25.3%
you have to do 4.06-3.24
then do that number divided by the original number then times by 100
Answer:
true
Step-by-step explanation:
5x + 4x = 9x
3y + 7y = 10y
8 + 34 = 42
System of equations:
x + y = 23
x - y = 7
Add them together
2x = 30
x = 15
Now plug 15 into one of the equations:
15 + y = 23
y = 8
your two numbers are 15 and 8
Please help much appreciated
