Mathematics

Schach [20]4 years ago

7 0

let those numbers be x and y

According to your question

x + y = -7

x - y =14

adding both equations

2x = 7

or x = 7/2

substitute value of x in either equation

y = -21/2

So,

x= 7/2

y=-21/2

Hope this helps!

Thanks

35% of salt is in feta cheese. What percentage of salt is in that 350 g cheese?

xxMikexx [17]

The amount of salt is in the 350 g of feta cheese, when there is 35% of salt is in cheese, is 122.5 grams.

<h3>What is percentage of a number?</h3>

Percentage of a number is the part of the whole number which is expressed in the fraction of hundredth. It is represented with "%" symbol.

35% of salt is in feta cheese. The percentage of salt is in that 350 g cheese has to be found out.

Let suppose there is x grams of slat in feta cheese of 350 g. Thus, the amount of salt (35% of 350) is,

$x=\dfrac{35}{100}\times350\\x=122.5\rm\; gm$

Thus, the amount of salt is in the 350 g of feta cheese, when there is 35% of salt is in cheese, is 122.5 grams.

The perimeter of a rectangle is 24 feet. The length is 3 feet less than twice the width. Which of the following systems would be

Temka [501]

the answer would be, "The width is" all of the other information is neccesary!! You could not solve the problem without knowing what the the toal is and what the length is!! You need that info. So "the width is" is not important cuz if you were to take 24 and divide it by 3 * 2 you would have the width.

What is the distance, to the nearest whole number, from K(5,6) to P(1,-4)

yarga [219]

Answer:

The distance between the two points is approximately 11 units

Step-by-step explanation:

Here, we are to give the distance between the given two points to the nearest whole number;

To calculate the distance, we shall be using the distance formula;

D = √(x2-x1)^2 + (y2-y1)^2

(x1,y1) = (5,6)

(x2,y2) = (1,-4)

D = √(1-5)^2 + (-4-6)^2

D = √((-4)^2 + (-10)^2

D = √(16+100)

D = √(116)

D = 10.77 units which is approximately 11 units
