think about two numbers that will get 25:
think about two numbers that will get 10
use the 5 times tables
5*5= 25
Use 5+5= 10
x^2+10x-25= 0
(x+5)(x+5)= 0
x+5= 0 , x+5= 0
x+5-5= 0-5
x= -5
x+5-5= 0-5
x= -5
Answer :
only x= 5
0.08x + 0.03y = 345, and to solve for each x and y, you can use the substitution method.
19. No
20. No
21. Yes
23. 1.8 miles
Step-by-step explanation:
A1=8
A2=A1+5 plug 8 into A1 here. After getting the value, put into next equation. And repeat until you get A5
A3=A2+5
A4=A3+5
A5=A4+5
