Write an equation that you can use to solve for x enter your answer in the box

Mathematics
1 answer:
tamaranim1 [39]3 years ago
6 0

Answer:

see explanation

Step-by-step explanation:

The 2 angles form a right angle = 90°

Thus the sum of the 2 angles equals 90, that is

x + 63 = 90 ← is the equation

To solve for x subtract 63 from both sides

x = 27

---------\\
n=10
\end{cases}\implies 180(10-2)\implies 1440\\\\

\begin{array}{lclll}
&x + 5\\&x + 10\\&x + 20\\&x + 30\\&x + 35\\&x + 40\\&x + 60\\&x + 70\\&x + 80\\+&x + 90\\
&----\\
&10x+440
\end{array}\implies 
\begin{array}{llll}
10x+440=1440
\\\\\\
10x=1000
\\\\\\
x=\cfrac{1000}{10}\implies x=100
\end{array}

so.. to get every angle, simply plug in 10 for "x" for each.

Mr. Moretti is making welcome bags to give to the 18 students in his homeroom on the first day of school he puts m mechanical pe
Mashcka [7]

Answer:

The total number of pencils is 6

Step-by-step explanation:

According to the given scenario, the computation of the total number of pencils is as follows:

There are 18 students

And let us assume there is m mechanical pencils that put in each bag

also he put twice of the regular pencil

So if he put the 3 mechanical pencil

So, the total number of pencils is

= 3 × 2

= 6

As it twice of the regular pencil

hence, the  total number of pencils is 6

Show that the following rational number by expressing it as a ratio quotient of two integers 0.9
kipiarov [429]
A rational number can be expressed in the form a/b, where a and b are other integers.  To satisfy this definition, 0.9 can be written as 9/10, 18/20, 90/100, etc.

44 markers cost $7.04 Which equation would help determine the cost of 7 markers?
Montano1993 [528]

Answer:

<u><em>(7.04/44)*7</em></u>

<u><em>7*(7.04/44)</em></u>

Step-by-step explanation:

you have to find the cost of each individual marker:

$7.04/44= .16 <em>(Checked it on a calculator)</em>

then you multiply .16 by 7 because each marker costs 16 cence and you need to find the total cost of 7 markers so your equation should look like:

#1 way to write it: (7.04/44)*7

#2 way to write it: 7*(7.04/44)

function f(x) has a slope of 3/2 and a y-intercept of 6. explain how the graph of f(x) could be used to find the x-intercept
kvv77 [185]

Answer:

x - intercept = -4

Step-by-step explanation:

We are told the function f(x) has a slope of 3/2 and a y-intercept of 6.

From general line equation, the formula is; y = mx + c

Where m is the slope and c is the intercept.

Thus, the equation is;

f(x) = (3/2)x + 6

Now,to find the x-intercept on the graph, it will be at a point where f(x) = 0.

Thus let's put 0 for f(x) to find the x-intercept.

0 = (3/2)x + 6

(3/2)x = -6

x = -6 × 2/3

x = -4
