Answer:

The answer is 1 5/12 or 17/12.

Step-by-step explanation:

First we turn 5 2/3 into a Improper fraction.

5 2/3 = 17/3

Next we change 4 to 1/4 then multiply 1/4 by 17/3.

17/3 * 1/4 = 17/12

17/12 = 1 5/12

Hope this helps! :)

Answer:

17/12

Step-by-step explanation:

5[tex]\frac{2}{3}[/tex] / 4 = [tex]\frac{17}{3}[/tex] / [tex]\frac{4}{1}[/tex] = [tex]\frac{17}{3}[/tex] * [tex]\frac{1}{4}[/tex] = 17/12

Answer:

5, 10 and 11 feet.

Step-by-step explanation:

Let length of first side be x feet then

second side  = 2x feet

third side = 2x + 1 feet.

So we have the equation:

x + 2x + 2x + 1 = 26

5x + 1 = 26

5x = 25

x = 5 feet.

So first side = = 5 feet, second = 10 and third = 11 feet.

Actually Welcome to the Concept of the exponents and indices.

here, we should remember one thing that,

3 ^3 = 27 and 1/3^x = 3^-x

so we get as,

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

==> 3^-12+3x = 3^6x-3

since the base is same that is 3 , we equate their powers.

-12x+3=6x-3

==> 3+3 = 6x+12x

==> 6 = 18x

hence ===> x = 6/18 = 1/3

hence, x = 1/3

y = -3x + 3

Step-by-step explanation:

So, basically I can't remember how to do this the long way but I used a calculator on Desmos (the graphing one to be specific). You should be able to find tutorials on how to use it and graph problems to find their answers but if not, you can just message me and I'll walk you through how to use it.

As for the form it asked for in the question, slope-intercept form is just:

y = mx + b

m is the slope, and b is the y-intercept (the place where the line crosses the y-axis)

Step-by-step explanation:

Answer: 1) 13    2) 11, 144°, 36°   3) 18, 54°, 126°

Step-by-step explanation:

For the first one to find x make the equations equivalent to each other

to make an equation.

7x - 16 = 5x + 10   // Now solve for x

add 16 to both sides

7x = 5x + 26

subract 5 from both x

2x = 26

Now divide by 2

x = 13

For the 2nd one do the same thing as last time because the equations are across from each other in parallel lines meaning they are equivalent.

12y + 12 = 15y - 21

add 21 to both sides

12y + 33 = 15y

subtract 12 from both y

33 = 3y

Now divide by 3

y = 11

Angle A is 144°

Angle B is 36°

Now solve for A ( replace y by 11 in the equation a to get an output )

12(11) +12

132 + 12 = 144°

Now to find b subtract 144 from 180

180 - 144 = 36°

For the 3rd one same thing since they are parallel.

5z - 36 = 3z

add 36 to both sides

5z = 3z + 36

now subtract 3 from both z

2z = 36

divide by 2

z = 18

Solve for C

5(18) - 36

90 - 36 = 54°

Z is 18

angle C is 54°

angle D is 126°

Answer:

Step-by-step explanation:

Depends on what kind of rotation you would be doing. But for example, if you are rotating 90 degrees about a point on a graph, your point (x, y) changes to (-y, x). Then another 90 degrees would be (-x, -y).

Answer:

The annual profits will be 2187.5

Step-by-step explanation:

p(x) = 65x - 0.3x^2

I am guessing that the 2 was supposed to be a square.

Simply plug in the number of pies sold:

p(175) = 65(175) - 0.3(175)^2 = 11375 - 0.3*30625 = 11375 - 9187.5 = 2187.5

Answer:

10a - 30b + 40

Step-by-step explanation:

Multiply each term inside the ( ) by the 5 outside the ( ).

5 x 2a = 10a

5 x -6b = -30b

5 x 8 = 40

Add the terms together (don't forget that it's negative 30b)

10a + -30b + 40 = 10a - 30b + 40

Answer:

1/6

Step-by-step explanation:

To know what fraction is equal to 50% of 1/3, we have to convert the percentage into a fraction first.

50% = 50/100

So 50% of 1/3 = 1/3 * 50/100

= 50/ 300

= 5/30

= 1/6

Answer:

1/6

Answer:

[tex]y=-\frac{1}{5}x+6[/tex]

Step-by-step explanation:

We have the following equation

y=mx+b

where m is the slope

and b is the y intercept

we know that the slope is  -1/5 (or -.2)

which means that so far our equation looks like this

y= -.2x+b

which means we need to solve for b

we know that when x= -5 y= 7 which means we can plug in those values and solve for b

we have

7= (-.2*-5)+b

7=1+b

b=6

which means our equation is as follows

y= -1/5x+6

1/4 = .25 add .25 to 5 and then divide 25 by 5.25 to get the answer

Answer:

x=80

Step-by-step explanation:

1/4x + 5 = 25

multiply both sides by 4

x+20=100

subtract both sides by 20

x=80
