Sal bought a house for $78,524.60. Twelve years later he sold the house for 2 3/4 times as much. What was the sale price of the
coldgirl [10]
You have to divide your total by 4 to figure out what 1/4 of the price would be. That makes 1/4 of the price $19,631.15  So really you could just do $78,524.60 x2 to figure out the 2x  which is $157,049.20 and then do $19,631.15 x3 to figure out the 3/4 amount which is $58,893.45.  Then add the two numbers to get $215, 942.65

Need help with some practice questions since all are different types I'm asking alot sorry!​
sasho [114]

Answer:

Yes

Step-by-step explanation:

If they're perpendicular, that means that angle ECM = 90 degrees and angle ACE = 90 degrees. To figure out if this works, plug that into the two equations they give:

ECM = 3x + 15

becomes

90 = 3x + 15

75 = 3x

25 = x

ACE = 4x - 10

becomes

90 = 4x - 10

100 = 4x

25 = x

Since you get x = 25 for both, you know that they are perpendicular because they both measure 90 degrees
