i just want to tell everyone their doing great

Answer:

6) 9x-25+9x-25(sum of base angles)

9x-25+9x-25+104=180(sum of angles in a triangle)

collect like terms

9x+9x-25-25+104=180

18x-50+104=180

18x+54=180

18x=180-54

18x=126

divide both sides by 18

18x÷18=126÷18

x=7

Answer:x=

14 y=12

Step-by-step explanation:

Answer:

x = 36

Step-by-step explanation:

Given

[tex]\sqrt{x+13}[/tex] = 7 ( square both sides )

([tex]\sqrt{x+13}[/tex] )² = 7²

x + 13 = 49 ( subtract 13 from both sides )

x = 36

[tex]\sqrt{x+13}=7\\[/tex]

To solve the radical equation, completing the square all whole equation.

[tex](\sqrt{x+13})^2=7^2\\[/tex]

As defined, [tex](\sqrt{x})^2 =|x|[/tex]

Therefore, [tex](\sqrt{x+13})^2=|x+13|=x+13[/tex]  (Although Absolute Function gives 2 conditions, however - domain of radical function must be greater than or equal to 0. Meaning x < 0 for another condition doesn't apply.)

[tex]x+13=49\\x=49-13[/tex]

Move 13 to subtract.

[tex]x=36[/tex]

Therefore, the answer is x = 36.

Answer:C) 15

Step-by-step explanation:

If she drives 1/4 mi in 2 minutes then she wouldve drive 1 mi in 8  minutes.

2 hours= 120 minutes

8/120=15

Answer/Step-by-step explanation:

George:

4.3% ÷ 100 = 0.043

0.043 × 5000 = 215

John:

4% ÷ 100 = 0.04

0.04 × 5500 = 220

End of 6 years:

George: 215 × 6 = 1290

John: 220 × 6 = 1320

John has earned the most interest at the end of 6yrs. $1320

Should be 26, I believe.

Answer: 26

Percentage Calculator: 52 is what percent of 200? = 26.

Hope this helps..... Stay safe and have a great Christmas!!!! :D

each friend will get

$ 10.75 because 43.00 is 10.75 if u divide it by 4 u will get 10.75

Answer:

$10.75

Step-by-step explanation:

If there are 4 friends evenly dividing $43.00 then you divide

43 by 4 to get

$10.75

Answer:

r=-17

Step-by-step explanation:

Answer:

20x+8+7=-105

20x(8+7)=-105

-15 to both sides 20x=-120

divide by 20 to both sides -120/20=-6

x=-6

Step-by-step explanation:

Alternate exterior angles are angles that are on different sides of the transversal and on the outside of the parallel lines. There is a theorem that says that alternate exterior angles are congruent if two parallel lines are cut by a transversal.

Answer:

Answer is 51+20-51+3=23.

Step-by-step explanation:

Hope you have a wonderful Christmas and New Years. Thank you this was so nice

Answer:

23

Step-by-step explanation:

51+20-51+3

= 51+20= 71

= 71+3= 74

= 74-51= 23

Answer:

There is one solution

Step-by-step explanation:

2x + y = -1

8x + 3y = -2

Multiply the first equation by -4

-8x -4y = 4

Then add the equations together to eliminate x

-8x -4y = 4

8x + 3y = -2

--------------------

   -y = 2

Multiply by -1

y =-2

Now find x

2x+y =-1

2x+-2 =-1

Add 2 to each side

2x-2+2=-1+2

2x=1

Divide by 2

x = 1/2

Given:

Amount in the savings account = 4300

Each week, Raul pays the dog sitter 30 from his savings account.

To find:

The function, f(x), that is equal to the amount of money in the account after Raul pays the dog sitter each week.

Solution:

Let x be the number of weeks.

Raul pays the dog sitter in 1 week = 30

Raul pays the dog sitter in x week = 30x

Remaining amount = Initial amount - Amount he pays the dog sitter

[tex]f(x)=4300-30x[/tex]

Therefore, the required function is [tex]f(x)=4300-30x[/tex].

Answer:

Your slope would be -1/10

Step-by-step explanation:

To find the slope from two points, you would use the formula y2-y1/x2-x1

In this case, the equation would look like -4-(-3)/5-(-5)

-4 - (-3) = -1

5 - (-5) = 10

-1/10 = -1/10

Answer:

4th and 5th

Step-by-step explanation:

Answer:

for the first one: x = -25/3 or -8.333333

for the second one: x = 29-8y/9

Step-by-step explanation:

for the first one:

add 8 to both sides 3x=-33 + 8

simplify -33+8 to -25

divide both sides by 3

which gives you -25/3 or 8.333333

for the second one:

subtract 8y from both sides 9x=29-8y

divide both sides by 9

which gives you x= 29-8y/9

Answer:

[tex]y=45+60x[/tex]

Step-by-step explanation:

Step one:

given data

The  charge is $45 to install the cable box and $60 for each month of service

Required

The linear expression for the situation.

Step two:

let the number of months be x and let the total charges be y

Hence the expression for the total charges is
