)\\3y = 51\\y=17[/tex]
Thus, from equation 1 and y = 17, we have:
[tex]x=y-9\\x=17-9\\x=8[/tex]
Thus, Jenny is 8 years old and Sammie 17 is years old.

k+ 6 ≥ 19, if k = 11
Answer:
Then it would be the other way around 19 ≥ k + 6
Wait for more responses if needed.
The given Inequality is correct when 19 ≥ k + 6.
What is inequality?Inequality compares "two values, showing if one is less than, greater than, or simply not equal to another one".
Given k + 6 ≥ 19 if k = 11
11 + 6 ≥ 19 substitute k = 11
17 ≥ 19 here Inequality is False.
Hence, 19 ≥ k + 6.

There are 24 children at the skate park. Seven of them are on bikes, nine of
them are on skateboards, and the rest are on inline skates (4 wheels per
skate). How many wheels are at the skate park?
Answer:
82 wheels
Step-by-step explanation:
7(2) + 9(4) + 8(4) = x
14 + 36 + 32 = x
82 = x
Answer:
114
Step-by-step explanation:
9 + 7 = 16
24 - 16 = 8 students on inline skates
8 x 4 wheels per skate = 32
32 x 2 shoes per person = 64
7 x 2 wheels per bike = 14
9 x 4 wheels per skate board = 36
36 + 14 + 64 = 114

A school hall costs £200 to hire.
Parents get a 10% discount.
30 parents share the cost equally.
How much does each parent pay
Answer:
£6
Step-by-step explanation:
The computation of the each parent pay is shown below;
But before that the cost of hall after considering the discount is
= £200 - 10% of £200
= £200 - £20
= £180
Now there are 30 parents
So each parent pay is
= £180 ÷ 30 parents
= £6
Two times the smaller of two consecutive even integers is 18 more than the larger.
Answer:
2x = x+1 + 18
---
x = 19
-----------
x+1 = 20
Step-by-step explanation:
The smaller of the two consecutive even integers is 20, and the larger is 22.
What is a number system?A numeral system is a way of writing numbers; it's a way of mathematically notating a collection of numbers by utilizing a consistent set of digits or other symbols.
Let's call the smaller of the two consecutive even integers "x".
Since the integers are consecutive and even, we know that the larger integer must be 2 more than the smaller integer. Therefore, we can represent the larger integer as "x + 2".
According to the problem statement, two times the smaller integer (2x) is 18 more than the larger integer (x + 2). We can express this algebraically as:
2x = x + 2 + 18
Simplifying this equation, we can combine like terms on the right-hand side:
2x = x + 20
Subtracting x from both sides, we get:
x = 20
Therefore, the smaller of the two consecutive even integers is 20, and the larger is 22 (since 20 + 2 = 22).

A triangle has sides with lengths of 10, 15, and 6 feet. Find the perimeter of a similar triangle whose shortest side is 7
Answer:
P = 36 1/6 feet
Step-by-step explanation:
you can create the following proportion:
6 / 7 = 10 / x
cross-multiply:
6x = 70
x = 11 2/3
use the same ratio to write a second proportion to find the last side:
6 / 7 = 15 / x
cross-multiply:
6x = 105
x = 17 1/2
Perimeter = 7 + 11 2/3 + 17 1/2 = 28 7/6 + 7 = 29 1/6 + 7 = 36 1/6 feet

One side = 18
Bottom side = 18 (equalateral triangle)
we can use phytagorues theorum:
a = the altitude (unknown)
b= one side (half of the bottom side) = 18/2 = 9
c = hypothenus = 18 (given)
a^2 + b^2 = c^2
a^2 + 9^2 = 18^2
a^2 = 18^2 - 9^2

Answer:
x + (4x-6) • 2
Step-by-step explanation:
First, let's start by calling the width of the rectangle x
Because the length is 4 times the width minus 6, the equation for length will be 4x-6
The width and length together will be x + (4x-6)
You then have to times it by 2 to find the whole perimiter.

What is the equation of the line that passes through the point (−7,−1) and has a slope of 11?
Answer:
y = 11x + 76Step-by-step explanation:
The equation of a line with a slope of "a" and containing a given point (x₀, y₀) is:
y - y₀ = a(x - x₀)
a = 11, x₀ = -7, y₀ = -1
So:
y - (-1) = 11(x - (-7))
y = 11x + 77 - 1
y = 11x + 76
