Answer:
x= 0.083 y = 0.5
Step-by-step explanation:
step 1:
equation 1: 6x -y
equation 2 : 4y = 2
from equation (2) 4y = 2, we calculate value of y to get x
4y = 2 ... divide both sides by 4
<u>4y </u>= <u>2</u>
4 4 y = 1 /2. y = 0.5
Step 2:
input the value of y into the equation 1 to get x.
6x - y = 0
6x - 0.5 = 0
6x- 0.5 + 0.5 = 0 + 0.5 ( Add both sides of the equation by 0.5)
6x = 0.5.... divide both sides of the term by 6
<u>6x </u>= 0.5
6 6
x = 0.083
therefore, y = 0.5 and x = 0.0833
Answer:
6
Step-by-step explanation:
Hello. To answer this questions, we need to remember some properties about fractions and equivalences.
Starting by the question 9:
Call the population 5 years ago by P. If the population has decreased 12000 in these 5 years and this represents a decrease of 3%, so it means the new population is 0.97P.
With this, we can make the following equation:
P - 12000 = 0.97P
Subtract 0.97P and sum 12000 in both sides of the equation
0.03P = 12000
Divide both sides of the equation by a factor of 0.03
P = 3600000
A fraction equivalent to 9/15 is 3/5
To find equivalent fractions, you have to find a a divisor that both the numerator and denominator has. Then you divide the numerator and denominator by that divisor.
Example: 9 and 15 are divisible by 3.
9 is the numerator.9 divided by 3 is 3. so the numerator of the equivalent fraction is now 3.
15 is the denominator. 15 divided by 3 is 5. the denominator is now five.
Hope this helps! :)
