What is
2(3x + 4) = -28

Answers

Answer:

x= 10/3

or

x= 3.334

Depending on simplified form asked.

Step-by-step explanation:

6x +8 =28

subtract 8 from both sides

6x = 20

divide by 6

x=20 /6

x= 10/3 or x =3.334

if you like my answer, please mark me brainliest !! thanks !! <3

x = -6
2(3x + 4) =-28
divide both sides by 2
2(3x+4)/2 = -28/2
after dividing its 3x + 4 = -14
subtract 4 from both sides
3x + 4 - 4 = -14 - 4
after subtracting its 3x = -18
divide 3 from both sides
3x/3 = -18/3
x = -6

Creflo is 6 years older than Dean.
Raheem is twice as old as Creflo.
The sum of their ages is 34.
Work out the ratio of Dean's age to Creflo's age to Raheem's age.

Answers

C = D + 6
R = 2C
D + C + R = 34

R = 2 (D+6)
R = 2D + 12

D + (D + 6) + (2D + 12) = 34
Add like terms.

4D + 18 = 34
4D = 34 - 18
4D = 16
D = 4

C = D + 6
C = 4 + 6
C = 10

R = 2C
R = 2(10)
R = 20

Write as ratio.
D:C:R
4:10:20

Write an equation in slope-intercept form for the line passing through the two points (0,-2) and (3,0)

Answers

Answer:

y = (2/3)x - 2

Step-by-step explanation:

This problem is interesting in that both the x- and the y-intercepts are given.  The y-intercept is (0, -2), and so 'b' in 'y = mx + b' must be -2:

y = mx - 2.  The x-intercept is (3, 0), so we know that y = 0 when x = 3:

0 = m(3) - 2

This latter result must be solved for m:  3m = 2, or m = 2/3.

Then the desired equation is y = (2/3)x - 2.

The population of a place was 56000. Next 5 years it is expected to rise by 50%. What will be the population in next 5 years?

Answers

Answer:

84000 people

Step-by-step explanation:

So next 5 year wil be 56000 + 50%

56000 = 100%

50% = 56000 / 2

50% = 28000

56000 + 28000 = 84000
