Please solve with answers! thanks.<br> n/5 +0.6=2

Maslowich

N/5 + 0.6=2
We simplify the equation to the form, which is simple to understand n/5 + 0.6=2
We move all terms containing n to the left and all other terms to the right. + 0.2n=+2-0.6
We simplify left and right side of the equation. + 0.2n=+1.4
We divide both sides of the equation by 0.2 to get n. n=7

The distance between two cities is 87 km. What is the distance between them on a map drawn at a scale of 1:600,000?

Alexxx [7]

Answer:

<u>The correct answer is 14.5 centimeters on the map would be the distance between these two cities.</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Distance between two cities = 87 kilometers

Scale of the map = 1:600,000

2. What is the distance between them on a map with that scale?

For finding out the answer to this question, we need to:

A. Convert 87 kilometers to centimeters, that is the average distance measurement of the maps, this way:

87 kilometers = 87,000 meters (multiplying by 10³)

87,000 meters = 8'700,000 centimeters (multiplying by 10²)

B. Now we divide the measurement in centimeters by the scale, this way:

8'700,000/600,000 = 14.5

<u>The correct answer is 14.5 centimeters on the map would be the distance between these two cities.</u>

My brainy brother and sister added their ages together and got 15. When they multiplied their ages together, they got 54. How ol

Vinvika [58]

Given:

Sum of ages of brother and sister = 15

Product of their ages = 54

To find:

How old is the older one between the two of them?

Solution:

Let x be the age of brother and y be the age of sister.

Sum of ages of brother and sister = 15

$x+y=15$

$x=15-y$ ...(i)

Product of their ages = 54

$xy=54$

$(15-y)y=54$ [Using (i)]

$15y-y^2=54$

$0=54-15y+y^2$

Splitting the middle term, we get

$54-15y+y^2=0$

$54-9y-6y+y^2=0$

$9(6-y)-y(6-y)=0$

$(6-y)(9-y)=0$

Using zero product property, we get

$(6-y)=0\text{ and }(9-y)=0$

$y=6\text{ and }y=9$

If $y=6$ , then using (i), we get

$x=15-6$

$x=9$

If $y=9$ , then using (i), we get

$x=15-9$

$x=6$

Therefore, the age of older one is 9, the age of younger one is 6 and the difference between their ages is 3.
