find x and y in
(i) 23x- 29y= 98 and 29x -23y =110
(ii) 99x +101y =499 and 101x +99y =501

Answers

Answer:

23 x-29y=98.......(1)

29 x-23y=110.......(2)

adding (1) and (2)we get

52 x-52y=208

52(x+y)=208

x-y=4...(3)[we get four by dividing 208 with 52]

subtract (2) from (1) we get

-6 x-6y=-12

x-y=2.....(4)

adding (3) and (4) we get

2x=6

therefore x=3

now from (4) we get

x-y=2 [we substitute xfor 3]

3-y=2

y=2-3

y=-1( that is the answer for your first question)

Step-by-step explanation:

99x+101y=499.....(1)

101x+99y=501.....(2)

add (1) and (2)

(99+101)x+(101+99)=(499+501)

200x+200y=1000

200(x+ y)=1000

x+y=5.....(3)

subtract (2)from(1) we get

2x-2y=2

2(x-y)=2

x+y=1.......(4)

x+y=5

x-y=1(add them together)

2x=6

x=3

substitute x equal to 3 in equation (3)

x+y=5

3+y=5

y=2

y equal to 2 and x equal to 3

hope is not too late

3y - 21 = 12x
Help please

Answers

Simply
3Y+-21=12X

Re-order the terms
-21+3Y=12X

(Solving for Y variable)

Move all terms containing y to the left, all other terms to the right.

Add 21 to each side of the equation
-21+21+3Y=21+12X

Combine like terms: -21+21=0
0+3Y=21+12X
3Y=21+12X

Divide each side by 3
Y=7+4X

Simplifying
Y=7+4x

Step-by-step explanation:

The key take-away regarding what relation is or is not a function is the following: a function has no repeated x-values.

The x-values in the table are -3, -1, 0, 2, so any suggested ordered pair with one of those as an x-value cannot be added to the table. The only such pair in the list is the first one (-3, 4). It cannot be added. All of the remaining three pairs can be added and the relation will remain a function.

Find the median for the given set of data

⅝, ¾, 1⅛, 1¼

Answers

Answer:

15/16

Step-by-step explanation:

Put the data in the ascending order, first bring to common denominator:

5/8, 3/4 = 6/8, 1 1/8 = 9/8, 1 1/4 = 5/4 = 10/85/8, 6/8, 9/8, 10/8

Since the data is even the median is the average of 6/8 and 9/8:

(6 + 9)/8*1/2 = 15/16

Help........Betty wants to bake the perfect cookie. She wants to determine the ideal temperature at which to bake the cookies. She has enough batter to make 60 cookies. She decides to randomly assign 15 cookies to be baked at 300°, 15 at 325°, 15 at 350°, and 15 at 375°. The baking time for each batch is 12 minutes. Which statement about the randomization for the completely randomized design is correct? Betty should place the first 15 balls of cookie dough that she scoops from the batter on a tray, and those will be baked at 300°. The next 15 will be placed onto a second tray to be baked at 325°. She should continue in this manner until all 60 cookies have been placed on trays. Betty should scoop a ball of cookie dough from the batter, and then roll a die. Numbers 1–4 would indicate at which temperature the cookies will be baked, and 5–6 would indicate that she should roll again. She should repeat this process until all 60 cookies have been allocated. Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated. Betty should place the first cookie on a tray to be baked at 300°. The second cookie will go on a tray to be baked at 325°, the third will go on a tray to be baked at 350°, and the fourth will go on a tray to be baked at 375°. She will continue placing the cookies in this pattern until all 60 cookies are on trays to be baked.

Answers

Answer: Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.

Step-by-step explanation: I just got it correct on Edge :)

The true option about the randomized design is (c) Betty should prepare all 60 cookies. Each cookie will receive a number. The numbers will be written on slips of paper, put into a hat, and shuffled well. The first 15 numbers drawn will indicate the cookies to be baked at 300°, the next 15 will indicate the cookies to be baked at 325°, and so on until all 60 cookies are allocated.

The given parameters are:

[tex]\mathbf{n = 60}[/tex]

[tex]\mathbf{Batches = 4}[/tex]

[tex]\mathbf{Cookies= 15}[/tex] ---- the number of cookies in each batch

[tex]\mathbf{Temperature= 300,325,350,375}[/tex]

To randomly assign the cookies to the given temperatures, all cookies have to be subjected to the same conditions (except the difference in the temperature).

This means that, she can bake all the cookies at once at different temperatures, while noting down the cookies with a given number.

Hence, the true option is (c)

Answer:

3/5, 30%, 0.1

Step-by-step explanation:

0.4 + 1/2 + 40% = 0.4 + 0.5 + 0.4 = 1.3

3/4 + 0.25 + 1/2 = 0.75 + 0.25 + 0.5 = 1.5

3/5 + 30% + 0.1 = 0.6 + 0.3 + 0.1 = 1

Well since both angles equal a right triangle (90 degrees) you would set up the equation 90=2x+3x+5

90=2x+3x+5
85=5x
17=x

and to find the angles, just plug in x which is 17

John belongs to a boating club that rents sailboats for $60 for the first hour and $20 for each additional hour. After renting a boat one day, he owed the boating club a fee of $140.

Write and solve an equation to find how many hours he kept the boat.

Answers

Answer:

4 Hours

Step-by-step explanation:

The original boating fee is $60 then you add $20 per hour so 20 x 4 = 80

80+60=140 $140

Answer: 140=60+20x. He kept the boat for 4 hours

Step-by-step explanation:

x=hours

y=final cost and the final cost is $140

to find x you would use the equation: 140=60+20x

you would first subtract 60 from both sides and you would get:

80=20x

Now you would divide 20 from both sides

So x is 4
