Good luck, i’m not sure what this is but like my comment and i’ll come back to it when i get my notes
Substitute value of y from equation (1) in equation (2),
5x-4(5-3x) = -3
5x-20+12x = -3
17x=17
x = 1
Substitute it in equation (1),
y = 5-3(1)
y = 5-3 = 2
So, the values (x,y) = (1,2)

is our fraction, which is not in lowest form, and therefore can be reduced. We can divide both numerator and denominator by 2, and we end up with

7 goes into 14 twice, so we can reduce it further to become

To convert a fraction to a ratio, you just need to turn it on its side and make the | into a : So it would look like this:
1:21 / 2 = 0.5

0.5 is the fraction in decimal formTo find a percentage, you just need to multiply the decimal by 100.
0.5 in percentage form would be 50%
Hope that helped =)

Answer:</h3>
60%
<h3>
Step-by-step explanation:</h3>
The percent change can be found from ...
... ((new value)/(old value) -1) × 100%
... (1520/950 -1) × 100% . . . . . . filling in your numbers
... (1.6 - 1) × 100% = 60% . . . . . . simplify
