Alex has 84 quarters and nickels worth a total of $17.80. Which equation can be used to find q, the number of quarters Alex has? 0.25q + 0.05(q – 84) = 17.80 0.05q + 0.25(84 – q) = 17.80 0.25(q – 84) + 0.05q = 17.80 0.05(84 – q) + 0.25q = 17.80
Answers
Answer:
D
Step-by-step explanation:
The equation can be used to find q is 0.05(84 - q) + 0.25q = 17.80 option (D) 0.05(84 - q) + 0.25q = 17.80 is correct.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
We have:
Alex has 84 quarters and nickels worth a total of $17.80.
As we know,
1 nickel = 5 cents
1 dime = 10 cents
1 quarter = 25 cents
1 dollar = 100 cents
The amount that Alex = 84 quarters + $17.80
q = 84 quarters + $17.80
q is the number of quarters Alex has.
Remaining nickel value = 84 - q
In cents:
= 0.05(84 - q)
q in cents:
= 0.25q
0.05(84 - q) + 0.25q = 17.80
Thus, the equation can be used to find q is 0.05(84 - q) + 0.25q = 17.80 option (D) 0.05(84 - q) + 0.25q = 17.80 is correct.

Let f(x)=-3x and g(x) = 2x-1
Find the following: 4g(x) - f(x)
Answers
Answer:
11x-4
Step-by-step explanation:
f(x)=-3x
g(x) = 2x-1
4g(x) - f(x)
4(2x-1) - ( -3x)
Distribute
8x -4 +3x
Combine like terms
11x-4
Here, we are provided with two polynomials f(x) and g(x),and we need to find 4g(x) - f(x).
Given,
f(x) = -3xg(x) = 2x - 1Now,we need to find 4g(x) - f(x). We will simply substitute the given value of polynomials to get the answer.
[tex]4g(x) - f(x)[/tex]
[tex]4(2x - 1) - ( - 3x)[/tex]
Opening the parentheses,
[tex]8x - 4 + 3x[/tex]
Now combing the like terms, and adding them,
[tex]8x + 3x - 4[/tex]
[tex] \boxed{11x - 4}[/tex]
This is our final result.

******************************************************************************
Kate buys 10 tickets to a show. She also pays a $5 parking fee. She spent $35 to see the show.
Each ticket costs x.
10 tickets cost 10x.
Parking is $5.
Total is $35
10x + 5 = 35
******************************************************************************
Ram has 35 gel pens. He gives an equal number of pens to each of his 5 friends and has 10 pens left for himself.
The number of pens he gives each friend is x.
The total number he gives is 5x.
He started with 35 pens ands ended up with 10 pens.
35 - 5x = 10
5x + 10 = 35
******************************************************************************
Yin spends 10 hours on homework this week. She spends 5 hours on science homework and then answers 35 math problems.
Total time spent on homework is 10 hours.
Science homework is 5 hours.

Step-by-step explanation:
-4.5x -2y = -12.5 -------(1)
3.25x -y = -0.75 --------(2)
From (2) we can make y the subject of the relation
y = 0.75+3.25x -------(3)
Input 0.75+3.25x into y in (1)
-4.5x -2(0.75+3.25x) = -12.5
-4.5x -1.5- 6.5x = -12.5
-4.5x -6.5x -1.5 = -12.5
-11x = -12.5 +1.5
-11x = -11
x = 11/11
x = 1
If x = 1,substitute 1 into x in (3)
y = 0.75+3.25x
y = 0.75 +3.25(1)
y = 0.75 +3.25
y = 4
x = 1,y = 4
Given the original statement "If a number is negative, the additive inverse is positive,” which are true? Select three options.If p = a number is negative and q = the additive inverse is positive, the original statement is p → q.
If p = a number is negative and q = the additive inverse is positive, the inverse of the original statement is ~p → ~q.
If p = a number is negative and q = the additive inverse is positive, the converse of the original statement is ~q → ~p.
If q = a number is negative and p = the additive inverse is positive, the contrapositive of the original statement is ~p → ~q.
If q = a number is negative and p = the additive inverse is positive, the converse of the original statement is q → p.
