Hope this helps ;) ❤❤❤
Answer:
-2n + 6
Step-by-step explanation:
Combine like terms (terms with the same amount of variables).
Note the laws of signs:
Two additions signs: If there are two addition signs directly next to each other (which will not be shown very much), it means to add.
One addition sign & One negative sign: If there is one of each signs directly next to each other (as shown here), you must default it to negative and subtract.
Two negative signs: If there are two negative signs directly next to each other, you must default it to positive and add.
First, change the expression to signify how you should combine the terms:
5n + 6 + (-7n) = 5n - 7n + 6
Combine like terms:
(5n - 7n) + 6
-2n + 6
-2n + 6 is your answer.

Answers
Answer:
-5
Step-by-step explanation:
Coordinate of A = -7
Coordinate if B = 5
Distance of AB = |-7 - 5| = |-12| = 12
We are asked to find the coordinate of the point that would be ⅙ from the A to B, which is ⅙ of AB.
Let's find what ⅙ of AB is.
AB = 12
Therefore, ⅙ of AB = ⅙*12 = 2.
From point A (-7), we move 2 points towards B which will give us ⅙ from A to B.
The coordinate = -7 + 2 = -5
-5 is the coordinate of the point with a fraction distance of ⅙ from A to B.

Answers
Answer:
Kindly check explanation
Step-by-step explanation: A ratio which compares a whole coin collection to a part of it would be expressed in such a way that, the numerator will be the part of the coin which is being compared and the denominator being the value of the entire coin. Mathematically, It could be expressed in proportion form as ;
(Part or amount of the coin which is being compared / total value of entire coin)
A / B such that;
A = value or amount of coin which is being compared.
B = value of the entire coin.
Or in the form
A : B
part of coin being compared : blue of entire coins
Laurie was completing the treasurer's report for her son's Boy Scout troop at the end of the school year. She didn't remember how many boys had paid the $24 full-year registration fee and how many had paid a $16 partial-year fee. She knew that the number of boys who paid for a full-year was ten more than the number who paid for a partial-year. If $400 was collected for all the registrations, how many boys had paid the full-year fee and how many had paid the partial-year
Answers
Answer:
14 boys paid for the full year fee and 4 boys paid for the partial year fee
Step-by-step explanation:
Create a system of equations, where x is the number that paid for the $24 fee and y is the number that paid for the $16 fee:
24x + 16y = 400
x = y + 10
Solve by substitution by plugging in y + 10 as x:
24x + 16y = 400
24(y + 10) + 16y = 400
Solve for y:
24y + 240 + 16y = 400
40y + 240 = 400
40y = 160
y = 4
Then, plug in 4 as y to find x:
x = y + 10
x = 4 + 10
x = 14
So, 14 boys paid for the full year fee and 4 boys paid for the partial year fee.

Apothem = (the answer is a sqaure root)
Answers
Answer:
[tex]\sqrt{20}[/tex]
Step-by-step explanation:
To find the Apothem of a shape, we need to find how long the distance is from a vertex to the center of the shape.
We can see that they've already showed us how to do it: We need to find the length of the hypotenuse of the red triangle.
To do this, we can use the Pythagorean Theorem, which states that [tex]a^2 + b^2 = c^2[/tex].
We know that a is going to be half of 4, which is 2. We also know that b is going to be 4, so we can substitute inside the equation.
[tex]2^2 + 4^2 = c^2\\\\4 + 16 = c^2\\\\20=c^2\\\\c=\sqrt{20}[/tex]

Which of the following lists has numbers arranged in INCREASING order?
Answers
Answer:
C
Step by step explanation:1/7 is greater than 1/8 so 1/7 must go after it. but negative is always less then positive so the correct order is
-1/8, -1/7, 1/8, 1/7
The numbers arranged in increasing order is
-1/8, -1/7, 1/8, 1/7
There are 4 values given:
1/7, 1/8, - 1/7, - 1/8
Negative figures are generally lesser than positive figures
1/7 is greater than 1/8
In negative values, the greater number becomes the smaller number
Therefore,
-1/8 is the the smaller number
Arrangements in increasing order =
-1/8, -1/7, 1/8, 1/7

A triangle has coordinates of A(1, 2), B(4, 6), and C(4, -3).
1. If the triangle is translated 2 units right, what are the new coordinates?
2. If ΔABC is reflected over the x-axis, what are the new coordinates?
Please show all work and not just the answer.
Answers
1 = (3,2) B= (6, 6) C = (6, -3)
Move two to the right since left and right deals with the x axis, add two to the x’s
2 = (1, -2) B = (4, -6) C = (4, 3)
Reflecting across the x axis means the formula is (x, -y) so switch the sign of the y’s
Answer:
1) A (3,2), B (6,6), C (6,-3)
2) A (1,-2), B (4,-6), C (4,3)
Step-by-step explanation:
1) Each of the x-values goes up two.
A (1,2) becomes (3,2)
B (4,6) becomes (6,6)
C (4,-3) becomes (6,-3)
2). I assume they mean the ORIGINAL ABC, not the one you just translated 2 units to the right.
To do this, you just multiply each y-value times negative one.
A (1,2) becomes (1,-2)
B (4,6) becomes (4,-6)
C (4,-3) becomes (4,3)

if 5 a solution of 3x + 30 = 9x?
Answers
Answer:
x = 5
Step-by-step explanation:
This equation can be rearranged in order to easily solve.
First, rearrange the equation by simply flipping it.
3x + 30 = 9x → 9x = 3x + 30
Then, you may solve for x.
9x = 3x + 30 subtract 3x from both sides of the equation
6x = 30 divide by 6 on both sides of the equation
x = 5

Step-by-step explanation:
30% solution = x 5% solution = ythen
10% solution = x + yAmount of acid:
0.3x + 0.05y = 0.1(x+y) 0.3x + 0.05y = 0.1x + 0.1y 0.2x = 0.05y 20x = 5y 4x = y x/y = 1/4So the ratio of 30% solution to the 5% solution is 1:4
