x/5 + 2 = 19 x______​

Answers

Answer:

47x=5

or 5/47

Step-by-step explanation:

Answer:

x=85

Step-by-step explanation:

x/5 + 2 = 19

5(x/5 + 2) = 5(19) *multiply both sides of the equation by 5 to get rid of the fraction

x + 10 = 95

x = 85 *subtract 10 on both sides

Check:

x/5 + 2 = 19

85/5 + 2 = 19

17 + 2 = 19

19 = 19

In how many ways can you answer a 13-question true-false test if you answer each question with either a "true" or a "false"?

Answers

Answer:

[tex]\frac{1}{1892}[/tex]

Step-by-step explanation:

There are two possibilities for each of 13 questions, true or false.  As a result, you have a [tex]\frac{1}{2}[/tex] chance of choosing either of the choices.  To find this, you would multiply the probability to the power of the number of cases, meaning [tex](\frac{1}{2^(13)})=\frac{1}{1892}[/tex].

Answer: w^2 + 15w + 54

Step-by-step explanation:

FOIL = first, outside, inside, last.

First —> multiply first numbers of each parentheses.

Outside —> multiple the OUTSIDE numbers in each parentheses (first number in the first parentheses, second number in the second parentheses.

Inside —> multiply the INSIDE numbers in each parentheses (the second number in the first parentheses, first number in the second parentheses).

Last —> multiply second number of each parentheses.

(W + 9)(w + 6)

F = w^2

O = 6w

I = 9w

L = 54

W^2 + 6w + 9w + 54

Write a polynomial in standard form that represents the area of the shaded region.

Answers

Answer:

[tex]A=p^2-2p-3[/tex]

Step-by-step explanation:

The area for a triangle is given by:

[tex]\displaystyle A=\frac{1}{2}bh[/tex]

The base is p + 1 and the height is 2p - 6. Therefore:

[tex]\displaystyle A=\frac{1}{2}(p+1)(2p-6)[/tex]

Simplify the second term:

[tex]\displaystyle A=(p+1)(\frac{1}{2})(2p-6)=(p+1)(p-3)[/tex]

Distribute:

[tex]A=p(p-3)+1(p-3)[/tex]

[tex]A=p^2-3p+p-3[/tex]

Combine like terms:

1. Let the side length of each small square on the grid represent 1 unit. Draw two different triangles, e. Ach with base 5 1/2 units and area 19 1/4 units2. 2. Why does each of your triangles have area 1914 units2?

Answers

Answer:

Step-by-step explanation:

Given that:

Each small square on a grid represents 1 unit

Base of triangle = 5 1/2 units = 11/2

Area of triangle = 19 1/4 unit² = 77/4

The Area, A of a triangle is obtained thus :

77/4 = 1/2 * 11/2 * h

77/4 = 11/4 * h

h = 77/4 ÷ 11/4

h = 77/4 * 4 /11

h = 7 units

Find the measure of

Answers

Answer:

19 degrees.

Step-by-step explanation:

First solve the angles in the top triangle:

FHG = 180 - 135 = 45 (angles on a straight line = 180)

FGH = 180 - 105 = 75 (angles on a straight line = 180)

Using these we get HFG = 180 - 45 - 75 = 60 (angles in a triangle = 180)

Then because HFG is directly opposite DFC on the crossed lines, we know they are equal: DFC = 60

FDC = 180 - 119 = 61 (anges on a straight line = 180)

Now if we label ABC (the target angle) as x then we known ACB = 180 - 40 - x.

With this we know FCD = 180 - ACB = 180 - (180 - 40 - x) = 40 + x (angles on a straight line).

Finally using the FDC triangle we have 40 + x + 60 + 61 = 180 so x = 180 - 40 - 60 - 61 = 19 degrees.

Answer: The answer in this photo thanks for a little quiz

The number of day it will be until Addison and Bert each have  read the same number of pages in total is 8 days.

What is an equation?

In mathematics, an equation is a statement of equality between two expressions, indicated by the equals sign (=). Solutions to equations are the values for unknowns which, when substituted into the expression, make it true.

Given that, the book they're reading right now is 256 pages long.

Let the number of days be x.

Addison has read 102 pages so far and decides to read 16 pages every day until she finishes the book.

102+16x -------(i)

Bert has read 142 pages, and he plans to read 11 pages every day.

142+11x -------(ii)

Addison and Bert have each read the same number of pages in total.

So, (i)=(ii)

102+16x=142+11x

16x-11x=142-102

5x=40

x=8

Hence, the number of day it will be until Addison and Bert each have  read the same number of pages in total is 8 days.

How many multiples of 5 are there in between 100 and 300?

Answers

Answer:

39 multiples

Step-by-step explanation:

Consider AP:

105, 110, ..., 295

As multiples of 5 between 100 and 300

The first term is 105, the common difference is 5, the last term is 295.

Use the nth term formula:

105 + 5(n - 1) = 2955(n - 1) = 190n - 1 = 190/5n - 1 = 38n = 39

Answer:

Solution given:

first term [a]=100

last term[l]=300

common difference [d]=5

second term[b]=100+5=105

now

we have

l=a+(n-1)d

substituting value

300=100+(n-1)5

300-100=(n-1)5

200/5=n-1

40=n-1

n=40+1

there are 41 multiple in between 100 and 300/including it but no including its 41-2=39 multiple
