Answer:

1/3

Step-by-step explanation:

The most important thing to remember is that the poster is divided into three equal parts and 1 part of it is for his neighborhood friends and another one part of it is for his friends from school. The denominator would be three and the numerator would be the 1 part he uses for his friends from school.

x = # of miles

$59.31 = $31 + $0.19x

Subtract $31 from both sides

$28.31 = $0.19x

Divide both sides by $0.19

149 = x

Answer:

56 underwater breathing potions.

Step-by-step explanation:

Written algebraicly, f=m+10 and b=3m+2, with f being flying potions, b being breathing underwater, and m being mind reading potions. We know that f+b+m=102, so replace f and b with the equations. You get m+10 + 3m+2 + m +102. Combine like terms to get 5m+12+102. Subtract 12 from both sides to get 5m=90, and divide both sides by 5 to get m=18. Now take b=3m+2 and replace m with 18. Now you have b=3(18)+2. 3 times 18 is 54, plus 2 is 56. :)

Answer:

a nagitive integer

Step-by-step explanation:

an integer is a whole number

Steps to solve:

f(x) = 14 - 0.5x when x = 30

~Substitute

f(30) = 14 - 0.5(30)

~Simplify

f(30) = 14 - 15

~Subtract

f(30) = -1

Answer:

-11

Step-by-step explanation:

Answer:

[tex]x=-11[/tex]

Step-by-step explanation:

[tex]-1=\frac{\left(5+x\right)}{6}[/tex]

Switch sides:

[tex]\frac{\left(5+x\right)}{6}=-1[/tex]

Multiply both sides by 6:

[tex]\frac{6\left(5+x\right)}{6}=6\left(-1\right)[/tex]

[tex]5+x=-6[/tex]

Subtract 5 from both sides:

[tex]5+x-5=-6-5[/tex]

[tex]x=-11[/tex]

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

g(x^2 + 2x - 4)

3(x^2 + 2x - 4) + 1

3x^2 + 6x - 12 + 1

3x^2 + 6x - 11

Hey there!

[tex]5x-3x=6x-8[/tex]

Combine like terms.

[tex](5x+-3x)=6x-8\\2x=6x-8[/tex]

Subtract 6x from both sides of the equation.

[tex]2x-6x=6x-8-6x\\-4x=-8[/tex]

In the last step, we will divide both sides by -4.

[tex]\frac{-4x}{-4} =\frac{-8}{-4} \\x=2(ANSWER)[/tex]

Hope this helps and have a great weekend!

Answer: x = 2

Step-by-step explanation: Aquí esta :

Simplificar 5x - 3x y eso se de 2x

1.) 2x = 6x-8

Sustraer 6x-2x

2.) 2x-6x= -8

Y entonces deberías haber obtenido 4x

3.) -4x=-8

Dividir ambos lados por -4

4.) x = -8/-4

Dos negativas hacen una positivo

5.) x = 8/4

Finalmente, la repuesta es :

6.) x = 2

Answer:

answer is D

shown below

The equation of the line that is perpendicular to the given line and passes through the point (3,0) is 3y - 5x = -15.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

We have the points as (-3, 2) and (2, -1).

So, the slope of line

slope = (-1 -2)/ (2 -(-3))

slope = -3/5

So, the slope for the perpendicular line is

slope= 5/3

Now, using the slope intercept form

y= mx+ b

y= 5/3x + b

and, the line passes through (3, 0)

0= 5/3(3)+ b

b= -5

Then, the equation of line is

y= 5/3x -5

3y - 5x = -15

Answer: 1,000

Step-by-step explanation:

1,750 divided by 1.75 =1,000

Answer:

1,000

Step-by-step explanation:

If the class wants to raise a total of $1,750 and make a profit of $1.75 from each candy bar that gets sold then you take the total and divide it by the amount of profit each bar makes. So you do 1,750 divided by 1.75 and that gives you 1,000. So the class must sell 1,000 candy bars to reach their goal.
