= -3^2 - 5(-3) + 3

= -9 - (-15) + 3

= -9 + 15 + 3

= 6 + 3

= 9

Answer: 9

L is between M and N. If NL = 5x, LM = 3x, and NL = 15, find x.

Leona [35]

Answer:

x = 5

Step-by-step explanation:

Given that,

NL = 5x, LM = 3x, and NL = 15

L is between M and N.

To find,

The value of x.

Solution,

It is mentioned that, L is between M and N. So,

LM = LN

Put all the values,

3x = 15

⇒ x = 5

So, the value of x is equal to 5.

10kg 20kg 24kg ?kg plz answer this for me

luda_lava [24]

Answer:

27KG

Step-by-step explanation:

Mouse- M , Cat - C, Dog - D

M + C = 10 ----- (1)

M + D = 20 -------(2)

C + D = 24 --------(3)

(1) - (2) => C - D = -10 ---- (4)

(3) + (4) => 2C = 14

=> C = 7

Substitute C in (1) => M + 7 = 10

=> M = 3

Substitute M in (2) => 3 + D = 20

=> D = 17

Therefore C + M + D = 7 + 3 + 17 = 27KG

Solve this system of linear equations. separate x and y values with a comma. 7x=-67-11y 5x=-73-11y

Aleks [24]

Answer:

3, -8

(x is equal to 3 and y is equal to -8)

Step-by-step explanation:

The system:

{ 7x=-67-11y

{ 5x=-73-11y

Finding a value for x:

7x=-67-11y -> x = $-\frac{67}{7}$ - $\frac{11y}{7}$

Solving for y by plugging in our x:

[Equation] 5x = -73 -11y

[Plug-in] 5( $-\frac{67}{7}$ - $\frac{11y}{7}$ ) = -73 -11y

[Distribute the 5] $-\frac{335}{7}$ - $\frac{55y}{7}$ = -73 -11y

[Multiply by 7] 7 ( $-\frac{335}{7}$ - $\frac{55y}{7}$ ) = (-73 -11y) 7

[Simplify] -335 - 55y = -511 - 77y

[Add 335 and 77y to both sides] 22y = -176

[Divide by 22] y = -8

Plug in our y to solve for x:

5x = -73 -11y

5x = -73 -11(-8)

5x = -73 + 88

5x = 15

x = 3

Have a nice day!
