Answer:
130
Step-by-step explanation:
10+10+5+5=30
50+50=100
30+100=130
For lesson 4 10^15/10^4= 10^11 because when you are dividing with exponents you have to subtract the bottom exponent with the top one so 15-4=11; 10^15/10^4=10^11
Answer:
2x + 3y = -6
-4x + 3y = 12
5x + 3y = }
x - y = 5
Step-by-step explanation:
Standard Form is
.
2x + 3y = -6, -4x +3y = 12, 5x + 3y = '?', and x - y = 5 are the equations that are in standard form.
'2x+3 = 6' does not have the 'y' to make it standard form.
'y = 2x + 5' is slope-intercept form.
