either 8 or 4

Step-by-step explanation:

because it can't be 6 or 5

The correct reason for each step in the solution of the equation would be as follows:

12 − 5x + 6x = 4 - Given

12 + x = 4 - Combine Like Terms

x= −8 - Subtraction Property of Equality

Answer:

EF=6

Step-by-step explanation:

E is the midpoint, so DE = EF

DE = 15-3x

EF = x+ 3

Since DE = EF,

15 - 3x = x + 3

-4x = -12

x = 3

If x = 3,

DE = 15 - 3*3,   15 - 9 = 6

EF = x+ 3, so EF = 3 + 3 = 6

Answer:

the error(s) is from the step 2

Step-by-step explanation:

3r - 12 = 2r - 3  +4r

3r - 4r -2r = 12 - 3

-3r = 9

r = 9 : (-3)

r = -3

--------------------------

the error(s) is from the step 2

The interest earned in five years is $1400.

Simple interest is interest calculated on the principal portion of a loan or the original contribution to a saving account.

A = P(1 + rt)

Where,

A is the final amount

P is the initial principal balance

r is the annual interest rate

t is time(in years)

According to the given question

We have

Initial Principal balance, P = $7000

Time, t = 5years

Annual interest rate, r = 4% = 0.04

Therefore, the amount in five years is given by

A =  7000(1 + 0.04(5))

A = 7000(1 + 0.2)

A = 7000(1.2)

A = $8400

Now, the interest earned in five years

S.I = A - P

⇒ S.I = $8400 - $7000

⇒ S.I = $1400

Hence, the interest earned in five years is $1400.

Answer:

16 times

Step-by-step explanation:

Membership cost:

C = 135 + 2x

Non-members:

C = 11x

____

135 + 2x = 11x

135 = 9x

x = 15

The cost would be the same after renting 15 times, so after 16 times the cost would be cheaper for a member.

The percentage error in the deer population is 17%

Actual population = 21300

Estimated population = 17600

The percentage error will be calculated by subtracting the estimated population from the actual population and then dividing the result. This will be:

= (Actual population - Estimated population) / Actual population × 100

= (21300 - 17600) / 21300 × 100

= 3700/21300 × 100

= 0.17 × 100

= 17%

Therefore, the percentage error in the deer population is 17%

I'm not sure about the first one on question 5 though.

deu ruim  aqui pq eu não sei

Step-by-step explanation:

Answer:

Simplifying

4x + -6 = 2(2x + 3)

Reorder the terms:

-6 + 4x = 2(2x + 3)

Reorder the terms:

-6 + 4x = 2(3 + 2x)

-6 + 4x = (3 * 2 + 2x * 2)

-6 + 4x = (6 + 4x)

Add '-4x' to each side of the equation.

-6 + 4x + -4x = 6 + 4x + -4x

Combine like terms: 4x + -4x = 0

-6 + 0 = 6 + 4x + -4x

-6 = 6 + 4x + -4x

Combine like terms: 4x + -4x = 0

-6 = 6 + 0

-6 = 6

Solving

-6 = 6
