Answer:

X=-6

Step-by-step explanation:

4(1−x)+3x=−2(x+1)

(4)(1)+(4)(−x)+3x=(−2)(x)+(−2)(1)(Distribute)

4+−4x+3x=−2x+−2

(−4x+3x)+(4)=−2x−2(Combine Like Terms)

−x+4=−2x−2

Step 2: Add 2x to both sides.

−x+4+2x=−2x−2+2x

x+4=−2

Step 3: Subtract 4 from both sides.

x+4−4=−2−4

x=−6

Answer:

x=−6

Over the course of a month, Katniss caught three times as many squirrels as deer. She also caught five less rabbits than squirre

natta225 [31]

Answer:

10 rabbits

Step-by-step explanation:

Let us represent

Number of rabbits = x

Number of squirrels = y

Number of deer = z

Katniss caught three times as many squirrels as deer.

y = 3z

She also caught five less rabbits than squirrels.

y = x - 5

The total number of animals she caught is ten more than four times the number of deer caught.

x + y + z = 4 × z + 10

x + y + z = 4z + 10

How many rabbits did Katniss catch?

Number of rabbits = x

We make x subject of the formula

x + y + z = 4z + 10

x = 4z + 10 - y - z

y = 3z

x = 4z + 10 - 3z - z

x = 4z - z - 3z + 10

x = 4z - 4z + 10

x = 0 + 10

x = 10

Therefore, the number of rabbits Katniss caught is 10 rabbits

Answer:

Option C $3n^{2}+n-2$

Step-by-step explanation:

<u><em>Verify each expression</em></u>

case A) we have

$5n^{2}+6n-1$

In this expression the term of n is 6n

has a coefficient of positive 6

case B) we have

$2n^{2}-5n+1$

In this expression the term of n is -5n

has a coefficient of negative 5

case C) we have

$3n^{2}+n-2$

In this expression the term of n is n

has a coefficient of positive 1

case D) we have

$4n^{2}-n+9$

In this expression the term of n is -n

has a coefficient of negative 1
