Step-by-step explanation:

The expression for the total distance covered.

k + (k + 8) + (k - 2)

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Distance biked:

Jackson = k

Maria = k + 8

Peter = k - 2

Now,

The total distance biked.

= k + k + 8 + k - 2

= 3k + 6

= 3 (k + 2)

Thus,

The total distance covered is 3 (k + 2).

Answer:

the slope intercept-form of an equation of a line is y=mx+b

Given that the slope is 3 and a point on the line is P(-2, 4), then

m=3 and from the point (-2, 4), x=-2 and y=4.

Step-by-step explanation:

y=mx+b.

4=3(-2)+b   Now solve for b.

4=-6+b

4+6=b

10=b

Now you know b=10 and you already know the slope m=3. Substitute these values into y=mx+b. When you do you will get y=3x+10. This is your answer in slope intercept form.

Complete question :

Miranda is braiding her hair then she will attach beads to the braids she wants 1/3 of the beads to be red if the greatest number of beads that will fit on the braid is 12 what other fraction could represent the part of the beads that are red?

Answer:

2 / 6

Step-by-step explanation:

Fraction of red beads on braid = 1/3

greatest number of braids = 12

Fraction of red beads = (1 /3) * 12 = 4 red beads

Thus implies that :

When greatest number of braids = 12

fraction of red beads) = (Number of red beads / greatest number of beads)

Fraction = 4 / 12

Divide by 2 = 2/6 (don't reduce to lowest term).

3a + 11 > 5

Subtract 11 from both sides:-

3a > 5 - 11

3a > -6

a > -2

Answer:

It would be the first one

Step-by-step explanation:

problem---> 3a + 11 > 5

FIND a

1. Subtract 11 from both sides:-

which would look like this "3a > 5 - 11"

=3a > -6

Answer:

Sale price of the watch = $60

Step-by-step explanation:

Given that:

Cost of the watch at Macy's = $150

Discount on watch = 60%

Amount of discount = 60% of cost

Amount of discount = [tex]\frac{60}{100}*150[/tex]

Amount of discount = 0.60*150 = $90

Price after discount = 150-90

Price after discount  = $60

Hence,

Sale price of the watch = $60

First you want to get n on the side by itself.

So 9n-24=4n+6 you want to add 24 to both sides so you get 9n=4n+30 than you want to subtract 4n from both sides to get 5n=30 than divide 5 from both sides to get n by itself and you will get n=6

Answer:

25

Step-by-step explanation:

Step one:

given data

We are told that Shaneya purchased a membership to play basketball at her local gym.

Costs =  $75 for the year,

Rent =  $3 for equipment each time she goes

Given that she has $150 to spend,

Step two:

Firstly, let us model the situation

let the total amount she has to spend be y

and the number of time she goes to the gym be x

y= 75+3x

for y= 150, let us find the value of x

150= 75+3x

150-75= 3x

75= 3x

divide both sides by 3

x= 75/3

x=25 times

The maximum amount of times is 25

Answer:

Option D is correct .

Step by step explanation:

A function is given to us and we need to find its inverse . The function is g(x) = -2x⁵ - 2.

So for finding its inverse , exachange x with y .

⇒ g(x) = -2x⁵ - 2 .

Let g(x) = y ,

⇒ y = -2x⁵ - 2 .

Replace x with y ,

⇒ x = -2y⁵ - 2

⇒ x + 2 = -2y⁵

⇒ y⁵ = x+2 / -2

⇒ y⁵ = (-1) ( x + 2) / (-1)(-2)

⇒ y⁵ = -x - 2/ 2

⇒ y = ⁵√ [ ( -x -2)/2 ]

Hence the inverse of the function is ,

-√5/5

Step-by-step explanation:

Given the following

sin(A) = 4/5

sinB - -2√5/5

SinA = 4/5 = opp/hyp

We can get cosA

opposite = 4

hypotenuse = 5

Adj = √5²-4² (pythagoras theorem)

Adj = √25-16

Adj = √9

Adj = 3

Cos A = Adj/hyp

Cos A = 3/5

Also

Sin B = -2√5/5 = opp/hyp

opposite = -2√5

hypotenuse = 5

Adj = √5²-(2√5)² (pythagoras theorem)

Adj = √25-20

Adj = √5

Cos B = Adj/hyp

Cos B =  √5/5

Evaluate cos (A-B)

cos (A-B) = cosAcosB + sinAsinB

cos (A-B) = 3/5(√5/5)+4/5(-2√5/5)

cos (A-B)  = 3√5/25 - 8√5/25

cos (A-B) = -5√5/25

cos (A-B) = -√5/5

Hence the value of cos (A-B) is -√5/5

Answer:

Solving the expression and round to the nearest hundredth

[tex]0(5x+2)=2(9x-6)[/tex] we get [tex]\mathbf{x=0.67}[/tex]

Step-by-step explanation:

We need to solve the expression and round to the nearest hundredth

[tex]0(5x+2)=2(9x-6)[/tex]

Solving:

[tex]0(5x+2)=2(9x-6)[/tex]

We know that multiplying anything by zero we get zero

[tex]0=2(9x-6)[/tex]

Switching sides

[tex]2(9x-6)=0[/tex]

Multiplying 2 with terms inside the bracket

[tex]18x-12=0[/tex]

Adding 12 on both sides

[tex]18x-12+12=0+12\\18x=12[/tex]

Divide both sides by 18

[tex]\frac{18x}{18}=\frac{12}{18}\\x=0.666[/tex]

Rounding to nearest hundredth we get:

[tex]x=0.67[/tex]

So, solving the expression and round to the nearest hundredth

[tex]0(5x+2)=2(9x-6)[/tex] we get [tex]\mathbf{x=0.67}[/tex]

12 x 8 is 96. Since a bucket of paint can cover 75,you would subtract 96 from the 75.That gives you 21.So if she only has one gallon,only 21 will remain unpainted.
