Answer:
93.75
Step-by-step explanation:
well think about this he purchased 7 songs then he is left with $ 41.25 on his card then he bought 18 songs for 27.50 would tell you how much was used what it wants is for you to figure out the starting number using the equation 7+18= 25 and 41.25+27.50= 68.70. which would make 68.70+ 25= 93.75
Answer:
The solution is (-1/2, 3 1/2), or (-0.5, 3.5)
Step-by-step explanation:
Seeing that -x + 3 = y (in the second equation), substitute -x + 3 for y in the first equation, obtaining:
-x + 3 = 3x + 5
Combining the x terms, we get
3 = 4x + 5
Combining the constants, we get
4x = -2, or x = -1/2
Seeing that -x + 3 = y, substitute -1/2 for x and calculate y:
-(-1/2) + 3 = y = 3 1/2
The solution is (-1/2, 3 1/2), or (-0.5, 3.5)
11 squares, because if it's square then both sides are equal, and 11 x 11 is 121.
