 Sum of both the angle will 180 because of linear pair

now, 10x - 20 + 6x + 8 =. 180 

 16x - 12 = 180

16x = 192 

x= 192/16

x = 12

1st angle = 100

2nd is = 80

Hope it helps and your day will full of happiness

If Company M ordered a total of 50 computers and printers and Company N ordered a total of 60 computers and printers, how many c

Ad libitum [116K]

Answer:

Available information is not sufficient to solve the questions

Step-by-step explanation:

Let Cm = Computers Ordered by Company M

Let Cn = Computers Ordered by Company N

Let Pm = Printers Ordered by Company M

Let Pn = Printers Ordered by Company N

Cm + Pm = 50 --- Equation 1

Cn + Pn = 60 ----- Equation 2

1. Company M and N ordered the same number of computers

Here,

Cm = Cn

Substitute Cm for Cn in equation 2

Cm + Pm = 50

Cm + Pn = 60

Subtract Equation 2 from 1

Pm - Pn = 50 - 60

Pm - Pn = -10

Pm = Pn - 10

Substitute Pn-10 for Pm in equation 1

Cm + Pn - 10 = 50

Make Pn the subject of formula

Cm = 50+10-Pn

Cm = 60 - Pn

Hence, the number of computers ordered by Company M is 60 minus the number of printers ordered by Company n

2. Company N ordered 10 more printers than Company M.

Here,

Pn = 10 + Pm

Make Pm the subject of formula

Pm = Pn - 10

Substitute Pn-10 for Pm in equation 1

Cm + Pn - 10 = 50

Make Cm the Subject of formula

Cm = 50 + 10 - Pn

Cm = 60 - Pn

Hence, the number of computers ordered by Company M is 60 minus the number of printers ordered by Company n

Condition 1 and 2 points to the same result

F(x)=3x 2+x Find f(−5)

Zina [86]

$\huge \boxed{\mathfrak{Question} \downarrow}$

f (x) = 3x² + x
Find f (-5).

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

Given,

f (x) = 3x² + x

Now, we have to find f (-5). To find this, we just need to substitute -5 in the place of x.

So,

$\sf \: f(x) = {3x}^{2} + x \\ \\ \sf \: \: Substitute \: x \: as \: - 5. \\ \\ \sf \:f( - 5) = 3( - 5) ^{2} + ( - 5) \\ \\ \sf \:Calculate \: -5 \: to \: the \: power \: of \: 2 \: and \: get \: 25. \\ \\\sf \: 3\times 25+5 \\ \\ \sf \:Multiply \: 3 \: and \: 25 \: to \: get \: 75. \\ \\\sf \: 75+5 \\ \\\sf \:Add \: 75 \: and \: 5 \: to \: get \: 80. \\ \\ = \boxed{\boxed{ \bf \: 80}}$

Analyze Manda's work. Is she correct? If not, what was her mistake?

yulyashka [42]

Answer:

Option 3. In step 3, she did not subtract one x from the left side

Step-by-step explanation:

we have the repeating decimal

0.272727...

Convert to fraction number

step 1

Let

x=0.272727...

step 2

Multiply by 100

100x=27.272727...

step 3

Subtract x from 100x

100x-x=27

99x=27

step 4

Find the value of x

x=27/99

therefore

Manda's work is not correct

In step 3, she did not subtract one x from the left side
