Write and solve an equation for the following:

Step-by-step explanation:

15 = 6 + 2(n-3) + 3n

or, 15 = 6 + 2n - 6 + 3n

or, 15 = 6 - 6 + 2n + 3n

or, 15 = 0 + 5n

or, 15 = 5n

or, 15/5 = n

or, 3 = n

;- n = 3.....

standard form is placing all terms in decreasing exponent order

Answer:

it is a polynomial because all of the exponents are non-negative

If two lines intersect, then there is only one solution - where they cross.

Looking at the graph, we can see the intersection point of these two lines.

The intersection point is (1,1) - one unit to the right of the origin and one unit up.

Hope this helps! :)

Answer:

Xander has 140 friends

Kennedy has 92 friends

Step-by-step explanation:

Let x represent # of friends Xander has at the start

Let x+11 represent # of friends Kennedy has at the start

Let 2(x+11) rep. the final # of friends Kennedy has

Let 4x rep. the final # of friends Xander has

Total = 232

So we just need to solve for x:

2(x+11) + 4x = 232

2x + 22 + 4x = 232

6x = 210

x = 35             < - This means that xander started with 4 friends.

Sub x to find friends for each:

4x = ?

4(35) = 140 friends

2(x+11) = ?

2(35+11) = 92

Answer:

d = 7

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Give a₁₀ = 67 and a₁ = 4 , then

a₁ + 9d = 67

4 + 9d = 67 ( subtract 4 from both sides )

9d = 63 ( divide both sides by 9 )

d = 7

Answer:

23.83

Step-by-step explanation:

Answer:

x = 9

Step-by-step explanation:

Each angle equals 60 since it is an equilateral triangle

7x-3 = 60

add 3

7x = 63

divide by seven on both sides

x = 9

Answer:

70-x

Step-by-step explanation:

The expression which represents the change that Ingrid will get back for purchasing for $x will be 70 - x thus option (C) is correct.

A mixture of variables, numbers, addition, subtraction, multiplication, and division are called expressions.

A statement expressing the equality of two mathematical expressions is known as an equation.

As per the given,

Amount of money that Ingrid have = $70

Amount of money Ingrid purchased = $x

Change back = 70 - x

Hence "The equation that describes the change Ingrid will receive for spending $x is 70 - x".

Answer:

You would pay $30.6, and the discount would be $3.4

Step-by-step explanation:

Because it is a 10% discount, you will only have to pay 90%. So: 0.9*34=30.6

Another way to solve it would be to calculate 10%, which would be 3.4, so 34-3.4=30.6

Answer:

y = 2/5x

Step-by-step explanation:

in order to get the y-intercept (b) , the value of x has to be zero. we already have the y-intercept which is zero. so far, the equation looks like this:

y = mx + 0

in order to find the slope, we'll do y2-y1 / x2 - x1:

2-0

5-0

m is 2/5, so the answer is:

y = 2/5x
