(Please help!!) Arnold is paid a graduated commission on sales. He earns 7% on sales up to $10,000 and 10% on sales over that amount. His goal is to make $2,500 next month. How much will he need to sell?
Answer:
Step-by-step explanation:
10000*7%= $700.00
2500-700=1800
1800 is 10% of 18,000
So 18,000 +10,000 = 28,000 in sales is needed to get $2,500 in commission.
What is the value of x that makes the statement true?
9x - 22 = 11x - 54
x =
Answer:
Step-by-step explanation:
9x-22=11x-54 take 9x from each side
-22=2x-54 add 54 to each side
32=2x divide by 2

What is the value of (–4) with an exponent of -3
Answer:
-64
Step-by-step explanation:
Because an exponent is basically a number repeated multiple times. So -4 x -4 x -4 would equal -64.
Solve this equation
2/3x−1/5x=x−1
Answer:
x=15/8
Step-by-step explanation:
Given: 2/3x-1/5x=x-1
Determine LCD: 10/15x-3/15x=x-1
Combine like terms: 7/15x=x-1
Get x on one side only: -8/15x=-1
Divide the coefficient on both sides: x=15/8
Anthony earned $131 in tips last night while working at the restaurant. If his tips consisted of $1 bills and $5 bills only and he counted 47 bills in total, then how many $5 bills did Anthony receive?
Answer:
21
Step-by-step explanation:
Let x = $1 bill
Let y = $5bill
Translating the word problem into an algebraic equation;
For the total number of bills;
[tex] x + y = 47[/tex] .........equation 1
For the total number of tips;
[tex] x + 5y = 131[/tex] ..........equation 2
*Solving the linear equation by using the substitution method*
Making x the subject in equation 1:
[tex] x = 47 - y[/tex] .......equation 3
Substituting "x" into equation 2;
[tex] (47 - y) + 5y = 131 [/tex]
Simplifying the equation, we have;
[tex] 47 + 4y = 131 [/tex]
[tex] 4y = 131 - 47 [/tex]
[tex] 4y = 84 [/tex]
[tex] y = \frac {84}{4} [/tex]
y = 21 (For the $5 bills).
Therefore, Anthony received 21 pieces of the $5 bills.
To find x;
Substituting "y" into equation 3;
[tex] x = 47 - 21[/tex]
x = 26 (For the $1 bill).
Which function translates each point on the graph of y=mx+b so that the slope of the segment from the original point to the translated point is 4/3?
g(x)=m(x+3)+b+4
s(x)=4/3x+b
t(x)=m(x−3)+b+4
h(x)=4/3mx+b
Function transformation involves changing the position of a function
The new function is:[tex]\mathbf{h(x) = \frac 43 mx + b}[/tex]
The function is given as:
[tex]\mathbf{y = mx +b}[/tex]
The ratio of the slopes of both segments is given as:
[tex]\mathbf{Ratio = \frac 43}[/tex]
Let the slope of the new segment be m2.
The slope of [tex]\mathbf{y = mx +b}[/tex] is m.
So, we have:
[tex]\mathbf{m_2 : m = \frac 43}[/tex]
Express as fractions
[tex]\mathbf{\frac{m_2 } m = \frac 43}[/tex]
Multiply both sides by m
[tex]\mathbf{m_2 = \frac 43m}[/tex]
From the list of given options,
[tex]\mathbf{h(x) = \frac 43 mx + b}[/tex] has a slope of [tex]\mathbf{m_2 = \frac 43m}[/tex]
Hence, the required function is:[tex]\mathbf{h(x) = \frac 43 mx + b}[/tex]

write your answer as a fraction or as a whole or mixed number 4 4/5 times 2 1/5
Answer:
It would be 10 14/25
Step-by-step explanation:
You could use a calculator for this, but that’d be cheating so let me explain.
We make both of our fractions improper first
4 4/5 = 24/5
2 1/5 = 11/5
We won’t need to change the “bottom number“ since they’re already the same, so let’s multiply them now.
24 x 11 = 264
————
5 x 5 = 24
Ten 24s can fit into 264 so our final number is

An online auction charges sellers a flat fee of $1.20 and 2% of the amount of the sale. Let A be the amount of the sale in dollars and C be the charge of the online auction. Explain whether the solutions A=−5 and C=1.1 are viable. (1 point)
A. The solutions are viable because the amount charged is positive.
B .The solutions are not viable because the amount of the sale cannot be negative.
C. The solutions are viable because the amount of the sale is an integer.
D. The solutions are not viable because the amount charged is not a whole number.
Answer:
B .The solutions are not viable because the amount of the sale cannot be negative.
Step-by-step explanation:
In this scenario, the calculations would make sense since the online auction charges a flat fee of $1.20 plus 2% of the amount of the sale. Since the sale is said to be -5 the 2% would be -0.1 therefore, making the total charge $1.1 which is what is given in the question. Unfortunately, -5 is not a viable value for the sale because if a sale is made it means that money was paid to the seller and that would only be a positive integer not a negative one. Thus, making this solution not viable.

The total number of students who could attend a field trip is represented by the variable t. The number of students in Group A is less than the number in Group B. Group A has 6 students more than 1 4 the total number of students, while Group B has 3 less than the total number of students. Which inequality represents this situation?
Answer:
Let's define:
A = # of students in group A
B = # of students in group B
C = # of students in group C.
"The total number of students who could attend a field trip is represented by the variable t."
This can be written as:
A + B + C = t.
"The number of students in Group A is less than the number in Group B."
Here we have a strictly "less than", then this is written as:
A < B.
"Group A has 6 students more than 1/4 the total number of students"
A = t/4 + 6
"Group B has 3 less than the total number of students"
B = t - 3.
Then we have the equations:
A + B + C = t.
A = t/4 + 6
B = t - 3.
A < B.
We could replace the second and third equatio in the fourth one, to get:
t/4 + 6 < t - 3.
t/4 + 9 < t
9 < t - t/4
9 < t*(4/4 - 1/4)
9 < t*(3/4)
(4/3)*9 < t
12 < t.
Then we found an inequality that defines the minimum possible value of t,

Answer:
Step-by-step explanation:
tan e = x/(4x-1)
tan f = (6x+5)/(12x + 31)
since tan e = tan f
x/(4x-1) = (6x+5)/(12x+31)
x(12x+31) = (4x-1)(6x+5)
12x^2 +31x = 24x^2 +20x -6x -5
31x = 12x^2 +14x -5
0 = 12x^2 -17x -5
0 = (12x -5)(x -1)

Suppose an artist is working on a painting. On Monday, he painted 1/2 of it. On Tuesday, he completed another 1/3 of the painting. What percent of the painting has yet to be done? Round your answer to the nearest whole percent.
Answer:
about 83%
Why:
1/3 + 1/2 = 0.83333333333
0.83333333333 as a percentage is 83.333333333%
Answer:
17%
Step-by-step explanation:
He completed 1/2 plus 1/3 of the painting.
The total he completed is
1/2 + 1/3 = 3/6 + 2/6 = 5/6
He needs to to 1 - 5/6 = 6/6 - 5/6 = 1/6 of the painting.
100% is the whole. He needs to do 1/6 of 100%.
1/6 * 100% = 100%/6 = 16.666...%
Answer: 17%
