Answer:
perimeter of a rectangular swimming pool is 154 m. Its length is ... 2x + 3x + 3 + 4x + 8 = 74. => 9x + 11 = 74. => 9x = 74 – 11. => 9x = 63 ... Solve the following equations and check your results: 2x/3 + 1 = 7x/15 + 3.
Answer:
A) 4*4x-4*3 and 16x-12
B) 12y+15y and 27y
Step-by-step explanation:
For A when you do the distributive property, you get:
4(4x-3)
4*4x-4*3 (which is one of the choices)
16x-12 (which is one of the choices)
For B when you combine like terms, you get:
12y+5y+10y
12y+15y (which is one of the choices)
27y (which is one of the choices)
Add all those numbers and divide by 6 will get you 78
The answer would be x=2936.7
