Only when any equation you find among those numbers can be simplified into one of the four main equations, wich means you only have four different true statements, and lots of equivalences.

Solve -44-7k=12+k answer quick please
nirvana33 [79]

Answer:

k = -7

Step-by-step explanation:

Solve for k:

-7 k - 44 = k + 12

Subtract k from both sides:

(-7 k - k) - 44 = (k - k) + 12

-7 k - k = -8 k:

-8 k - 44 = (k - k) + 12

k - k = 0:

-8 k - 44 = 12

Add 44 to both sides:

(44 - 44) - 8 k = 44 + 12

44 - 44 = 0:

-8 k = 12 + 44

12 + 44 = 56:

-8 k = 56

Divide both sides of -8 k = 56 by -8:

(-8 k)/(-8) = 56/(-8)

(-8)/(-8) = 1:

k = 56/(-8)

The gcd of 56 and -8 is 8, so 56/(-8) = (8×7)/(8 (-1)) = 8/8×7/(-1) = 7/(-1):

k = 7/(-1)

Multiply numerator and denominator of 7/(-1) by -1:

Answer: k = -7

Answer:

y = 1500 * 1.09^t

Step-by-step explanation:

\text{It should be clear that the rate of change is non-linear}\text{, meaning that we can express the function in the following manner}

\text{y = a * b^t, where a is the initial value and b is the rate of change and t is how}y = a * b^t, \text{where a is the initial value and b is the rate of change and t is how many years.}

\text{Well, year 0 is the rate of change so we can say that a = 1500}

\text{Next, we divide any two consecutive year balances to find our rate of change:}

1635/1500 = 1.09

\text{Therefore, our equation looks like this:}

y = 1500 * 1.09^t

nevsk [136]

Answer:

4 more strips

Step-by-step explanation:

Given that:

Length per strip = 1/6

Fraction of paper left = 2/3

Number of strips that can be cut from the Fraction left ;

Fraction left ÷ length per strip

2/3 ÷ 1/6

2/3 * 6/ 1

(2 * 6) / (3 * 1)

12 / 3

= 4
