Write the equation. Six more than twice a number is 16.
Answer:

Step-by-step explanation:
Since two times an unknown number plus 6 equals 16, the equation would be 16=6+2x
A newsboy has $2.65, consisting of nickels, dimes and quarters.
If 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, what was the number of each kind of coin?
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

2/9 of the members are boys in a community service club. if there are 95 more girls than boys, how many girls are there in club?
Answer:
133 girls
Step-by-step explanation:
Total members = x
Number of boys = [tex]\frac{2}{9}x[/tex]
Number of girls = [tex]\frac{2}{9}x +95[/tex]
Number of boys + Number of girls = total members
[tex]\frac{2}{9}x+\frac{2}{9}x+95=x\\\\\frac{2}{9}x+\frac{2}{9}x=x -95\\\\\frac{2}{9}x+\frac{2}{9}x-x=-95\\\\\frac{4}{9}x-x = -95\\\\\frac{4}{9}x-\frac{9}{9}x = -95\\\\\frac{-5}{9}x=-95\\\\x = -95*\frac{9}{-5}\\\\x=19*9[/tex]
x = 171
Number of boys = [tex]\frac{2}{9}*171[/tex] = 2 * 19 = 38
Number of girls = 38 + 95 = 133

Find the equation of the line through point (−1,4) and parallel to 5x+y=4
Answer:
3y-5x=none
Step-by-step explanation:
Solve the literal equation for y.
2x+5y = 3y+8
Answer:
y = -x +4
Step-by-step explanation:
2x+5y = 3y+8
Subtract 3y from each side
2x+5y-3y = 3y-3y+8
2x+2y = 8
Subtract 2x from each side
2x+2y -2x = -2x+8
2y = -2x+8
Divide by 2
2y/2 = -2x/2 +8/2
y = -x +4

Nathaniel's car used 10 gallons to travel 360 miles. How far can he travel on 16 gallons?
Answer:
576 miles per 16 gallons
Step-by-step explanation:
Step 1:
360 ÷ 10
Step 2:
36 miles per gallon
Step 3:
36 × 16
Answer:
576 miles per 16 gallons
Hope This Helps :)
Answer:
Nathaniel can travel 576 miles on 16 gallons.
Explanation:
Knowing that 10 gallons would be enough for 360 miles, we can divide 360 by 10 to get the amount of miles that can be driven for only ONE gallon.
360 divided by 10 is 36, so 36 is the amount of miles driven for one gallon. Now we can multiply 36 by 16 to get the amount for 16 gallons. 36 multiplied by 16 is 576. Nathaniel can travel 576 miles on 16 gallons.
Which statement best describes the equation x5 + x3 – 14 = 0?
The equation is quadratic in form because it is a fifth-degree polynomial.
The equation is quadratic in form because the difference of the exponent of the lead term and the exponent of the middle term is 2.
The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.
The equation is not quadratic in form because the exponent of the lead term is not the square of the exponent of the middle term.
Answer:
2.The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.
Step-by-step explanation:
A quadratic equation is any equation that can be rearranged in standard form as :
ax² + bx + c = 0
Where a, b and c are coefficients and a ≠ 0.
Since for a quadratic equation, the power of x is a non negative integer, it is considered as a polynomial. A quadratic equation is a second-degree polynomial (i.e the gratest power of x is two).
The equation is not a quadratic equation because it cannot be rewritten as a second-degree polynomial.
We want to see which statement describes the equation x^5 + x^3 - 14 = 0.
The correct option is:
The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.
First, our equation:
x^5 + x^3 - 14 = 0.
Is a polynomial of degree 5 (the degree is equal to the maximum exponent).
Thus, this is not a quadratic equation.
Where a quadratic equation is a polynomial of degree 2.
Notice that we also can't replace x by another variable, such that it becomes a quadratic equation, then the correct statement is:
The equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.

Is the number 7.787887888... a rational number ?
Answer: No, it is not rational (it is irrational)
If we had something like 7.78787878... where the "78"s go on forever, then it would be rational. This is called a repeating decimal.
Something like 7.787887888... does not have a repeating pattern. It has 7's and 8's, but the number of 8's seems to increase by 1 each time you list a 7. So this is why the given number is not rational.
Paul,Linda,and Aaron make homemade cards. Paul can make 1 card for every 3 cards Linda makes. Linda can make 3 cards for every 2 cards that Aaron makes. During the week,Aaron makes 72 cards. How many more cards does Linda make than Paul during the week?
Answer:
Linda makes 72 more cards than Paul
during the week
Step-by-step explanation:
Here, we want to know how many cards Linda makes than Paul during the week.
We proceed as follows;
From the question;
If Paul makes 1 card, then Linda has made three
Now let’s get their relationship with Aaron;
If Aaron makes 2 cards , Linda has made three
Now since Aaron made 72 cards, Let’s say Linda has made x cards
Let’s get the value of x now
To get the value of x, we simply cross multiply;
2 - 3
72 - x
2 * x = 3 * 72
x = (3 * 72)/2 = 108 cards
Now recall , for every 3 cards of Linda, Paul made only 1;
So the number of cards Paul will make if Linda makes 108 will be 108/3 = 36
So the number of more cards that Linda makes than Paul during the week will be ; 108 -36 = 72 cards

Given:
Number of white roses = 4
Number of red roses = 8
To find:
The ratio of the number of red roses to the number of white roses.
Solution:
Using the given information, the ratio of the number of red roses to the number of white roses is
[tex]\text{Required ratio}=\dfrac{\text{Number of red roses}}{\text{Number of white roses}}[/tex]
[tex]\text{Required ratio}=\dfrac{8}{4}[/tex]
