Find X And Y.

Answers

Answer 1

[tex]\\ \sf\longmapsto 2x+11=3x-9[/tex]

[tex]\\ \sf\longmapsto x=11+9[/tex]

[tex]\\ \sf\longmapsto x=20[/tex]

And

[tex]\\ \sf\longmapsto y+10=2y-40[/tex]

[tex]\\ \sf\longmapsto 2y-y=10+40[/tex]

[tex]\\ \sf\longmapsto y=50[/tex]

Answer 2

Step-by-step explanation:

x

2x + 11 = 3x - 9

2x - 3x = -9 - 11

x = -20

[tex] \: [/tex]

y

y + 10 = 2y - 40

y - 2y = -40 - 10

-y = -50

y = 50

Find the term of the arithmetic sequence in which a 27=-1/2 and the common difference is 2.

Answers

Step-by-step explanation:

arithmetic sequence means that every new term is created by adding a certain constant (here 2) to the previous term.

a27 = -1/2 = a1 + (n-1)×2 = a1 + 26×2 = a1 + 52

a1 = -52 1/2 = -105/2

an = -105/2 + (n-1)×2

In an equilateral triangle all the sides are equal. This means that all the angles add up to 180 degrees.
Divide 180 by 3 and you get 60.
You want an exterior angle so you cut the angle in half ( it is now 30 )
Because the base and the line are parallel (form right angle if drew line connecting them) x is equal to
90-30=60

-5x-9y=2
elimation

Answers

Answer:

Step-by-step explanation:

We know x=2y=-1

So -5x-9y=2

<=> -5(1) +(-4)(1) - (y) =2

<=> -9- (y)=2

<=> y=-9-2

<=> y=-11

P/s: -9y= -8y-y = -4x-y = (-4)(1)-y

or,x/3-2<4

or,x/3<4+2

or,x<6/3

or,x<2

Answer:

x < 18

Step-by-step explanation:

You solve it like an equation.

First, isolate the x-value to one side by adding 2 to each side:

x/3 - 2 + 2 < 4 + 2

The twos on the left side cancel out:

x/3 < 6

Now multiply both sides by 3:

x/3 x 3 < 6 x 3

The threes on the left side cancel out, leaving you with the x-value:

x < 18

Hope this makes sense :)

Answers

Answer:

50²-48²

solve it you will get answer

Answer:

C) 14

Step-by-step explanation:

(Phytogoras theorem)

[tex] {50}^{2} = {48}^{2} + {x}^{2} [/tex]

2500 = 2304 + x^2

2500 - 2304 = x^2

X^2 = 196

Which is the solution to the system of equations? (1 point)

Group of answer choices

(−2, −1)

(−2, 1)

(−1, −2)

(1, −2)

Answers

Answer:

(1, −2)

Step-by-step explanation:

−3x + 1 = 2x − 4

−5x + 1 = − 4........subtract 2x from both sides

-5x = -5.................subtract 4 from both sides

x  = 1.......................divide both sides by - 5

now that you have x value find y by plugging in the x value in either one of the equations (I'll be using y = -3 +1)

y = -3(1)+1

y = -3+1.............multiply

y = -2................add

To find a common denominator, you have to find a number that is a multiple of all the denominators there. So with 240, 240 divide 3 is 80, so that's a multiple, 240 divide 8 is 30, so that is also a common multiple, and 240 divide 10 is 24, so that is also a common multiple.

rearranging formulae y=4x+3

Answers

Step-by-step explanation:

y = 4x + 3

subtract 3 on both sides of equation

y - 3 = 4x + 3 - 3

y - 3 = 4x

divide the equation by 4 on both sides

\frac{y - 3}{4} = \frac{4x}{4}4y−3=44x

x = \frac{y - 3}{4}4y−3

9. Allen and his two brothers decide to purchase a video game system together. They determine
that each person will need to pay $32.30. How much is the cost of the video game system?
I need a variable, equation, and the solution. Pls help!!!

Answers

Step-by-step explanation:

that is so simple, it is already difficult to make it formal, because there are only so few things to deal with. you really need help with this ?

you are not familiar with the situation "hey, this costs $10, we are 5 people, if we buy and then use it together, each one has to pay $2" ?

and this is just the other way around : if 5 people paid $2, how much did they pay together ? $10.

let's make it super formal :

price p = Allen contribution a + brother1 contribution b + brother2 contribution c

p = a + b + c

a = b = c = $32.30

p = $32.30 + $32.30 + $32.30 = 3×$32.30 = $96.90
