12. It's similar to having an infinite number of solutions because there isn't a specific solution to answer the question.
13. For the equation 0.9x + 5.1x - 7 = 2(2.5x-3), there is only one solution and it is x=1
14. The error that your friend made was that she added extra 16x to the equation. the correct answer is that there is no solution.
16. the equation 6 (x+2)= 5 (x+7) has only one solution. it is x=3.
sorry i wasn't able to answer the other 3,
by the way you don't need to send money, because we are here to help
What is the total weight of the water in the pool when it is completely filled?
V = L * W * D
V = 18 * 9 * 54/12
V = 18 * 9 * 4.5
V =729 cubic feet
729 cubic feet of water times 62.4 pounds = 45489.6 pounds
Let
x = scale
For this case you should count how many divisions there are in the longest dimension.
14
Then, as the longest dimendion of the park is 63 meters then, the scale is
14x = 63
x = 63/14
x = 4.5
answer
the scale is 4.5m
