What is the solution to the equation −p − 13 = −4 /3 p + 2/3 ( 5p − 6 ) ?

((will give brainliest to best answer

Answers

Answer:

The answer is p= 2 and 1/3

Step-by-step explanation:

This answer can be found using the order of operations to solve for p.

Start by distributing 2/3 by (5p-6)

add -4/3p to 10/3p equaling 6/3p or 2p

subtract 13 from both sides

-p= 2p - 7

p=2 and 1/3

Step-by-step explanation:

a ) 19 + 7 = 26

26 ÷ 2 = 13

13 - 5 = 8 ans

b) (19+7/2)-5

[tex]( \frac{19 + 7}{2} ) - 5[/tex]

hope this answer helps you dear...

Hi !
A
19 + 7 / 2 - 5
According to PEMDAS, division comes first, so we start by diving 7 by 2, which equals 3.5.
19 + 3.5 - 5 = 17.5

B
19 + 7 / 2 - 5
In order for this to equal 8, the brackets will be placed like this: (19 + 7)/2 - 5
It gives (26)/2 - 5
Then we divide 26 by 2 (according to PEMDAS once again)
We get 13 - 5 = 8

C
19 + 7 / 2 x 6 + 1
In order to get 2 as an answer, we place the brackets this way:
(19 + 7)/(2 x 6 + 1)
(26)/(12 + 1)
26/13 = 2

Hope it helps!!

On Tuesday at lunchtime, it was -10°C. By sunset, the
temperature had dropped 14°C.

Answers

-24 Celsius that is the answer

Answer:

By sunset the temperature was -24

Step-by-step explanation:

The reason for this is you start off with -10, then the word dropping relates to subtraction, meaning that the equation is -10-14, and when you subtract a negative, you are actually adding to it, so you can drop the negative for now, and you have 10+14 which equals 24, then add the sign back in to get -24C.

The length of a rectangular sign is 5 times its width. If the sign’s perimeter is 24 inches, what is the sign’s area The sign's area is ___ square inches.

Answers

The sign's area is 80 square inches.

A rectangle is a quadrilateral. This means that a rectangle has four sides.

The area of a rectangle = length x width

Perimeter of a rectangle = 2 x ( length + width)

Let the width of the sign be represented with w

The length of the sign is 5x

Substitute these dimensions into the formula for the perimeter of a rectangle.

(x + 5x) = 24

6x = 24

x = 24/6

x = 4 inches

The length is 5 x 4 = 20 inches

Area of the sign = 20 x 4 = 80 inches²

Answer:

27/4 or 6 3/4

Step-by-step explanation:

Change all mixed numbers into improper fractions

2 1/9 = 19/9

6 1/4 = 25/4

19/9 ÷ 2/3 - 25/4 x 2/5

dividing fractions you can multiply and use reciprocal of the fraction (means you switch the top and bottom numbers)

19/9 x 3/2 - 25/4 x 2/5

you can reduce the top and bottom numbers to make them smaller by dividing. find a common number to divide them by, you can cross out the numbers and just put the new equation below

19/3 x 1/2 - 5/4 x 2/1

multiply across the fractions first PEMDAS, then subtract

19/6 - 10/4 (multiply by 2 and 3 respectively to get both bottom numbers the same, multiply by the same number on top)

57/12 - 30/12 = 27/12

1/5 x 1/3 + 2/5 x 2/3

1/15 + 4/15 = 5/15 or 1/3

27/12 / 1/3

you can multiply the fractions and flip the top and bottom numbers of 1/3

27/12 x 3/1

reduce 12 and 3

27/4 x 1/1 = 27/4 or 6 3/4

Line L and m are prendicular with point of intersection P. Noah says that a 180 degree rotation with center p has the same effects on points in the plane as reflecting over line m. Do you agree with Noah? Explain your reasoning

Answers

The point of intersection is the point where two or more lines meet.

Noah's claim is incorrect

The given parameters are:

Line l, line m and point of intersection p

See attachment for illustration of the perpendicular lines l and m.

Figure 1 represents the original lineFigure 2 represents the line rotated 180 degreesFigure 3 represents the line reflected over line m

Using the attachment as a guide, we can see that both transformations do not have the same effect on the points on both lines.

This is so because, figures 2 and 3 can be transformed to one another by reflecting across line l.

Hence, Noah's claim is incorrect

Answers

Answer:

The 6 pack

Step-by-step explanation:

i searched it up

The required option that has a lesser price per mini football is a package of 8.

Given that,
at a toy store, Colton can buy a package of 6 mini footballs for $7.50. or a package of 8 mini footballs for $9.60. wich option has the lesser price per mini football is to be determined.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
For 6 package footballs the cost of a mini football = 7.50 / 6 = $1.25.
For 8 package footballs the cost of a mini football = 9.60 / 8 = $1.20.

Thus, the required option that has a lesser price per mini football is a package of 8.

bChoose the equation that represents the graph.

Oy = x - 3
Oy = -x + 3
Oy = -x-3
Oy = x + 3

Answers

The graph illustrates a linear function, because the graph is a straight line

The equation of the graph is (d) y = x +3

The points on the line are:

[tex](x_1,y_1) = (-3,0)[/tex]

[tex](x_2,y_2) = (0,3)[/tex]

First, we calculate the slope (m)

[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]

Substitute values for x1, x2, y1 and y2

[tex]m = \frac{3-0}{0--3}[/tex]

Simplify

[tex]m = \frac{3}{3}[/tex]

Divide

[tex]m = 1[/tex]

The equation of the line is then calculated using the following formula:

[tex]y = m(x - x_1) + y_1[/tex]

Substitute values for m, x1 and y1

[tex]y = 1(x - -3) + 0[/tex]

Simplify

[tex]y = 1(x +3)[/tex]

Open bracket

[tex]y = x +3[/tex]

Hence, the equation of the graph is (d) y = x +3
