(a) Without solving the equation we can't determine whether its true or false.
(b) If x = 3
4x + 1 = 2x + 5
4(3) + 1 = 2(3) + 5
12 + 1 = 15 + 5
13 = 20
No, if x = 3, the equation will not be true.
(c) 4x + 1 = 2x + 5
4x - 2x = 5 - 1
2x = 4
x = 4/2
x = 2
This shows that x = 2 makes the equation true.
For this case we can make the following rule of three:
1 square mile -------------------> 4.6 * 10 ^ 4 pieces of trash
1.2 * 10 ^ 8 square miles -------> x
From here, we clear the value of x:
We have then:
x = (1.2 * 10 ^ 8) * (4.6 * 10 ^ 4)
x = 5.52 * 10 ^ 12 pieces of trash
Answer:
there are 5.52 * 10 ^ 12 pieces of trash in the earth's oceans
