Let 27 be x% of 60

so,
x/100 *60 = 27
x = 27*100/60 = 270/6 = 45

So,
27 is <em>45%</em> of 60.

Which of the following are solutions?

zloy xaker [14]

This is a quadratic equation. There's a shortcut (two shortcuts really) called the Shakespeare Quadratic Formula (2b or -2b) applicable when the middle term is even:

$x^2 - 2bx + c \textrm{ has zeros } x= b\pm \sqrt{b^2-c}$

$ax^2 - 2bx + c \textrm{ has zeros } x= \dfrac 1 a( \left b\pm \sqrt{b^2-ac} \right)$

OK, our problem is

$9x^2 - 6x -7 = 0$

$x = \frac 1 9 (3 \pm \sqrt{9-(9)(-7)}) = \frac 1 9(3 \pm \sqrt{72})= \frac 1 9(3 \pm 3 \sqrt{8}) = \frac 1 3(1 \pm \sqrt 8)$

Typically we'd write $\sqrt 8 = 2 \sqrt 2$ but the answers here don't so we won't either.

A construction team gives an estimate of three months to repave a large stretch of a very busy road with their core crew of 9 pe

Licemer1 [7]

Answer:

Step-by-step explanation:

9 crew members complete a job in 3 months

Number of crew members is inversely proportion to construction time :

Let :

Crew members = m

Construction time = t

m α 1 /t

m = k/t

m = 9 ; t = 3

9 = k /3

k = 27

If t = 1 (one month)

m =?

m = k/t

m = 27 / 1

Hence;

m = 27 * 1

m = 27 workers

2(x+11) = -26 show all work pls

Degger [83]

Answer:

x = -24

Step-by-step explanation:

First, distribute 2 to all terms within the parenthesis:

2(x + 11) =

2 * x = 2x

2 * 11 = 22

2x + 22 = -26

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. PEMDAS is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Divisions

Additions

Subtractions

First, subtract 22 from both sides of the equation:

2x + 22 (-22) = -26 (-22)

2x = -26 - 22

2x = -48

Next, divide 2 from both sides of the equation:

(2x)/2 = (-48)/2

x = -48/2

x = -24

x = -24 is your answer.
