Sophie [7]

Answer:

$318.17, out of state college is $161.12 cheaper per month

Step-by-step explanation:

72*24 = 1728 + 410*4 = 1728 + 1640 = 3368 + 450 = 18/12 = $318.17

8700+650*9 = 8700 + 5850 = 14550/9 = 1616.66

8500+400*9 = 8500 + 3600 = 12100 + 1000 = 13100/9 = 1455.56

1616.67 - 1455.56= $161.11 (use $161.12)

Answer:

The proportion is \frac{35}{108} = \frac{x}{84}, and the length of the unknown side is \frac{245}{9} or 27.22 approximately rounded to the nearest hundredth.

Step-by-step explanation:

Since the triangles are similar, the proportion of corresponding sides are equal. The pairs of corresponding sides in these triangles which we'll use to solve it are LK, KE, MK, and KF. LK and KE are corresponding sides, and their proportion is \frac{35}{108}. MK and KF are corresponding sides, and their proportion is \frac{x}{84} in which x represents the missing side. The proportions are equal, so \frac{35}{108} = \frac{x}{84}. Multiply both sides by 84 to isolate the variable, and you'll get x = \frac{35*84}{108}, which is \frac{2940}{108} or \frac{245}{9}.

PLS HELP ME ASAP WITH THIS! (LOTS OF POINTS!) (show work OR explain)
riadik2000 [5.3K]
So they tell you to let x represent the cost of Deandra's sofa. So since Selena's sofa costs 30 dollars LESS than HALF the cost of Deandra's, we know we have to divide by 2 and subtract 30. 
The equation would be x/2-30. (B)
