Answer:
[tex]n=\frac{386x-75}{5}[/tex]
Step-by-step explanation:
Add like terms
[tex]-35x+3\cdot \frac{3}{5}x-22\cdot \:2x-15=n[/tex]
Add 15 on both sides
[tex]-35x+\frac{9}{5}x-44x-15+15=n+15[/tex]
Simplify
[tex]-35x+\frac{9}{5}x-44x=n+15[/tex]
Multiply sides by 5
[tex]-35x\cdot \:5+\frac{9}{5}x\cdot \:5-44x\cdot \:5=n\cdot \:5+15\cdot \:5[/tex]
Simplify
[tex]-386x=5n+75[/tex]
Divide both sides
[tex]\frac{-386x}{-386}=\frac{5n}{-386}+\frac{75}{-386}[/tex]
You will get
[tex]x=-\frac{5n+75}{386}[/tex]
Then you will solve for n using x
Multiply both sides by 386
[tex]\frac{386\left(5n+75\right)}{386}=386x[/tex]
Simplify
[tex]5n+75=386x[/tex]
Subtraction
[tex]5n+75-75=386x-75[/tex]
Simplify
[tex]5n=386x-75[/tex]
Divide by 5 to get n
[tex]\frac{5n}{5}=\frac{386x}{5}-\frac{75}{5}[/tex]
[tex]n=\frac{386x-75}{5}[/tex]
1. Kyle is using elimination to solve the system
below and will first add the equations together,
4x - 2y = 18

Which of the following shows the sum of the

a. 7X = 29
b. X=7
c. 7x = 7
d. X = -7
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]

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,

Step-by-step explanation:
If you add 300+50+2 you get 352 all you need to do is break down the number to pieces! :)
Explanation:
The number 352 has 3 in the hundreds place, 5 in the tens place, and 2 in the ones place.
So that's why 352 = 300 + 50 + 2
(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.

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)

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

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).

there are 124 more boys than girls
work out the total number of students at the school
b = boys
g = girls

[tex]b=11g/9[/tex]
Insert in the second equation
[tex]11g/9=g+124[/tex]

[tex]2g=124\cdot9\implies g=62\cdot9=\boxed{558}[/tex]
Solve for b
[tex]b=g+124=\boxed{682}[/tex]

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%
