I use the substitution method, but you can also use elimination and matrix
1. Solve for y in 3x+y=14
y=14-3x
2. Substitute y=14-3x into x+2y=3
-5x+28=3
3. Solve for x in -5x+28=3
x=5
4. Substitute x=5 into y=14-3x
y=-1
5. Therefore,
x=5
y=-1
Have a nice day :D
Answer:
equals 800
Step-by-step explanation:
10 x 10 x 8
you would multiply
The missing exponent is 2
Answer:
yes because when you multiply 3000 by 10 that gives you a total of 30000 that you paid off
25 * 5 + 15 * 3 - 40 * 2 =
125 + 45 - 80 =
170 - 80 =
90
