M + w = 253m + 4w = 90 Let's do substitution, first by solving the first equation for m. m = 25 - w Substitute! 3(25 - w) + 4w = 9075 - 3w + 4w = 90w = 15 m = 25 - 15 = 10 Hope this helps!
Answer:
a^3-b^3
Step-by-step explanation:
(a−b)(a2+ab+b2)
=(a+−b)(a2+ab+b2)
=(a)(a2)+(a)(ab)+(a)(b2)+(−b)(a2)+(−b)(ab)+(−b)(b2)
=a3+a2b+ab2−a2b−ab2−b3
=a3−b3
Answer:
1/2
Step-by-step explanation:
were gonna need some formula that deals with slope and points. I'm thinking the point slope formula. y2-y1=m(x2-x1) so 10-7=m(-1+7) solve for m so 3=m(6) so m=3/6 or reduce to m=1/2
