Answer:

x=-6

Step-by-step explanation:

Use Substitution

so 5-2x=-4x-7

I'ma move that -4x to the other side by making it a positive

5+2x=-7

than I'ma move that 5 to the other side by making it a negative

2x=-12

to isolate the x you dived by both sides by the 2

x=-6

I doubled checked and it's -6

Answer:

Pull out like terms: 12 + 2x = 2 • (x + 6)

Solve: x+6 = 0

Then you get; X=-6

I hope this is right and hopefully it helped you

Total number of faculty is 136. There are 6 professors to every 11 lecturers. How many professors are there
laila [671]

Answer:

The Total number of Professors = 48  

Step-by-step explanation:

Given as,

The total number of Faculty = 136

And the Ratio of Professors to Lecturers = 6 Ratio 11

Now According to question

Professors : Lecturers = 6 : 11

So, Let the Number of Professors = 6x

And      The Number of Lecturers = 11x

∴ 6x + 11x = 136

  Or,   17x = 136

   Or,      x = \frac{136}{17} = 8

Hence, the number of Professors = 6 × 8 = 48       Answer

Maslowich

Answer:

Step-by-step explanation:

it is 0.5 since

y=25(0.5)x

since x is a variable that change usually describes the independent variable, and 25 is the sample that starts with, so 0.50 is the number that represent the decayed rates.

Use the work shown to find the solutions of the quadratic equation. x2 – x –3/4=0 x2 – x = 3/4
bija089 [108]

Answer:

x = - \frac{1}{2}, x = \frac{3}{2}

Step-by-step explanation:

Given

x² - x - \frac{3}{4} = 0

Multiply through by 4 to clear the fraction

4x² - 4x - 3 = 0

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 4 × - 3 = - 12 and sum = - 4

The factors are + 2 and - 6

Use these factors to split the x- term

4x² + 2x - 6x - 3 = 0 ( factor the first/second and third/fourth terms )

2x(2x + 1) - 3(2x + 1) = 0 ← factor out (2x + 1) from each term

(2x + 1)(2x - 3) = 0

Equate each factor to zero and solve for x

2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - \frac{1}{2}

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = \frac{3}{2}

Question 2:
Helga [31]

Answer:

15mins

Step-by-step explanation:

Given that he worked out a total of 360mins, and jogged 45mins/day:

Jog \ Time=Total \ Time- Bike \ Time\\=360-(45\times6)\\=90min

Therefore, Allen jogged a total of 90mins in the past one week. To calculate the time jogged each day, we divide the total jog time by number of days jogged:

t_d=Total \Time/(No \of \ Days)\\=90/6\\=15mins

Allen jogged 15mins per day.
