If The Perimeter Of This Triangle Is 15 Centimeters, What Is The Value Of N?5n - 6n2n + 1Express Your
Answer 2

The value of n that makes up the triangle of perimeter 15 centimeters is 2.5

How to determine the value of n?

The side lengths of the triangle are given as:

5n - 6, n and 2n + 1

The perimeter is given as:

P = 15

The perimeter is the sum of the side lengths.

So, we have:

5n - 6 + n + 2n + 1 = 15

Collect like terms

5n + n + 2n = 15 + 6 - 1

Evaluate the like terms

8n = 20

Divide both sides by 8

n = 2.5

Hence, the value of n that makes up the triangle is 2.5

Answer:

B. 13

Step-by-step explanation:

[tex]m(m + n) - n[/tex]

[tex]m = 5 \\ n = - 3[/tex]

Substitute m = 5 and n = - 3 in the expression.

[tex]5(5 + ( - 3)) - ( - 3) \\ 5(5 - 3) + 3 \\ 5(2) + 3 \\ 10 + 3 \\ 13[/tex]

Remind that negative multiply negative must equal positive.

The answer is 13 ! :) 5(5+(-3))-(3-)= X
Distribute 5
25+(-15)-(-3)
The minus (-3) turns into a positive so you get +3 and you add it all together and get 13 :)

Answer:

y<-2x-3

Step-by-step explanation:

Your first step is to find the equation of the line. You can see that the y-intercept is -3, therefore your b is -3. So now your formula looks like this:

y=mx-3

To find m, you substitute in an x value and its corresponding y value. When you do this you will get -2.

Now it looks like this:

y=-2x-3.

Now that you have the equation of the line, you can look at the inequality. Since the line is dotted, that means it is not included in the inequality. That mean it cannot contain an equal to. So the only options we have are < and >. Since the shaded area is to the left, which is the negative side, we can conclude that y<-2x-3 is the correct equation.

4(2a + 2) = 8(2 - 3a) whats A? please help me!!!!

Answers

Answer:

a = [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

4(2a + 2) = 8(2 - 3a)

Distribute.

8a + 4 = 16 - 24a

Add 24a to each side.

32a + 4 = 16

Subtract 4 from each side.

32a = 12

Divide 32 from each side.

a = [tex]\frac{3}{8}[/tex]

Step-by-step explanation:

i think... seems the only reasonable answer

The cost of one hat is $1 and cost of one mask is $1.

What is Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

We have 10 hats and 20 masks were sold for $30.

and, 8 hats and 10 masks were sold for $18.

let the cost of one hat be H and cost one Mask be M.

So, the system of Equation we get

10H + 20M = 30..........(1)

8H + 10M = 18...........(2)

Solving the above equation we get

10H - 16H = 30 - 36

-6H = -6

H = 1

and, 10 + 20M= 30

20M= 20

M= 1
