Since Angle DEF is a right angle (i.e 90°) and it is equal to the sum of Angles GEF and GED, so

Angle GED = 28°

Answer:

21. m<2 = 31 degree

22. m<11 = 96 degrees

23. m<5 = 127 degree

24. m<12 = 84 degree

25. m<6 = 53 degree

Step-by-step explanation:

21 explain) m<8 = m<1 = 149 degree b/c Alternate angle rule

                  m<1 + m<2 = 180 b/c straight line is 180 degrees

                  m<2 = 180 - m<1

                  m<2 = 180 - 149 = 31 degrees

25 explain) m<3 = m<6 = 53 degree b/c Alternate angle rule

22. explain) m<7 = m<8 - 180 b/c straight line is 180 degrees

                    m<7 = 180-149 = 31

                    m<11 = 180 - m<7 - m<6

                    m<11 = 180 -31 -53 = 96 degrees

24. explain) 180 = m<11 + m<12 b/c straight line is 180 degrees

                    180 - m<11 = m<12

                     180 - 96 = m<12

                      84 = m<12

25. explain) m<3 = m<6 = 53 degree b/c Alternate angle rule

                   180 = m<5 + m<6 b/c straight line is 180 degrees

                      180 - m<6 = m<5

                     180 - 53 = m<5

                      127 = m<5

2 · c + 2 · (c - 2) =

= 2c + 2c - 4 = 4c - 4 ← the end

Answer:

The perimeter is 4c - 4

Step-by-step explanation:

We will use the Rectangle Perimeter formula:

P = 2(l + w)

Given:

l = c

w = c - 2

Now, we just plug them into the formula:

P = 2(l + w)

P = 2(c + c - 2)

P = 2(2c - 2)

P = 4c - 4

Answer:

-4

Step-by-step explanation:

-7y = 28

divide both sides by 7 to make y the subject of the formula

-y = 28/7

-y = 4

therefore

y= -4

Answer:

y = -4

Step-by-step explanation:

This is a weird question. It depends on what they mean by 'solve' If you're trying to isolate the variable, which is typically what they mean when they say solve, then it can only be done through division, not addition and subtraction.

It would be like this:

[tex]\frac{-7y}{-7} = \frac{28}{-7}\\y = -4[/tex]

If perhaps they want you to get everything on one side of the equation you could just add 7y to both sides and end up with:

7y + 28 = 0

But that doesn't really do anything useful.

pls mark me as brainliest

Answer:

15

Step-by-step explanation:

Given the formula:

[tex] \displaystyle \large{V= \frac{1}{3} Ah}[/tex]

We want to isolate A-term. First, 1/3 • Ah can be written as:

[tex] \displaystyle \large{V= \frac{Ah}{3}}[/tex]

Since we have 3 as the denominator, we multiply the whole equation by 3.

[tex] \displaystyle \large{V \times 3= \frac{Ah}{3} \times 3} \\ \displaystyle \large{3V= Ah}[/tex]

Then we move h to divide 3V since h is multiplied by A.

[tex] \displaystyle \large{ \frac{3V}{h} = A}[/tex]

Therefore, A = 3V/h

Answer:

B: 2x= -14

Step-by-step explanation:

180° is max for a triangle so subtract the given angle. 180- 84 is 96. the equation you get left with is 96= x + 59 + x + 51, which can become 2x + 110=96. Subtract 110 from 96 to get 2x by itself, which is now -14.

Step-by-step explanation:

Answer:

5p - r +3

Step-by-step explanation:

Question shows - (r-3-5p)

- r - - 3 - - 5 p   we can simplify and separate and instruct each value then add your brackets.

- r - ( -  3) - (- 5)

- r + 3 - ( - 5p) and see that the - - 5p  =  + 5p

-r + 3 + 5p  then rearrange and keep format.

5p -r + 3

The total simple interest earned in the time of 10 years when investing a principal amount of $500 at the rate of interest of 1.7% is $85.

When we invest an amount, we receive the benefits of investing the amount. The benefit is called the interest. The interest is usually earned in monetary terms only.

Two common types of interest earned are:

In the above formulas, P is the Principal amount invested, n is the time for investment, and r is the rate of interest.

In the question, we are said that Dean invests $500 for 10 years at a rate of 1.7% per year simple interest.

We are asked to find the total interest Dean earned in the time of 10 years.

We will use the formula for simple interest (S.I.), according to which:

S.I. = Pnr, where P is the Principal amount invested, n is the time for investment, and r is the rate of interest.

In our case,

The principal investment P = $500

The rate of interest r = 1.7%

The time for investment n = 10 years.

∴ Simple Interest (S.I.) = $500*10*1.7% = $5000*0.017 = $85

Friend is not correct. Instead of finding difference   , the fractions are added and then simplified.

Given :

The difference of fractions

[tex]\frac{3}{2} -\frac{9}{2} =\frac{3}{2}+ \frac{9}{2} =\frac{12}{2} =6[/tex]

We are asked to find the difference between 2 fractions

[tex]\frac{3}{2} -\frac{9}{2}[/tex]

Here , the denominators are same . So we can subtract the numerators

But in the second step , the negative sign becomes positive

Instead of finding difference both the fractions are added.

So the mistake is in step 2

Both the fractions are added instead of subtraction .

Correct steps are

[tex]\frac{3}{2} -\frac{9}{2} =\frac{3-9}{2} =\frac{-6}{2} =-3[/tex]

Answer:

f(x) = - [tex]\frac{5}{4}[/tex] x + 2

Step-by-step explanation:

Note that y = f(x)

Rearrange making y the subject

- 5x - 4y = - 8 ( add 5x to both sides )

- 4y = 5x - 8 ( divide terms by - 4 )

y = - [tex]\frac{5}{4}[/tex] x + 2 , that is

f(x) = - [tex]\frac{5}{4}[/tex] x + 2
