Answer:
Step-by-step explanation:
If BOTH equations are in slope-intercept form then the-graphing-? method would be best, but the-substitution-? method would also be effective since both y's are already by itself.
If ONE of the equations is solved for x or y and the other equation is not, then the-substitution-? method is best.
If BOTH equations are lined up in standard form & the coefficients of x or y are opposites then the BEST method is definitely the-elimination--? method.
If BOTH equations are lined up in standard form the elimination method would be best. But if the coefficient of x or y is 1, then the-substitution--? method is also effective.
Insert 80 into the equation
1(80) / 5
80/5 = 16
B because it u and 9 friends each want the same amount from splitting 1.30 which gives you .13
It’s 50/50 hope this helps
8x40=320 (+) 8x7=56 (=) 376.
A=40
hope this helped
