Whatas the answer to 12.6+4m=9.6+8m

SVEN [57.7K]

Answer:

$\large\boxed{m=\dfrac{3}{4}=0.75}$

Step-by-step explanation:

$12.6+4m=9.6+8m\qquad\text{subtract 12.6 from both sides}\\\\12.6-12.6+4m=9.6-12.6+8m\\\\4m=-3+8m\qquad\text{subtract}\ 8m\ \text{from both sides}\\\\4m-8m=-3+8m-8m\\\\-4m=-3\qquad\text{divide both sides by (-4)}\\\\\dfrac{-4m}{-4}=\dfrac{-3}{-4}\\\\m=\dfrac{3}{4}=0.75$

4.2(3.9r – 5.9s) + 7.9s – 9.53r

nexus9112 [7]

Answer:

D. 6.85r – 16.88s

Step-by-step explanation:

Use the distributive property to eliminate parentheses, then collect terms.

4.2(3.9r -5.9s) +7.9s -9.53r

= 16.38r -24.78s +7.9s -9.53r

= (16.38 -9.53)r +(-24.78 +7.9)s

= 6.85r -16.88s
