Kent multiplies both sides of the equation below by an expression.

2 answers:

8 0

The steps below are presented in order to arrive to the value of k of the given equation.
First, multiply both sides of the equation by the variable k since the left-hand side of the equation has it in the denominator. This will be,
(k + 12/ k)(k) = 8(k)

Then, we simplify,
k + 12 = 8k
We then, subtract 8k to both sides of the equation,
k - 8k + 12 = 8k - 8k

Simplifying,
-7k + 12 = 0

Then, subtract 12 from both sides of the equation and divide both sides by -7. This will us the final answer of,
k = 12/7

I have a 3 foot board that needs to be equally decided into 1/2 how many extra peices will I have

anygoal [31]

Answer:

No extra pieces.

Step-by-step explanation:

Given:

Total number of foot board = 3

Equally divided into = 1/2

Question asked:

How many extra pieces will I have = ?

Solution:

By dividing 3 by 1/2 we can find the extra pieces.

= $3\div\frac{1}{2}$

= $3\times\frac{2}{1}$

= $6$

Since, the remainder is zero, thus there is no any extra pieces I have.

The sum of two numbers is 95. If the larger is increased by twice the smaller, the result is 120. Find the numbers.

adelina 88 [10]

Hello!

You can make two expressions based on what you know

let x equal the larger number
let y equal the smaller number

x + y = 95
x + 2y = 120

We can use elimination to get rid of x

You can subtract the two equation to get rid of x

-y = -25

Since y is negative we can multiply both sides by -1 to make y positive

y = 25

Now we can put this into one of the other equations to find x

x + 25 = 95

subtract 95 from both sides

x = 70

The answers are 70 and 25

Hope this helps!

Item 9 a flight averages 460 miles per hour. the return flight averages 500 miles per hour due to a tailwind. the total flying t

Ksenya-84 [330]

Let us say that the variables for flight is designated by 1, while the return flight by 2, since the distance travelled are equal, therefore:

v1 t1 = v2 t2

460 t1 = 500 t2

Since t1 + t2 = 4.8, therefore: t1 = 4.8 – t2

460 (4.8 – t2) = 500 t2

2208 – 460 t2 = 500 t2

960 t2 = 2208

t2 = 2.3

t1= 4.8 – t2 = 4.8 – 2.3

t1 = 2.5

Answer:

The flight took 2.5 hours while the return flight took 2.3 hours.
