Answer:

(-3,5)

Step-by-step explanation:

4x + 3y = 3

x − 3y = −18

Solve by addition/Elimination

x = -3

y = 5

So,

The solution of the system is (-3,5).

Answer: x = 4 , y = 6

Step-by-step explanation:

4 x = 3 y − 2  ,  18 = 3 x + y

Solve for  y

in the second equation.

Tap for more steps...

4 x = 3 y − 2 y = 18 − 3 x

Replace all occurrences of  

y  in  4 x = 3 y − 2

with  

18 − 3 x . 4 x = 3 ( 18 − 3 x ) − 2 y = 18 − 3 x

Simplify  

3 ( 18 − 3 x ) − 2  

Tap for more steps...

4 x = − 9 x+ 52 y = 18 − 3 x

Move all terms in  

4 x = − 9 x + 52

to the left side and simplify.

Tap for more steps...

13 x − 52 = 0 y = 18 − 3 x

Solve for  x

in the first equation.

Tap for more steps...

x = 4 y = 18 − 3 x

Replace all occurrences of  

x  in  y = 18 − 3 x

with  4 . x = 4 y = 18 − 3 ⋅ 4

Simplify  

18− 3 ⋅ 4  

Tap for more steps...

x = 4 y = 6

The solution to the system of equations can be represented as a point.

( 4 , 6 )

The result can be shown in multiple forms.

Point Form:

( 4 , 6 )

Equation Form:

x = 4 , y = 6

What value ofx is in the solution set of 3(x-4)&gt;5x +2?
kvv77 [185]

\boldsymbol{\sf{3(x-4) > 5x +2 }}

Use the distributive property to multiply 3 by x−4.

\boldsymbol{\sf{3x-12 > 5x+2 }}

Subtract 5x on both sides.

\boldsymbol{\sf{3x-12-5x > 2 } }

Combine 3x and −5x to get −2x.

\boldsymbol{\sf{-2x-12 > 2 }}

Add 12 to both sides.

\boldsymbol{\sf{-2x > 2+12 \ \longmapsto \ \ [Add \ 2 +12]}}

\boldsymbol{\sf{-2x > 14}}

Divide both sides by −2. Since −2 is < 0, the inequality direction is changed.

\boldsymbol{\sf{x < \dfrac{14}{-2} \ \ \longmapsto \ \ \ [Split]}}

\boxed{\boldsymbol{\sf{x < -7 }}}

So in the <u>inequality 3(x-4)>5x +2</u>, the value of x is -7.

Pippa had 35 stickers.
Ivan

Answer: 3 stickers

Step-by-step explanation:

From the question, we know that Pippa's 8 friends have an equal amount of stickers, meaning that the number of stickers that Pippa gave out is a multiple of 8.

Also, we are able to know that Pippa gave as much as she can, meaning that she gave out the stickers until the number is the maximum multiple of 8.

First Five Multiple of 8 = 8, 16, 24, 32, 40

As we can see from the list, 8, 16, and 24 are all multiples of 8, but they are not the maximum number that could fit under 35 stickers. Similarly, 40 exceeds the number of stickers Pippa has. Thus, we are left with 32.

This means, Pippa gave out 32 stickers in total, and each friend got 4 stickers.

  • 32 / 8 = 4 stickers

Also, this means Pippa would keep <u>3 stickers</u> for herself.

  • 35 - 32 = 3 stickers

Hope this helps!! :)
